• Digital Economy, Industrial Structure Optimization, and Agricultural Green Development Efficiency: A Double Machine Learning Causal Analysis.
  Mi Zhou, Yinchuan Cao, Li Huang.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 49-58, March 2026. ", "\nABSTRACT\nThe digital economy plays a role in encouraging green development in agriculture, which helps achieve food security, resource conservation, and sustainable development, and also helps promote the United Nations Sustainable Development Goals. This paper employs a double machine learning (DML) method to analyze the impact of the digital economy on agricultural green development efficiency and the mechanism by which it exerts this impact across 282 prefecture‐level cities in China from 2010 to 2020. The results indicate that the digital economy positively affects the efficiency of agricultural green development, even after addressing endogeneity issues and conducting robustness checks. Analysis of the mechanism shows that vertical industrial upgrading and horizontal industrial integration are the main drivers. Furthermore, heterogeneity analysis uncovers a strong compensatory effect of the digital economy, showing a more pronounced impact in non‐major grain‐producing, resource‐based, and low‐income regions. This study provides a reference for using the digital economy to promote agricultural green development efficiency in other developing countries.\n"]

• Revisiting the Framework for Modelling Carbon Allowances: The Role of Speculation in Some Forecasting Experiment?
  Jianjie Huang, Kazeem O. Isah, Oladotun D. Olaniran, Mohammed N. Ibrahim.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 59-71, March 2026. ", "\nABSTRACT\nTo align with the global goal of keeping temperature rise well below 2°C, the European Emissions Trading System (EU‐ETS) was established as a market‐based initiative to mitigate climate change. While most carbon allowances are held and traded by polluting companies for compliance, financial actors including banks, investment firms, and brokers have increasingly participated as non‐emission compliance agents (ENCAs), engaging in speculative activities that may affect market functioning. Despite widespread discussion, compelling empirical evidence on the role of speculation in carbon price dynamics has been limited. Drawing from a large Google Trends dataset, we construct a news‐based speculation index to quantify speculative pressures and integrate it into an all‐inclusive modeling framework that accounts for both emission compliance and non‐compliance dynamics. Given the inherent volatility and mixed‐frequency nature of the data, we employ the GARCH‐MIDAS model, which accommodates variables at their natural frequencies while capturing both short‐ and long‐term volatility. Our out‐of‐sample forecasts show that models incorporating speculation and composite indicators consistently outperform the benchmark GARCH‐MIDAS‐RV model in returns, volatility, and Sharpe Ratios. Speculation emerges as a significant driver of risk‐adjusted performance, particularly over medium‐ and long‐term horizons, indicating that non‐compliance actors materially influence EUA price formation. The findings have clear economic and policy implications. Regulators can use data‐driven estimates of speculation to guide market participation rules and maintain stability, while investors can enhance portfolio performance by integrating speculative signals into forecasting models. Overall, the study provides a comprehensive, economically meaningful understanding of carbon price dynamics, reconciling market fundamentals with speculative activity and informing both policy and investment strategy in the EU‐ETS.\n"]

• Exploring the Mediating Mechanism of Industrial Structure Adjustment in Economic Growth and Electricity Consumption: Evidence From China.
  Ming Meng, Xinxin Li, Tingting Pang.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 72-82, March 2026. ", "\nABSTRACT\nUsing a hierarchical regression model and China's provincial panel data from 2001 to 2022, this paper investigates the mediating mechanism of industrial structure adjustment in the relationship between economic growth and electricity consumption. Findings reveal a positive effect of economic growth on electricity consumption, with electricity consumption increasing by 0.937% for every 1% increase in real gross domestic product (GDP). Economic growth also plays a crucial role in adjusting and upgrading industrial structure, which drives local industries toward high‐value chains. Furthermore, this study identified negative mediating effects of industrial structure adjustment on electricity consumption, with a total effect size of −0.085%. Specifically, the mediating effects of rationalization, upgrading, and softening of industrial structure are −0.018%, −0.021%, and −0.046%, respectively. Finally, heterogeneity analysis indicates that the negative effect of industrial structure adjustment is stronger in the central and western regions. In light of these findings, this study offers policy implications to achieve green and low‐carbon energy transition and high‐quality economic growth.\n"]

• Green Finance Under Climate Risks: A Comparative Analysis of Hedging Effects Between Green Bonds and Green Stocks.
  Ting Wang, Chi‐Wei Su, Hsuling Chang, Oana‐Ramona Lobonţ.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 83-93, March 2026. ", "\nABSTRACT\nInvestigating the hedging effectiveness of green finance against climate risks is essential for optimizing investment strategies. This study employs the rolling‐window wavelet correlation method to capture the time‐varying and multiscale relationships among green bond (GB), green stock (GS), climate physical risk index (PRI), and transition risks index (TRI). The empirical results show that GB serves as a stable short‐term hedge against climate transition and physical risks, supported by their fixed‐income nature and alignment with climate‐oriented investment demand. In contrast, GS correlates negatively with TRI in the short run but shows strengthening hedging ability against physical risks after mid‐2018. Over longer horizons, GS demonstrates stronger hedging effectiveness against both risk types, with relatively consistent performance in hedging against physical risks. But GB shows weaker and less consistent hedging capacity, often correlating negatively at the fortnightly scale and partially turning positive monthly. Despite both assets remaining vulnerable to systemic financial disruptions, their complementary hedging profiles support strategic diversification within multihorizon portfolios to improve climate risk resilience. Against the backdrop of the escalating climate crisis, this paper offers strategic insights for investors, policymakers, and regulators to enhance climate risk resilience through green finance.\n\nJEL Classification: C32, Q54, G12\n"]

• Testing the Safe‐Haven Properties of Green Bonds, Gold, and Bitcoin for Traditional Bonds: A Wavelet Quantile Correlation Approach.
  Chi‐Wei Su, Yu‐Mei Ding, Kai‐Hua Wang, Xiao‐Qing Wang.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 16-29, March 2026. ", "\nABSTRACT\nIn this paper, the safe‐haven attributes of green bonds, gold, and bitcoin are compared to those of traditional bonds under various time periods and quantiles by using the WQC methodology. The results indicate that green bonds exhibited a stable safe‐haven function at longer time horizons during the full sample period, whereas other assets did not have safe‐haven features. During the COVID‐19 pandemic, bitcoin exhibited safe‐haven attributes at all time horizons, whereas gold demonstrated these characteristics over the short and medium terms. In the sample period during the Russia–Ukraine war, green bonds had strong safe‐haven properties at shorter and middle time horizons, whereas bitcoin had these properties at longer time spans. In this paper, a multivariate network framework that includes green bonds, gold, and bitcoin is constructed, and the theoretical foundations that influence the safe‐haven attributes of assets are detailed. In addition, this study clearly presents the safe‐haven effects of assets under various sample periods, time horizons, and quantiles, thereby bridging the gap of existing studies that ignore time frequency. Thus, this paper provides advice for investors, regulators, and policy‐makers, such as choosing portfolios on the basis of asset characteristics, monitoring asset disclosure, and encouraging the trading of safe‐haven assets.\n"]

• Sector‐Specific Exchange Rate Movements in Hong Kong Stock Market.
  Nazif Durmaz, Song Yang, Dechen Wang.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 30-48, March 2026.

Using quarterly data between 2005 and 2024 for 10 sector‐specific industries, our findings reveal significant and asymmetric effects of currency appreciation and depreciation across various industries. Sectors such as finance, healthcare, consumption, and energy exhibit high sensitivity to exchange rate movements, influenced by trade exposure and macroeconomic conditions. The study underscores the necessity of nonlinear models to capture the complex interactions between exchange rates and equity markets. Additionally, macroeconomic variables play crucial roles in determining stock market performance, highlighting the multifaceted nature of financial market behavior in an open economy like Hong Kong. These insights extend the empirical literature and offer practical guidance for investors and policymakers, emphasizing the need for sector‐specific risk management strategies, targeted policy support, and enhanced macroeconomic coordination to mitigate the adverse effects of currency volatility and bolster Hong Kong's financial system against global economic shifts.\n"]

• Do Minimum Wages Increase Female Employment? Evidence From a Meta‐Analysis.
  Xiaomei Li, Yulin Liu, Xu Si.
  Australian Economic Papers. March 02, 2026
  ["Australian Economic Papers, Volume 65, Issue 1, Page 1-15, March 2026. ", "\nABSTRACT\nOne of the purposes of minimum wage legislation is to protect women workers. However, the impact of minimum wage on female employment has been controversial. We perform a meta‐analysis to test the policy effect. After correcting for publication bias using the overall sample, the effect is positive, indicating that minimum wages actually increase female employment. We use 32 moderators as potential explanatory variables to explain the heterogeneity of the literature and find that it stems from the data characteristics and methods used in econometric estimates. In addition, education plays an important role in regulating the female employment effect of minimum wages. Furthermore, we find that the minimum wage results in an increase in female employment in developing countries, while developed countries do not benefit from the minimum wage system. This could be related to differences in industrial structure, social security coverage, and informal employment rate in the two types of countries. Our results suggest that minimum wages may be an effective policy for women who are more likely to engage in minimum wage work.\n"]

• Deciphering the Global Phillips Curve Using Sub‐National Data in India's Inflation Targeting Era: Some Policy Implications.
  Razique Anwar, Atulan Guha.
  Australian Economic Papers. February 01, 2026
  ["Australian Economic Papers, EarlyView. ", "\nABSTRACT\nOur study examines the short‐run Phillips Curve relationship using sub‐national data from India to analyze inflation and unemployment dynamics during the inflation targeting era (IT) framework under the Global Phillips Curve (GPC) framework. It aims to identify whether the established relationship varies across different inflation regimes. Using panel data from 15 Indian states from January 2016 to May 2022, we employed the Accelerationist Phillips Curve (APC) and the New Keynesian Phillips Curve (NKPC) forms of the GPC. We analyzed the relationship using panel‐data econometric techniques. We found no statistically significant Phillips Curve relationship on average; only isolated positive coefficients occur in a few short regimes with small samples, which might be random and transitory. The study indicates that inflation dynamics may differ across sub‐national levels, possibly weakening the unemployment‐inflation trade‐off in India's informal labor market. The findings suggest that traditional macroeconomic tools based on the national Phillips Curve, like monetary interventions, may not be practical in India.\n"]

• Time‐Varying Influence of Australian Economic Policy Uncertainty on Traditional Energy Sector Performance.
  Ali Nawaz, Chi Wei Su.
  Australian Economic Papers. December 21, 2025
  ["Australian Economic Papers, EarlyView. ", "\nABSTRACT\nThis study addresses the critical problem of how Australian economic policy uncertainty (AEPU) affects the performance of the traditional energy sector, a topic of increasing importance given the sector's volatility and Australia's evolving policy landscape. Previous research has established that economic policy uncertainty generally depresses energy sector performance globally; however, there is a notable gap regarding non‐linear and frequency‐dependent effects specific to Australia's traditional energy market. To fill this gap, the study employs a novel methodological approach combining quantile‐on‐quantile regression with wavelet analysis. The empirical results reveal that, in the short run, uncertainty in Australian economic policies exerts weak and inconsistent effects on the performance of the traditional energy sector. In contrast, medium‐and long‐run results clearly demonstrate that prolonged uncertainty regarding Australian economic policies leads to a downturn in the performance of the traditional energy sector in the country. Building on these insights, we offer actionable recommendations: clearer, stable long‐term energy policies can buffer the sector from AEPU's drag; fossil‐fuel firms should strengthen liquidity and adopt phased investment plans under economic policy uncertainty.\n"]

• Impacts of International Trade Integration on Emissions.
  Hang Nguyen, My Nguyen.
  Australian Economic Papers. December 17, 2025
  ["Australian Economic Papers, EarlyView. ", "\nABSTRACT\nThis study estimates how international trade integration, proxied by global value chain (GVC) participation, affects carbon emissions, addressing endogeneity with fixed effects and system GMM. We find that deeper GVC integration increases CO2 per capita, CO2 per GDP, emissions from electricity and heat production, and CO2 intensity. Disaggregation shows stronger emission effects for backward than forward participation. We also document nonlinearities: environmental impacts rise as countries become more deeply embedded in global production networks. Heterogeneity is salient: developing economies and energy‐intensive regions, especially East Asia and the Pacific, experience the largest increases. These results highlight the need for green trade policies, cleaner production technologies, and stronger environmental regulations to mitigate emissions while sustaining global trade. The study aligns with SDG 9 (industry, innovation, and infrastructure), SDG 12 (responsible consumption and production), and SDG 13 (climate action) by emphasizing the importance of low‐carbon industrialization and sustainable trade practices.\n"]

• Commodity Prices and Inflation in Indonesia: Does the Pass‐Through Really Matter?
  Mansor Ibrahim, Xuan‐Hoa Nghiem.
  Australian Economic Papers. December 16, 2025
  ["Australian Economic Papers, EarlyView. ", "\nABSTRACT\nWe estimate the commodity price pass‐through to consumer price and food price inflation for the case of Indonesia using quarterly data from Q1 2000 to Q3 2023. In the analysis, we consider the aggregate commodity price as well as its two components, namely, energy price and non‐energy price. Employing the local projections method, we find evidence supporting significant spillover from changes in aggregate commodity price, energy price and non‐energy price to consumer price inflation, which is apparent when the commodity price changes are positive, and the inflation level is high. We also document significant responses of the food prices to changes in the commodity prices under high inflation environment. Among the three commodity prices, the non‐energy price seems to have the largest pass‐through to both consumer and food price inflation. Moreover, as compared to its effects on consumer price inflation, the non‐energy price pass‐through to food price inflation is relatively stronger. These results bear important implications for monetary policy responses amid wide swings in commodity prices.\n"]

• Environmental Sustainability and the ILCC Hypothesis: The Role of Life Expectancy, Policy Stringency, and Renewable Energy in BRICS.
  Yasin Acar, Mehmet Metin Dam, Funda Kaya, Ayse Durmaz.
  Australian Economic Papers. December 07, 2025
  ["Australian Economic Papers, EarlyView. ", "\nABSTRACT\nEnvironmental sustainability has emerged as a primary policy imperative in the global battle against climate change. Yet, there remains a notable deficiency in efforts to ensure sustainability and formulate effective policies, particularly within developing economies. To address this crucial gap, we investigate the inverted load capacity curve (ILCC) hypothesis, analyzing the influence of life expectancy, environmental policy stringency, and renewable energy consumption on environmental sustainability across BRICS nations from 1998 to 2020. Utilizing annual panel data, we introduce the inverted load capacity factor (ILCF) variable as a more comprehensive measure of load capacity excess, essential for assessing environmental sustainability. Employing heterogeneous panel data techniques, including canonical cointegrating regression and the fully modified least squares estimator, we account for cross‐sectional dependence and slope heterogeneity to yield unbiased and consistent estimates. Our findings underscore several key points: firstly, life expectancy and economic growth positively impact ILCF; secondly, increased renewable energy consumption contributes to enhanced environmental sustainability; thirdly, the effect of environmental policy stringency on ILCF varies; finally, the validity of the ILCC hypothesis is confirmed for BRICS nations, suggesting an inverted U‐shaped relationship between real income and ILCF. These results advocate for prioritized renewable energy investments by decision‐makers and policymakers in BRICS countries.\n"]

• Fintech and Cross‐Sector Volatility Spillovers in the Chinese Stock Market: A Frequency‐Heterogeneity Perspective.
  Xin Li, Mengyun Guan, Zhengzheng Li.
  Australian Economic Papers. November 27, 2025
  ["Australian Economic Papers, EarlyView. ", "\nABSTRACT\nBased on data spanning January 2001 to December 2022, this paper employs the frequency connectedness method to measure the cross‐frequency volatility spillovers between the financial industry and other industries in the Chinese stock market, and utilizes the joint impulse response function to examine the joint impact of multiple dimensions of fintech on these spillover effects. The measurement of multiple dimensions of fintech innovatively employs the TF‐IDF algorithm, utilizing a vast array of Chinese news reports. The findings reveal strong total volatility spillovers and risk vulnerability across sectors, which are significantly amplified under external shocks. Moreover, spillover effects in the short‐term frequency band (within 1 year) are more pronounced than those in the long‐term frequency band (beyond 1 year), suggesting that cross‐sector risk contagion diminishes over the long run as policies improve. Further analysis indicates that fintech enhances short‐term volatility spillovers while mitigating long‐term spillovers. Additionally, the influence of various fintech dimensions on volatility spillovers exhibits heterogeneity, underscoring the dual role of fintech development across different frequency domains. This paper reveals the frequency domain heterogeneity in how fintech influences inter‐sector risk contagion, aiding in understanding the new characteristics of financial risk transmission under the backdrop of fintech, thereby assisting in the comprehensive construction of a risk warning system under new circumstances.\n"]

• A Note on Optimal Industrial Policy Towards Bertrand Homogeneous Duopoly.
  Qi Duan, Jie Ma.
  Australian Economic Papers. October 13, 2017
  Recent studies in strategic trade and industrial policy analysis suggest that an investment subsidy, in the form of an R&D subsidy, a capacity subsidy or an advertising subsidy, would be a robust industrial policy recommendation towards an international differentiated oligopoly. However, in this paper, we show that this result does not carry over to the case of a Bertrand homogeneous duopoly. This result together with the fact that the optimal industrial policy is to set an investment subsidy when in product market competition firms play a Cournot output game, imply immediately that there hardly exists a robust industrial policy recommendation towards homogeneous goods industries.

• Effect of the Tax System ON R&D Intensity, Growth, Wages and Consumption Share.
  Óscar Afonso, Ana Maria Bandeira, Manuela Magalhães.
  Australian Economic Papers. October 13, 2017
  We propose a general equilibrium knowledge‐driven (semi‐)endogenous‐growth model with horizontal R&D, which is extended to consider two types of labour, skilled and unskilled, and exogenous government expenditure, financed through taxes on financial assets and on labour income, to analyse the implications of the tax system on R&D intensity, economic growth, wage inequality and consumption share in the output. In particular, we show that: (i) taxes have negative influence in the consumption share, being higher the marginal effect of the labour‐income tax; (ii) for any given government expenditure share, an increase (a decrease) in financial‐assets tax decreases (increases) the labour‐income tax; (iii) only the financial‐assets tax affects negatively the R&D intensity and the skill‐premium; thus, to reduce the skill‐premium the financial‐assets tax must increase; (iv) ignoring the effect on wage inequality and on R&D intensity, taxes are substitutes.

• Does Institutional Quality Matter for Financial Development and Growth? Further Evidence from MENA Countries.
  Ali M. Kutan, Nahla Samargandi, Kazi Sohag.
  Australian Economic Papers. September 26, 2017
  This study scrutinises the role of institutional quality in the linkage of financial development and economic growth in 21 Middle East and North African (MENA) countries. Using the common correlated effect mean pooled approach and annual data for the period 1980–2012, we find that not all measures of financial development promote economic growth in the absence of institutional quality, but they all augment growth in the presence of institutional quality. Furthermore, we find that foreign direct investment enhances the growth of MENA countries by the development of financial markets.

• The Bilateral J‐Curve in Australia: A Nonlinear Reappraisal.
  Mohsen Bahmani‐Oskooee, Muhammad Shafiullah, Faridul Islam.
  Australian Economic Papers. September 26, 2017
  Since the introduction of error‐correction and cointegration techniques, the J‐curve effect implies an initial short‐run deterioration of the trade balance, followed by improvement later due to currency devaluation. In a previous study of Australia’s bilateral trade, with each of her 23 partners, using the linear Autoregressive Distributed Lag (ARDL) approach we found the J‐curve effect in the model with the United Kingdom only. However, after incorporating the ARDL model that allows for nonlinear adjustment of exchange rate changes, we found the effect on four more partners – all asymmetrically. Furthermore, we document short‐run asymmetry in exchange rate changes in almost all models; short‐run adjustment asymmetry, and impact‐asymmetry in almost half of the models.

• Optimal Sovereign Debt for an Overdebted Country.
  Basil Dalamagas, Stefanos Tantos.
  Australian Economic Papers. June 06, 2017
  In this study, the role of debt maturity is analysed in a framework that blends a number of key macro‐economic factors with a process of estimating an optimal debt maturity maximising net present value. The purpose is to reduce the real value of government liabilities for a highly indebted country, as for example in the case of Greece, over a 35‐year period. The conclusion that emerges is that management of debt maturity is an essential component of the equilibrium policy and, as such, it can play an important role both in implementing tax smoothing programmes and in reducing costs associated with debt financing.

• Cyclical Multiplier and Zero Low Bound Effects of Government Expenditure on Economic Growth: Evidence for Greece.
  Constantinos Alexiou, Joseph G. Nellis.
  Australian Economic Papers. June 06, 2017
  This study explores the impact of government expenditure multipliers on economic growth utilising an Autoregressive Distributed Lag (ARDL) approach. We provide evidence on the short‐term dynamics as well as the long‐run expenditure multiplier effects on economic growth for the Greek economy over the period 1960–2014. We find that the size of the multiplier does not differ substantially over the phases of the business cycle. Our results also indicate that irrespective of the scale of inflation, government expenditure positively affects economic growth, whilst inconclusive evidence is obtained in the case of exceptionally low interest rates.

• Diversification into Emerging Markets – An Australian and the US Perspective Using a Time‐varying Approach.
  Rakesh Gupta, Junhao Yang, Thadavillil Jithendranathan.
  Australian Economic Papers. June 06, 2017
  Over the past two decades, a number of studies have examined the benefits of diversifying equity investments internationally, particularly into emerging markets. In the portfolio construction process, many researchers have criticised Markowitz's Portfolio Theory because of its inherent assumptions such as symmetric and constant correlations. In this study, we use a conditional copula model to estimate the time‐varying asymmetric correlations of stock markets and construct optimal portfolios by using estimated correlations. We find that optimised portfolios provide significant benefits for both Australian and the US investors. Out‐of‐sample results show Copula model provides results closer to the in‐sample‐estimated benefits of diversification. The results have important implications for portfolio managers who seek to diversify into emerging markets.

• Choosing Price or Quantity? The Role of Delegation and Network Externalities in a Mixed Duopoly.
  Yasuhiko Nakamura.
  Australian Economic Papers. June 06, 2017
  This paper considers a differentiated goods managerial mixed duopoly composed of one social welfare‐maximising public firm and one profit‐maximising private firm. We model the firm choice of the strategic contract. We find that when the strength of network effects is sufficiently strong, the price competition can become the unique equilibrium market structure. Furthermore, we show that there exists an area of the degree of product differentiation and the strength of network effects such that the situation wherein the public firm chooses its price contract whereas the private firm chooses its quantity contract can become the unique equilibrium structure.

• Ownership Structure and Capital Structure: A Study of Vietnamese Listed Firms.
  Thi Phuong Vy Le, Kathy Tannous.
  Australian Economic Papers. March 23, 2017
  This paper examines the relationships between ownership structure and capital structure for non‐financial listed firms in Vietnam during the period 2007–2012. Although different approaches are applied in this research, all results from those models are consistent. The study finds that while foreign ownership has a negative impact on leverage, state ownership has a positive influence. Managerial ownership has a positive relation with debt level, while the effect of large ownership on debt level is not conclusive.

• Management Behaviour in Vietnamese Commercial Banks.
  Thanh Pham Thien Nguyen, Son Hong Nghiem, Eduardo Roca.
  Australian Economic Papers. March 23, 2017
  This study identifies managerial behaviour in Vietnamese banks between the years 2000 and 2014, based on the managerial framework of banks, as identified by Rossi et al. (). This framework is built on the interrelationships between efficiency, risk, capital and diversification. This study uses the Z‐score to measure insolvency risk, the SFA to estimate cost efficiency, the ratio of total equity to total assets to capture bank capital and the HHI index to measure the diversification of revenue and earning assets. The results from the 3SLS estimator indicate that revenue diversification has an insignificant impact on insolvency risk, capital ratio and cost efficiency, but earning assets diversification has a negative effect on these three variables, supporting ‘classical diversification’, ‘economic capital’ and ‘monitoring’ behaviours. Moreover, a decline in cost efficiency leads to a rise in insolvency risk, implying ‘bad management’ behaviour; an increase in risk results in a reduction in cost efficiency, indicating ‘bad luck’ behaviour; and a reduction in capital ratio in the poorly capitalised banks leads to a growth in risk, suggesting ‘moral hazard’ behaviour. The results remain strongly robust when using an alternative risk measurement (the loan loss provision ratio) and an alternative SFA model.

• Firm Value, Corporate Cash Holdings and Financial Constraint: A Study from a Developing Market.
  Thi Lien Hoa Nguyen, Le Ngan Trang Nguyen, Thi Phuong Vy Le.
  Australian Economic Papers. March 23, 2017
  This paper investigates the nonlinear relationship between firm value and corporate cash holdings in a sample of non‐financial Vietnamese firms from 2008 to 2013. We focus on both static and dynamic regressions to test for a nonlinear relationship. Our results reveal an ‘inverse U‐shape’ relationship between firm value and cash holdings, which is in line with trade‐off theory. Specially, we further test whether the optimal cash level changes under different financial conditions. In turn, this paper shows evidence of a nonlinear relationship between firm value and cash holdings under different financial circumstances and that each type of firm will adjust its optimal cash level based on business conditions.

• Out‐of‐Sample Exchange Rate Forecasting and Macroeconomic Fundamentals: The Case of Japan.
  Takashi Matsuki, Ming‐Jen Chang.
  Australian Economic Papers. March 23, 2017
  This study explores the respective out‐of‐sample exchange rate forecasting abilities of five macroeconomic fundamental models in comparison to a naïve random walk model for Japan during the post‐Bretton Woods era. To assess the influence of major economic changes, we estimate both linear and nonlinear models for all the macroeconomic fundamentals. Overall, most structural exchange rate models outperform a naïve random walk model in terms of forecasting accuracy in the short horizon. When the fundamentals are only linearly modelled, the forecasting ability of the Taylor rule is generally superior to other fundamental models. When the fundamentals are nonlinearly specified, the predictability of some other models rises dramatically to match that of the Taylor rule models in short and/or long horizons. Of importance, we determine that the yen/dollar exchange rate forecasting performance effectively improves in several fundamental models when influential economic changes are incorporated.

• Interest Rate Linkages between Offshore and Onshore Renminbi Markets.
  Yongqi Feng, Tianshu Zhang.
  Australian Economic Papers. March 23, 2017
  We examine the interest rate volatility spillover between the offshore and onshore Renminbi (RMB) markets. The Hong Kong inter‐bank RMB offer rate (CNY HIBOR) and the Shanghai inter‐bank offer rate (SHIBOR) are used, respectively, as the interest rates for the offshore and onshore RMB markets. The results of our research show that there was significant volatility spillover between the offshore and onshore RMB prior to 21 June 2013 and that direction of the spillover from the SHIBOR to the CNY HIBOR is stronger than that from CNY HIBOR to SHIBOR. However, the spillover declined in strength between 21 June 2013 and 20 April 2016. We also find that the interest rate correlations are low and unstable. Our research reveals that the offshore RMB interest rate has been an independent system that is not determined by the onshore market, and that the determination of the offshore RMB interest rate is very complicated. The Hong Kong market is increasingly playing a more important role in the determination of the RMB. This study contributes to our understanding of the interest rate determination in China and has important implications for policy makers in terms of interest rate policies in the offshore and onshore RMB markets.

• Capital Inflows and House Prices: Aggregate and Regional Evidence from China.
  Hui An, Lijie Yu, Rakesh Gupta.
  Australian Economic Papers. March 23, 2017
  Rising house prices in China have been of concern for investors and policymakers. Prices have risen substantially in the last decade, especially in large urban cities, and some economists have expressed concerns about the affordability of residential housing for young adults. This phenomenon becomes a major concern for policymakers, in terms of managing policies to balance the residential needs of individuals and the transition to a market economy. Theoretically, house prices ought to be linked to economic factors such as disposable income, availability of land to build and credit policy. However, it appears that traditional economic theories fail to appropriately explain house prices in China. We provide an explanation from the perspective of capital inflows into China. In terms of per capita remittances, China receives the highest inflow of foreign capital, and this may have a significant impact on risk adjusted returns in the Chinese market. To investigate this relationship, we use the vector error correction model to assess the impact of capital inflows on house prices. We find that capital inflows have a significant positive effect on house prices. The study makes important contributions to understanding the relationship between house prices and foreign remittances after controlling for other economic factors. China is a large economy. Because the impact of economic development in China has not been consistent across the country, we address the regional differences in the house price changes to capital inflows. Using regional data, we show that capital inflows have an asymmetric effect on the housing market across different provinces and cities of China. This has important implications for the development of economic policies in China that aim to provide fair access to residential housing for everyone. These findings are also relevant to investors in the housing market, whether investing for a personal residential home or as part of their diversified investment portfolio. It will also be informative to see how a reversal of capital inflows associated with tighter financing conditions in advanced countries will affect house prices in China.

• Business Cycle Asymmetries and Nonlinearity in UAE Macroeconomic Time Series.
  Mohamed Osman, Ariful Hoque, Kamrul Hassan.
  Australian Economic Papers. March 23, 2017
  This study investigates the dynamic behaviour of macroeconomic time series variables of the United Arab Emirates. We first examined whether there are non‐Gaussian characteristics associated with the macroeconomic variables of the United Arab Emirates. Through application of the BDS nonlinearity test, our results indicated that there is a substantial nonlinear dependence in the data set for all the variables. We also assessed the asymmetric behaviour of these variables by exploring whether they exhibit two particular forms of asymmetry, which are deepness and steepness asymmetries. These results have shown that there is no empirical evidence of business cycle asymmetry in all the variables at any conventional level of significance in the sample period. Also, through application of further robust testing, our findings indicate the presence of pro‐cyclical asymmetry in some of the variables and at the same time indicate the presence of asymmetries in the volatility.

• Designing the optimal public pension system.
  Takao Fujii, Fumiaki Hayashi, Jun Iritani, Kazumasa Oguro.
  Australian Economic Papers. January 20, 2017
  This paper uses a two‐period overlapping generations model in order to provide a theoretical design for the optimal public pension system based on a partial equilibrium analysis. Household preferences depend on two periods' consumption and leisure and are positively homogeneous of degree m with respect to consumption in the working and retired periods. We present characteristic features of the optimal public pension system in this paper. First, differences in the population growth rate do not affect the large/small relation between the optimal net lifetime burden rates of generations. Second, we present the optimal public pension system explicitly if m < 1 and m ≠ 0. Third, the difference between the market time‐preference rate and the social time‐preference rate provides a crucial insight into the optimal burden rate of each generation.

• Corporation Diversification and Firm Performance: Evidence from Vietnamese Listed Firms.
  Duc Nam Phung, Anil V. Mishra.
  Australian Economic Papers. January 20, 2017
  We examine the effect of corporate diversification on the performance of firms listed on the Vietnamese stock exchanges, using 2744 firm year observations over the period from 2007 to 2012. We find that corporate diversification has a negative impact on firm performance. Our results are robust to various econometric estimation techniques including fixed effect, instrumental fixed effect, Heckman selection model and system generalised method of moments. In the Vietnamese context, the lack of an efficient corporate governance system may encourage firms to follow corporate diversification strategies, thus impairing their performance.

• Environmental Kuznets Curve with Adjusted Net Savings as a Trade‐Off Between Environment and Development.
  Martin Neve, Bertrand Hamaide.
  Australian Economic Papers. January 20, 2017
  The Environmental Kuznets Curve (EKC) hypothesises that emissions first increase at low stages of development then decrease once a certain threshold has been reached. The EKC concept is usually used with per capita Gross Domestic Product as the explanatory variable. As others, we find mixed evidence, at best, of such a pattern for CO2 emissions with respect to per capita GDP. We also show that the share of manufacture in GDP and governance/institutions play a significant role in the CO2 emissions–income relationship. As GDP presents shortcomings in representing income, development in a broad perspective or human well‐being, it is then replaced by the World Bank's Adjusted Net Savings (ANS, also known as Genuine Savings). Using the ANS as an explanatory variable, we show that the EKC is generally empirically supported for CO2 emissions. We also show that human capital and natural capital are the main drivers of the downward sloping part of the EKC.

• Australian Bond Excess Returns: An Asset Allocation Perspective.
  Rui Chen, Meng Wang, Jiri Svec.
  Australian Economic Papers. January 20, 2017
  We examine the out‐of‐sample predictability of excess returns in the Australian government bond market. Our results confirm previous findings that a linear combination of forward rates provides a statistically significant prediction of bond excess returns on 1‐ to 5‐year maturity bonds. However, from an asset allocation perspective, our predictive model fails to obtain positive economic utility against the no‐predictability benchmark. Our results are robust to the sample period and different parameter assumptions.

• Government Size and Stochastic Growth.
  Shin‐Chyang Lee, Shang‐Fen Wu, Cheng‐Te Lee.
  Australian Economic Papers. January 20, 2017
  This paper analyses the effects of the size of government on economic growth in a stochastic endogenous growth model involving the supply‐side effect and demand‐side effect produced by government spending. We show that a rise in the government spending affects economic growth through three channels, including the crowding‐out effect, the spin‐off effect and the resource mobilisation effect. We demonstrate that there exists an optimal size of government that maximises the economic growth rate.

• Endogenous Growth and Intellectual Property Rights: A North–South Modelling Proposal with Population Ageing.
  Mónica L. Azevedo, Óscar Afonso, Sandra T. Silva.
  Australian Economic Papers. September 19, 2016
  This paper studies the effect of intellectual property rights (IPR) on economic growth, in the light of population ageing, i.e., in a more realistic context. The analysis is motivated by the implications of population ageing on economic growth. Moreover, this study analyses this relationship in a north–south framework where there is a healthcare sector. We conclude that population ageing has no impact on the sign of the IPR effect on economic growth. However, it positively affects the steady‐state growth rate. Finally, under some conditions, the presence of the healthcare sector also increases the steady‐state growth rate.

• Economic Integration, Growth and Income Distribution.
  Kuo‐Hsing Kuo, Cheng‐Te Lee.
  Australian Economic Papers. September 19, 2016
  This paper constructs a two‐sector growth model with heterogeneous labour, to explore the impact of the economic integration on growth and income distribution. There are two sectors in each country, including the consumption‐good sector and the R&D sector. We suppose that the R&D sector produces new blueprints or ideas for these innovations, and hence provides the engine of growth. Assume that the talent's distribution of workers is the uniform distribution. We show that the economic integration will stimulate the developing countries' economic growth and then decrease its income inequality. In addition, we also demonstrate that if the growth rate of the advanced country rises after the integration, then income inequality of that will increase, and vice versa.

• Monetary Policy Transmission in Vietnam: Evidence from a VAR Approach.
  Xuan Vinh Vo, Phuc Canh Nguyen.
  Australian Economic Papers. August 25, 2016
  A thorough understanding of the transmission mechanism is a key requirement for central banks for successful implementation of monetary policy. This paper investigates the existence of the interest rate channel, exchange rate channel and asset price channel in Vietnam by employing a vector autoregressive model analysis using monthly data ranging from 2003M1 to 2012M12. The results from the analysis present evidence for a cost channel. However, we find no evidence for the existence of an exchange rate channel or asset price channel of monetary transmission in Vietnam.

• Asymmetry Effects of Exchange Rate Changes on Domestic Production: Evidence from Nonlinear ARDL Approach.
  Mohsen Bahmani‐Oskooee, Amirhossein Mohammadian.
  Australian Economic Papers. June 03, 2016
  Currency depreciation is said to have positive or negative effects on domestic production. Previous studies that tried to address this issue using Australian data have been inconclusive at best but mostly showed no effects. One common feature of all studies is that they have assumed that the effects of exchange rate changes are symmetric. In this paper, we use the concept of partial sum and separate appreciations from depreciations to test whether the effects are symmetric or asymmetric. Application of the nonlinear ARDL approach of Shin et al. (2014) reveals that indeed the effects of changes in the real effective exchange rate of the Australian dollar are asymmetric in the short run as well as in the long run. While in the short run both appreciations and depreciations affect Australian domestic production, only effects of appreciation last into the long run, a unique finding.

• Optimal Intertemporal Consumption and Involuntary Memories of Consumption.
  Stan Miles, Peter Smoczynski.
  Australian Economic Papers. June 03, 2016
  Recent studies introduce the notion of treating autobiographical memories of past pleasurable experiences as assets and expanding the discounted utility model to include the utility of memories of past consumption. Recent studies in psychology have found that involuntary autobiographical memories are common in everyday life. This paper builds on these two strands in the literature by expanding the discounted utility model to include the utility of involuntary memories of past consumption. Optimal control theory is used to develop a continuous‐time optimal consumption model that takes into account the fact that consumption may generate involuntary memories that arrive at random times. The model is used in an in‐depth analysis of optimal consumption with memories. It is shown that memories shift consumption to earlier times. This effect gets weaker as the time horizon gets longer, and it vanishes entirely when the time horizon is infinite.

• Monetary Policy Announcements, Communication, and Stock Market Liquidity.
  Jieun Lee, Doojin Ryu, Ali M. Kutan.
  Australian Economic Papers. May 25, 2016
  Using the high‐quality intraday transaction data from 2001–2012, we investigate changes in stock market liquidity in response to the monetary policy announcements of the Bank of Korea (BOK). We find that liquidity impairment associated with informed trading occurs prior to the announcements but it disappears subsequent to the global financial crisis. In addition, liquidity impairment appears to become more severe with insufficient experts' predictability and accuracy rather than with policy rate change itself and unscheduled announcements. Finally, the Federal Open Market Committee (FOMC) announcements, changes in the Volatility Index (VIX), and trading by foreign investors play a limited role in explaining stock market liquidity changes. Overall, results indicate that central bank communication plays a significant role in reducing liquidity impairment by enhancing the predictability of policy actions, and therefore, mitigating information asymmetry.

• “Fair go” for all? Wealth and Risk Aversion of Australian Households*.
  Stamatios Tsigos, Kevin Daly.
  Australian Economic Papers. May 25, 2016
  A mean‐variance framework is applied to Australian household financial portfolios in order to provide estimates of relative risk aversion in the economy. Controlling for various socio‐economic characteristics, we explore whether risk aversion heterogeneity is a function of wealth heterogeneity. In contrast to most studies, we find evidence of very high risk aversion amongst the majority of households of poor households but vastly lower risk aversion amongst the high percentiles in the wealth distribution. Applying a first differences model across three survey waves spanning 2002 to 2010, we find that risk tolerance increases significantly with wealth. Risk tolerance is positively associated with mortgage payments, but rental payments have no relationship. In addition, we found no evidence that holding a university education has any discernible impact on risk aversion. Lastly, we present some preliminary findings as to the impact of financial advice on observed risk aversion. Financial advice is found to accentuating risk aversion, particularly amongst the wealthiest households. The findings have potential implications for the distribution of wealth in Australia that has received renewed interest recently.

• How Well Does the Australian Aged Pension Provide Social Insurance?
  Emily Dabbs, Cagri Kumru.
  Australian Economic Papers. April 18, 2016
  Social security plays an essential role in an economy, but if designed incorrectly, it can distort individuals' labour supply and savings behaviour. We explore how well the Australian means‐tested pension system provides social insurance by changing the settings of the system and calculating the impact on welfare. In order to exclude trivial welfare gains, we keep the cost of the programmes constant. We find that the means‐tested pension system is welfare reducing, but does provide a better outcome than a PAYG system of equivalent cost. We also find that if the benefit amount is held constant, and hence the cost of the pension programme is allowed to vary, a taper rate of 1.0 is optimal. However, once we hold the cost of the programme constant, a universal benefit scheme provides the best welfare outcome.

• Forecasting the Government Bond Term Structure in Australia.
  Rui Chen, Jiri Svec, Maurice Peat.
  Australian Economic Papers. April 14, 2016
  In this paper, we evaluate the performance of the dynamic Nielsen and Siegel interest rate model in forecasting Australian government bond yields. We compare a two‐stage OLS estimation procedure to a more powerful and robust state‐space framework estimated via a Kalman filter. We show that the one‐step approach generates smaller forecast errors than the two‐step procedure or a benchmark random walk model when forecasting the Australian government term structure across various horizons.

• City Size and Wage Disparity in Segmented Labour Market in China.
  Liqun Pan, Pundarik Mukhopadhaya, Jing Li.
  Australian Economic Papers. April 13, 2016
  The relation between city size and wage inequality is well established for Western countries. This paper finds that city size–wage premium exists across Chinese cities to a lower extent than the Western world. Further, using a simplified model on the Chinese Household Income Project survey data, we find that the city size–wage premium varies with difference in skills among urban citizens. The variation amounts to 50% more for the high‐skill workers compared with their low‐skill counterparts. Moreover, owing to the presence of segmented labour market, the patterns of city size–wage premium and city size–wage inequality premium are notably different for the migrants, who receive a much lesser wage than the citizens and do not experience wage variation owing to their skill heterogeneity.

• Trade and Investment Linkages and Stock Market Long‐Run Relationship.
  Sudharshan Reddy Paramati, Rakesh Gupta, An Hui.
  Australian Economic Papers. March 23, 2016
  This paper aims to examine whether the intensity of trade and investment linkages among the countries matter for their stock market long‐run relationship. To achieve this, we classify Australia's bilateral trade and investment partners into major, medium and minor. Empirical findings of an asymmetric generalised dynamic conditional correlation generalised autoregressive conditional heteroskedasticity model show that correlations are time varying and increased significantly during the global financial crisis (GFC). Results of multivariate cointegration test confirm the long‐run equilibrium relationship between the stock markets of Australia and its major partners in the pre‐GFC and during GFC. Based on the full‐sample results, it indicates that the GFC has segmented the stock markets from the long‐run equilibrium relationship. Granger non‐causality test results on full sample show that Australian stock market causes only the New Zealand market while the USA, the UK, Germany, Canada, Switzerland and Italy drives the Australian market. Our results therefore suggest that the intensity of bilateral trade and investment linkages among the countries matter for their stock markets' long‐term relationship.

• Does Ecological Footprint Impede Economic Growth? An Empirical Analysis Based on the Environmental Kuznets Curve Hypothesis.
  Gazi A. Uddin, Khorshed Alam, Jeff Gow.
  Australian Economic Papers. March 09, 2016
  This paper examines the relationship between income and environmental quality using environmental Kuznets curve (EKC) hypothesis. The hypothesised link is tested using time‐series analysis of 22 countries over the period 1961–2011. The degree of environmental impacts of economic activity is measured using ecological footprint (EF) per capita as explanatory variable, while real gross domestic product (GDP) per capita and its quadratic and cubic forms are used as predictor variables in these countries. First, the EKC hypothesis is tested through examining the relationship between EF and GDP using linear, quadratic and cubic functions. Further, the long‐run relationship between EF and GDP is investigated using a vector error correction model. It was found that there is a cointegrated relationship between the variables in almost all countries, which was statistically significant, and EKC supported in 10 countries. Additionally, almost all error correction terms are correct in sign and are significant, which implies that some percentage of disequilibria in EF in the previous year adjusts back to the long‐run equilibrium in the current year. Therefore, an efficient trade‐off between environmental protection and economic benefits should be taken, and EF should be reduced through changing consumption patterns, improving the efficiency of use of resources and cleaner technology choices.

• Leadership and Privatisation in a Mixed Multi‐product Oligopoly: An Endogenous Timing Model.
  Guangliang Ye.
  Australian Economic Papers. March 09, 2016
  This paper examines both leadership choice and welfare consequences of privatisation in an endogenous timing mixed multi‐product oligopoly. It shows that a multi‐product firm undermines the welfare‐maximising efforts of a public firm by cross‐subsidising. The paper demonstrates that a unique subgame perfect Nash equilibrium emerges in a multi‐product market, in contrast to the multiple equilibria of a single‐product market. This unique equilibrium indicates that profit‐maximising private firms retain leadership while a welfare‐maximising public firm acts as a follower. Even on the off‐equilibrium path where the public firm acts as a leader, it rarely generates maximum social welfare. However, privatising the public firm usually harms social welfare and results in a different timing structure in equilibrium.

• Do Education and Sex Matter for Intergenerational Earnings Mobility? Some Evidence from Australia.
  David Fairbrother, Renuka Mahadevan.
  Australian Economic Papers. March 09, 2016
  This paper analyses the intergenerational earnings mobility in Australia for all combinations of mothers, fathers, sons and daughters. We find that mobility is highest between parents and children of the opposite sex. Daughters are more mobile than sons with respect to fathers' earnings, but there is no statistical difference between the sexes' mobility with respect to mothers' earnings. We also consider how differing levels of mobility between the sexes may be related to the education level of the children. It was found that the father–son elasticity increases with son's education level and that the difference between son–father and daughter–father mobility may be associated with the higher levels of education obtained by females from less affluent backgrounds.

• Efficiency and Equity in Funding for Government Schools in Australia.
  Kalyan Chakraborty, Vincent C. Blackburn.
  Australian Economic Papers. December 23, 2013
  This study measures cost inefficiency for government school in New South Wales, Australia using a two‐stage data envelopment analysis (TSDEA) model and the inefficiency‐effects model (Battese & Coelli, 1995). The study found overall primary schools are 75 per cent and secondary schools are 89 per cent cost efficient. However, cost efficiency for primary schools has decreased and for secondary schools has increased marginally over the study period. The study found that social disadvantage in primary schools exerts a strong negative impact on students’ achievement scores causing inefficient use of available resources. For secondary schools no such conclusive relationship is observed.

• Some Taxation Theorems in the Hotelling Model.
  Hui Wen Cheng, Chin Wei Yang.
  Australian Economic Papers. December 23, 2013
  In this paper, we investigate the relationship between the demand ad valorem, cost ad valorem and unit taxes in terms of price, quantity and tax revenue. In particular, we prove that the Musgravian transformation holds in the Hotelling model. In addition, we show that the Suits‐Musgrave theorem must be revised as output in the Hotelling model remains invariant in the presence of different taxes. That is, for a given price instead of a given output, the tax revenue under demand ad valorem tax exceeds that under the corresponding unit tax as long as profit levels for both stores are positive, a very general assumption. The exception is when the two stores are located close to each other and transportation cost is zero. Only in this case, are tax revenues and price under both tax regimes the same. If both stores are symmetrically located, the superiority of the ad valorem tax holds true except when the two stores are located back to back. Finally the farther away the location of a firm from the end point is, the smaller the difference in tax revenues between demand ad valorem and unit tax will be: the effect of the Suits‐Musgrave theorem weakens in the presence of location clustering.

• Stock Prices and Exchange Rates in Australia: Are Commodity Prices the Missing Link?
  Nicolaas Groenewold, James E.H. Paterson.
  Australian Economic Papers. December 23, 2013
  There are still significant gaps in our knowledge of the relationship between stock prices and exchange rates; not least, the ambiguity about the sign of the coefficient linking them. One explanation which we explore in the Australian context in this paper is the omission of commodity prices. We show that a relationship which omits commodity prices performs poorly but, once commodity prices are added, our results are plausible and robust. We also throw light on the commodity‐currency issue: the link from the exchange rate to commodity prices is stronger and more consistent than that in the opposite direction.

• Eagles and Turkeys: Human Capital Externalities, Departmental Co‐authorship and Research Productivity.
  Frank Neri, Joan R. Rodgers.
  Australian Economic Papers. December 23, 2013
  Lucas (1988) hypothesised that human capital externalities explain persistent productivity growth and become manifest via interactions between workplace colleagues. Consistent with the first part of this hypothesis, Fox and Milbourne (2006) concluded that an increase in the average level of human capital in Australian economics departments raised the research productivity of departmental members. This paper tests the robustness of this finding by using a direct, rather than a proxy, measure of human capital and confirms the existence of human capital externalities within Australian economics departments. But we extend the analysis in two important dimensions. Firstly, we investigate the second part of Lucas' hypothesis by testing whether the externality becomes manifest via co‐authoring. We find no evidence that this type of interaction is associated with higher research productivity, especially for higher quality outputs. Secondly, we control for the likely endogeneity of one's peer group via instrumental variables estimation. In this case, we find that the peer group effect disappears completely for the highest quality outputs but remains for research output more broadly defined.

• Wage Inequality and Human Capital Formation under Migration Possibilities.
  Akira Shimada.
  Australian Economic Papers. December 23, 2013
  I examine the problem in the relationship between wage inequality and human capital formation under migration possibilities. Unlike previous analyses, I incorporate the education market and the education price into the analysis, and assume that workers bear the pecuniary cost for receiving education. Given such an assumption, migration possibilities do not necessarily increase education demand since the larger demand for education raises the education price and lowers the net return on education. By modelling an economy where workers in the home country (the labour‐sending country) comprise skilled and unskilled workers and they can migrate to the foreign country (the labour‐receiving country), I show that brain gain and brain drain occur simultaneously in the home country. In particular, if wage inequality is larger in the foreign country than in the home country, skilled workers experience brain gain and unskilled workers experience brain drain in the home country. On the other hand, if wage inequality is sufficiently larger in the home country, brain drain occurs in skilled workers and brain gain in unskilled workers.

• A Non‐linear Model of the Trade Cycle: Mathematical Reflections on Hugh Hudson's Classic.
  V. Ragupathy, Stefano Zambelli, K. Vela Velupillai.
  Australian Economic Papers. July 25, 2013
  Hugh Hudson's classic article on A Model of the Trade Cycle has never, to the best of our knowledge, received the serious attention it deserved. It was written in what we would like to call the classic Hicks‐Kaldor mode, i.e. relying on ingenious diagrammatic techniques for expository purposes, and, indeed, developing an innovative model of the trade cycle where interaction of monetary and real forces were modelled in terms of elements common to the classic nonlinear endogenous models of these two pioneers. In this paper we reconsider the analytical contents of Hudson's classic, and its expository technique, in the light of later, mathematical, approaches to the same topic. It is a clear example of how a mathematical reading and reformulation of an economically motivated geometric method proves fruitful in furthering the frontiers of economic analysis. Our conclusion is that there is still much to be gained in the expository style adopted by Hudson, especially when viewed mathematically; but, more importantly, there are innovative suggestions and still relevant reflections on theorising and understanding actual performances of advanced industrial economies. Above all Hudson's classic is permeated with the policy underpinnings of a rich model of the trade cycle.

• Wage‐Setting Institutions and R&D Collaboration Networks.
  Ben Ferrett, Vasileios Zikos.
  Australian Economic Papers. July 25, 2013
  We analyse how union structures that differ in the degree of wage‐setting centralisation affect the pattern of R&D network formation. Within the context of a three‐firm industry, a central union that sets a uniform wage is shown to induce a partial R&D network that includes two firms but excludes the third. In contrast, we find that, under less centralised union structures, firms have incentives to form R&D networks with a larger number of alliances. This result is consistent with the stylised facts for industrialised countries: recent decades have seen an upsurge in R&D alliances along with labour market deregulation towards more flexible wage‐setting institutions.

• Simultaneity, Forecasting and Profits in London Copper Futures.
  Barry A. Goss, S. Gulay Avsar.
  Australian Economic Papers. July 25, 2013
  Previous research on price determination for non‐ferrous metals at the London Metal Exchange (LME) suffers from three limitations: first it has employed single equation methods only, which cannot explain the simultaneous determination of spot and futures prices; second, by focusing on current and lagged prices, previous research does not analyse the effect on price determination of critical variables such as expectations, consumption and inventories; third, the outcome of prior research regarding market efficiency is ambiguous. This paper, which addresses these issues, develops a simultaneous model of the copper market at the LME, with representation of the activities of hedgers, speculators and consumers. This model produces post‐sample forecasts of the spot price which outperform conventional benchmarks, thus providing evidence against the efficient market hypothesis. Model‐derived forecasts are employed as the foundation of a trading program which produces risk‐adjusted profits (net of commission costs) for holding periods of one week and one month, thus fulfilling the ‘sufficient condition’ for market inefficiency. This study, therefore, provides new insights into price determination on the LME copper market, and resolves the ambiguity of previous research regarding the efficiency of that market. This is the first application of the model forecasting approach to the question of performance of the market for copper.

  This study investigates the entry route choices of low‐cost carriers (LCCs). A LCC considers whether to enter a spoke route or a rim route of a major carrier's hub‐spoke network. Under a Cournot schedule competition model, we demonstrate that rim entry is more profitable for LCCs if connecting passengers' hub‐through additional travel time cost is large, and spoke entry is more profitable if this time cost is small. Welfare analysis shows that rim entry is socially preferable when the time cost is large and that spoke entry is socially preferable when the time cost is small. In a certain range of time costs, however, LCCs choose spoke entry even though it is not socially preferable.
