--- - |2 The debate regarding the welfare state–weakening effect and the income inequality‐increasing effect of globalization remains a contentious issue among stratification scholars. For some, globalization increases income inequality, while for others, globalization has no, or a negligible, effect on income inequality. This study brings new evidence to bear on this debate by separately investigating effects of multiple indicators of globalization (international trade, foreign direct investment [FDI] and immigration), and of welfare state generosity (government social‐protection spending) on (1) income inequality before taxes and transfers and (2) income inequality after taxes and transfers, using data from 23 Organisation for Economic Co‐operation and Development (OECD) countries over 1990–2009. First, results show a positive effect of international trade, a negative effect of immigration, but no effect of FDI and government social‐protection spending on income inequality before taxes and transfers. Second, results show no effect of the globalization indicators but a negative effect of government social‐protection spending on income inequality after taxes and transfers. These findings suggest that (1) globalization has inequality‐increasing effects depending on measures of income inequality; (2) the welfare state, in many OECD countries, continues to shape income distribution; and (3) in contrast with the popular narrative, immigration may decrease income inequality. - 'Sociological Forum, Volume 33, Issue 3, Page 666-689, September 2018.
