This article is an empirical study of slope heterogeneity in job satisfaction. It provides evidence from the generalized ordered probit models that different job characteristics tend to have different distributional impacts on the overall job satisfaction. For instance, standard models tend to significantly underestimate the effects of monthly salary and hours worked at generating the ‘highly’ satisfied workers, while lowering the incidence of the ‘very dissatisfied’ workers. Although our results should be viewed as illustrative, we provide discussions of their potential implications for employers and on how they could help with the design of employment contracts.
