The aim of this research is to investigate the relationship between obesity and wages, using data for nine countries from the European Community Household Panel (ECHP) over the period 1998-2001. We improve upon the existing literature by adopting a Quantile Regression approach to characterize the heterogenous impact of obesity at different points of the wage distribution. Our results show that (i) the evidence obtained from mean regression and pooled analysis hides a significant amount of heterogeneity as the relationship between obesity and wages differs across countries and wages quantiles and (ii) cultural, environmental or institutional settings do not seem to be able to explain differences among countries, leaving room for a pure discriminatory effect hypothesis.
本研究旨在利用1998 - 2001年期间来自欧洲共同体家庭小组（ECHP）九个国家的数据，调查肥胖与工资之间的关系。我们采用分位数回归方法来描述肥胖在工资分布不同点上的异质性影响，从而改进了现有文献。我们的结果表明：（i）从均值回归和汇总分析中获得的证据掩盖了大量的异质性，因为肥胖与工资之间的关系因国家和工资分位数而异；（ii）文化、环境或制度背景似乎无法解释各国之间的差异，这为纯粹的歧视效应假说留出了空间。
