This paper uses data from the European Survey on Income and Living Conditions to offer new empirical evidence on how wage differentials are influenced by the changing economic conditions, that is, before and after the 2008–2010 recession, and shaped by the different institutional frameworks of European Union countries. We examine whether wage changes are homogeneous across groups of workers, as they are classified by their contractual relationship and working time, and by the heterogeneity in institutions that regulate and affect the labour market. Results obtained by estimating ordinary least squares and quantile regressions confirm the existence of contract and working time wage gaps and allow to estimate their different magnitudes along the wage distribution, and their rise during the recession. The impact of labour market institutions on shaping them is diverse, with more intervention of the government in the setting of the minimum wage and stricter regulation for atypical contracts reducing the wage gaps and producing larger positive effects for low-wage employees.

本文使用来自《欧洲收入和生活条件调查》的数据，提供新的经验证据，说明工资差异如何受到不断变化的经济状况（即2008-2010年经济衰退前后）的影响，并受到不同制度框架的影响。欧盟国家。我们检查了按工人的合同关系和工作时间以及按规范和影响劳动力市场的机构的异质性对工人群体的工资变化是否同质。通过估计普通最小二乘和分位数回归获得的结果证实了合同和工作时间工资差距的存在，并允许估算他们沿着工资分配的不同幅度，以及在经济衰退期间的涨幅。
