The authors present evidence of a new propagation mechanism for wealth inequality, based on differential responses, by education, to greater inequality at the start of economic life. The paper is motivated by a novel positive cross-country relationship between wealth inequality and perceptions of opportunity and fairness, which holds only for the more educated. Using unique administrative micro data and a quasi-field experiment of exogenous allocation of households, the authors find that exposure to a greater top 10% wealth share at the start of economic life in the country leads only the more educated placed in locations with above-median wealth mobility to attain higher wealth levels and position in the cohort-specific wealth distribution later on. Underlying this effect is greater participation in risky financial and real assets and in self-employment, with no evidence for a labor income, unemployment risk, or human capital investment channel. This differential response is robust to controlling for initial exposure to fixed or other time-varying local features, including income inequality, and consistent with self-fulfilling responses of the more educated to perceived opportunities, without evidence of imitation or learning from those at the top.
This dissertation contains five independent chapters dealing with wage dispersion and unemployment. The first chapter deals with the explanation of international changes in wage inequality and unemployment in the 80s and 90s. Both theoretically and empirically, social benefits and its link to average income are blamed for the different experiences across countries. The second chapter discusses the search framework, to explain residual wage inequality and finds that institutional wage compression has ambiguous effects on employment. In the third chapter, we apply the theory to German data. We show that job-to-job transitions are important in explaining both frictions and career advances. In the fourth chapter, we empirically assess the relationship between wage dispersion and unemployment for homogeneous workers. We find that neither a frictional nor a neo-classical view in explaining this relationship are convincing. Unemployment within cells is not negatively correlated with wage dispersion. Finally, the last chapter builds a theoretical model which treats heterogeneous individuals in a production function framework and a frictional labor market. The model generates both wage dispersion within and between skill groups and both frictional and structural unemployment. In sum, the dissertation stresses the importance of modelling frictions to understand different types of wage inequality and unemployment.
