We argue that using wage data alone, it is virtually impossible to identify whether Assortative Matching between worker and firm types is positive or negative. In standard competitive matching models the wages are determined by the marginal contribution of a worker, and the marginal contribution...

We address a basic diffculty with incorporating fairness into standard utilitarian choice theories. Standard utilitarian theories evaluate lotteries according to the (weighted) utility over ?nal outcomes and assume in particular that a lottery is never preferred over getting the most preferred...

Poverty remains one of the greatest problems of our time, causing starvation and humiliation in poor countries and contributing to problems of conflict, migration and environmental degradation effecting also richer countries. This study provides a systematical analysis of today’s donor...

We study how job seekers respond to wage announcements by assigning wages randomly to pairs of otherwise similar vacancies in a large number of professions. High wage vacancies attract more interest, in contrast with much of the evidence based on observational data. Some applicants only show...

Twelve percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used a third of the time. To analyze the Malawian epidemic, a choice-theoretic general equilibrium search model is constructed. In the developed framework, people select...

The introduction of firm size into labor search models raises the question how wages are set when average and marginal product differ. We develop and analyze an alternative to the existing bargaining framework: Firms compete for labor by publicly posting long- term contracts. In such a...

This paper investigates the importance of the age composition for pandemic policy design. To do so, it introduces an economic framework with age heterogeneity, individual choice, and incomplete information, emphasizing the value of testing. Calibrating the model to the US Covid-19 pandemic...

Helping job seekers to identify suitable jobs is a key challenge for policy makers. We develop and evaluate experimentally a novel tool that provides tailored advice at low cost and thereby redesigns the process through which job seekers search for jobs. We invited 300 job seekers to our...
