Field evidence suggests that people belonging to the same group often behave similarly, i.e., behaviour exhibits social interaction effects. We conduct an experiment that avoids the identification problem present in the field. Our novel design feature is that each subject simultaneously is a...

This paper provides a novel microeconomic foundation for pecuniary human capital externalities in a labor market model of monopsonistic competition. Multiple equilibria arise because of a strategic complementarity in investment decisions. -- Externalities ; human capital ; multiple equilibria

We analyse an equilibrium labour market with on-the-job search and experience effects (where workers learn-by-doing). The analysis yields a standard Mincer wage equation with worker fixed effects and endogenously determined firm fixed effects. It shows that learning-by-doing increases...

We present an OLG model in which life expectancy and environmental quality dynamics are jointly determined. Agents may invest in environmental care, depending on how much they expect to live. In turn, environmental conditions affect life expectancy. As a result, our model produces a positive...

This paper analyzes the role of the period length in a search model of the labor market and argues that it has profound implications for the market equilibrium. In the model, job offers and job destruction shocks arrive according to a Poisson process in continuous time, but institutional factors...

The paper revisits the problem of wage bargaining between a firm and multiple workers. We show that the Subgame Perfect Equilibrium of the extensive-form game proposed by Stole and Zwiebel (1996a) does not imply a profile of wages and profits that coincides with the Shapley values as claimed in...
