There is no robust empirical support for the effect of financial incentives on the decision towork in self-employment rather than as a wage earner. In the literature, this is seen as apuzzle. We offer a focus on the opportunity cost, i.e. the wages given up as an employee.Information on income...

It is argued that migration from Mexico to the US and its corresponding return migration aredetermined by international wage differentials and preferences for origin. We use a model ofjob search, savings and migration to show that job turnover is a crucial determinant of themigration process...

Using a matched firm-worker dataset, we show both theoretically and empirically that positiveassortative matching between firms...

Within an efficiency wage framework, we study the effects of two revenue-neutral tax reformsthat change the progressivity of the labour tax system. A revenue-neutral increase in both thewage tax and tax exemption and a revenue-neutral change in the composition of labourtaxation towards the tax...

To assess the employment effects of labor costs it is crucial to have reliable estimates of thelabor cost elasticity of labor demand. Using a matched firm-worker dataset, we estimate along run unconditional labor demand function, exploiting information on workers to correct forendogeneity in the...

We evaluate the effects of outsourcing and wage solidarity on wage formation andequilibrium unemployment in a heterogeneous labour market, where wages are determinedby a monopoly labour union. We find that outsourcing promotes the wage dispersion betweenthe high-skilled and low-skilled workers...

We study both the various consequences and the incentives of outsourcing. We argue thatthe wage elasticity of labour demand is increasing as a function of the share of outsourcing,which is importantly a result consistent with existing empirical research...
