In very different fields of economics, economic inference and policy evaluation require economists to parametrize a production function that links measures of input factors to measures of output. While doing so, strong assumptions are implicitly made about microeconomic variables governing the...

In this paper, we introduce two sources of unemployment in a two-factor general equilibrium model: search frictions and fairness considerations. We find that a binding fair-wage constraint increases the unskilled unemployment rate and can at the same time lead to a higher unemployment rate for...

The paper explains how workers' expectations of being discriminated against can be self-confirming, accounting for the persistence of unequal outcomes in the labour market even beyond the causes that originally generated them. The theoretical framework used is a two-stage game of incomplete...

In this paper we consider the interaction between local workers and migrants in the production process of a firm. Both local workers and migrants can invest effort in assimilation activities in order to increase the assimilation of the migrants into the firm and thereby increase their...

We construct a simple model incorporating various urban labour market phenomena obtaining in developing economies. Our initial formulation assumes an integrated labour market and allows for entrepreneurship, self-employment and wage employment. We then introduce labour market segmentation. In...

This paper looks at the situation of legal immigrants who employ illegal immigrants to provide them with various services. This enables the legal immigrants to allocate more time to other work, thereby increasing their earnings. Illegal immigrants employed by legal immigrants may specialize in...

This paper develops a theoretical model of a worker's decision problem under uncertainty about the optimal separation time, when holding a representative outside offer but facing fixed costs of quitting. Implications of the model's closed form solution are consistent with the quit behavior of...

This paper presents a model in which promotion of employees within the internal firm hierarchy is determined by the individuals' allocation of time between promotion/rent-seeking and productive activity. We consider the effect of an increase in the employer's knowledge (information) regarding...
