We develop a standard search-matching model in which mobility costs are so high that it is too costly for workers to relocate when a change in their employment status occurs. We show that, in equilibrium, wages increase with distance to jobs and commuting costs because firms need to compensate...

Consider a principal-agent relationship in which more effort by the agent raises the likelihood of success. Does rewarding success, i.e., paying a bonus, increase effort in this case? I find that bonuses have not only an incentive but also an income effect. Overall, bonuses paid for success may...

This paper examines the connection between illegal migration, minimum wages and enforcement policy. We first explore the employers' decision regarding the employment of illegal migrants in the presence of an effective minimum wage. We show that the employers' decision depends on the wage gap...

The generalized entropy class of inequality indices is derived for Generalized Beta of the Second Kind (GB2) income distributions, thereby providing a full range of top-sensitive and bottom-sensitive measures. An examination of British income inequality in 1994/95 and 2004/05 illustrates the...

Multilevel models are widely used in education and social science research. However, the effects of omitting levels of the hierarchy on the variance decomposition and the clustering effects have not been well documented. This paper discusses how omitting one level in three-level models affects...

We investigate a team setting in which workers have different degrees of commitment to the outcome of their work. We show that if there are complementarities in production and if the team manager has some information about team members, interventions that the manager undertakes in order to...
