In this paper, we present a model of tax evasion in the presence of imperfect auditing. We show that there is a clear link between the degree of observability associated with a given taxpayer or activity and that taxpayer’s optimal declaration strategy with respect to fiscal agency. We also...

In this paper, we introduce uncertainty of the labour productivity of women in a competitive model of wage determination. We demonstrate that more qualified women are then offered much lower wages than men at the equilibrium. This result is consistent with the glass ceiling hypothesis according...

Using the principal-agent- supervisor paradigm, this paper examines the occurrence of collusion in a setting where the principal has no information about the supervisor and the agent does not necessarily know the supervisor’s preferences. We formally prove the occurrence of collusion is more...

An optimizing representative firm pays efficiency wages to skilled workers to produce technological innovations, which are assumed to be of labor saving type, affecting negatively the hiring rate of unskilled workers. The results are: i) The efficiency wage of skilled workers is determined by...

In this paper, we introduce firm heterogeneity in the context of a model of non-compliance with minimum wage legislation. The introduction of heterogeneity in the ease with which firms can be monitored for non compliance allows us to show that non-compliance will persist in sectors which are...

Using the Principal-Agent-Supervisor paradigm, we examine in this paper how a tax collection agency changes optimal schemes in order to lessen the occurrence of bribery between the tax collector and the taxpayer. The Principal, who maximizes the expected net fiscal revenue, reacts by decreasing...

This paper studies a dynamic model with efficiency wages and adjustment costs associated with hiring and firing decisions. With linear adjustment costs, the optimal efficiency wage and employment are affected by the real interest rate and adjustment costs. When lumpy costs or convex adjustment...

This paper provides a socio-psychological theory of efficiency wage growth. The model blends agency theory with the Forced Savings hypothesis by assuming that firms set an increasing wage profile to minimize shirking costs, and that workers’ effort is positively related to the variation of...
