This paper models a dynamic scholar’s allocation of time between academia and professional activities outside academia, given the academic labor market and social interactions. The model shows how particularly in less developed countries business and political networks may have large negative...

When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation...

This paper modifies a standard model of law enforcement to allow for learning by doing. We incorporate the process of enforcement learning by assuming that the agency’s current marginal cost is a decreasing function of its past experience of detecting and convicting. The agency accumulates...

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 necesarily know the supervisor’s preferences.We formally prove the occurrence of collusion is more...

We propose a dynamic efficiency wage model with learning by doing. By taking into account the change inthe stock of workers’ knowledge, firms set efficiency wages such that the effort–wage elasticity is not in general equal to one.

Heterogeneous firms facing demand-induced price fluctuations imperfectly compete for heterogeneous workers. It is shown that unemployment may arise in equilibrium because of the combination of uncertainty on product price and mismatch between workers’ skills and firms’ job requirements.

The relationship between globalization and economic growth in the developing countries remains controversial. Liberals argue that globalization will lead to higher economic growth and prosperity. Skeptics contend the opposite, where globalization processes might lead to increased inequality and...

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...

Many empirical works addressed the nature of the relationship between economic growth and financial developments. Although these studies concede that they are interdependent, they have used single equations methods for estimation. In particular in the country specific studies the Granger...

We analyze possible targets for the French debt-to-GDP ratio with a small model. The role of the US and German GDP growth, prices of raw materials, ECB monetary policy, and domestic policy is analyzed in the debt dynamics. We find that external conditions, together with policies to stimulate...
