This paper focuses on some of the macroeconomic risks that lie ahead for Latin America. The discussion is informed by my work on crises and capital flows and their macroeconomic consequences. The trends and initial conditions that allowed the region to weather the global economic storm of...

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...

In this note, we attempt to place the question of how we got to the global financial crisis that began as the US Subprime debacle in the summer of 2007 in the context of an international and historical comparative setting. It is of some poignancy that the “we” here refers to the wealthiest...

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...
