This paper interprets contagion effects as an increase in the volatility of aggregate shocks impinging on the domestic economy. The implications of this approach are analyzed in a model with two types of credit market imperfections: domestic banks borrow at a premium on world capital markets,...

This paper examines the effect of skill-biased technological change on the structure of wages, the composition of employment and the level of unemployment in a two-sector economy with a heterogenous work force. Efficiency wage considerations and minimum wage legislation lead to labor market...

This paper examines some recent techniques designed to draw inferences about the credibility of changes in macroeconomic policy regimes. An alternative two-step approach, based on the decomposition between permanent and transitory components of a "credibility variable" is proposed. The...

The paper develops and tests a model of a developing economy that incorporates trade and capital restrictions, illegal transactions, a parallel foreign exchange market, currency substitution features, and forward-looking rational expectations. Temporary expansionary demand policies are...

The paper analyzes the role of labor market segmentation and relative wage rigidity in the transmission process of macroeconomic shocks in a two-sector optimizing model of a small open economy. The analysis is first conducted in the context of perfect intersectoral labor mobility. The discussion...

This paper analyzes the macroeconomic effects of fiscal and labor market policies in developing countries. The basic framework considers a small open economy with a large informal production sector and a heterogeneous work force. The labor market is segmented as a result of efficiency...

This paper examines whether price controls may enhance the credibility of a disinflation program, using a framework in which agents behave strategically. The analysis indicates that a partial price freeze is not fully credible, and may result in inflation inertia. The authorities may be able to...

This paper examines the behavior of real interest rates in exchange-rate based stabilization programs. The analysis is based on a model with imperfect capital mobility and optimizing agents. A permanent reduction in the devaluation rate is first shown to have an ambiguous effect on real interest...

The paper examines the role of credibility in the conduct of exchange rate policy in developing countries, The analysis is based on a model in which policymakers are concerned about inflation and external competitiveness. Price setters in the nontraded goods sector of the economy adjust prices...

This paper studies the interactions between electoral considerations and the imposition of price controls by opportunistic policymakers. The analysis shows that a policy cycle emerges in which price controls are imposed in periods leading to the election, and removed immediately afterwards. The...
