We derive a very general ("Janus") money demand function, which reflects backward and forward-looking habit formation. This generality offers an explanation for the breakdown of money-demand functions and policy relevance of monetary aggregates. Integrating our Janus money demand into a...

The Solow condition is examined in an intertemporal model that blends the shirking and the turnover models of efficiency wages with managerial supervision. It is shown that the Solow condition does not hold when shirking and turnover costs are considered. The Solow condition can be a possible...

This paper analyses an overlapping generations model with absolute bequest motive. It is shown that the widely accepted criterion to verify dynamic efficiency does not apply to this case. In our model the social planner maximizes welfare by choosing a capital stock larger than the golden rule...

This paper investigates the relationship between inflation and output in the context of an economy facing persistent high inflation. By analyzing the case of Brazil, we find that inflation does not impact real output in the long run, but that in the short run there exists a negative effect from...

The paper discusses how the Peter and Dilbert Principles can occur and what are the consequences for a profit maximizing firm. A competence frontier is constructed as a linear combination of the maximum levels of technical and social skills that are difficult to measure and evaluate. The Peter...

The intertemporal substitution model of labor supply has been based on closed economy models. This paper studies the intertemporal substitution hypothesis in an open economy. It derives the long run labor supply as a function of the real wage, real interest rate and real exchange rate from a...

This paper studies the impact of wage and employment taxes in an intertemporal efficiency wage model. The cases with fixed, linear and quadratic adjustment costs associated with job creation are considered. In general, the model shows that an increase in the employment tax leads to an increase...
