This paper shows that an analytical analysis of the determinacy properties of the New Keynesian model with both staggered wages and prices is possible, despite the high dimensional nature (4D) of this model, if it is appropriately reformulated in continuous time. Our analysis supports Galí's...

This article presents a group of exercises of level and growth decomposition of output per worker using cross-country data from 1970 to 2000. It is shown that in the early seventies factors of production (capital and education) were the main source of output dispersion across economies and that...

This paper develops a human-capital-based endogenous growth scenario in which an economy initially produces the agricultural good, characterized by diminishing returns to scale, then produces `traditional manufacturing' under constant-returns and finally produces `modern manufacturing' under...

In the 1980s there was an increase in cross-sectional wage inequality while simultaneously there was a decrease in the time series volatility of aggregate output. This paper argues that increased efficiency of the labor market may help explain both features of the data. Increases in labor market...

We examine a model in which the utility function has been engineered so that it is optimal for consumers to aim for a fixed target level of retirement resources. In this case, consumption displays excess sensitivity to current income as well as perfect old age insurance. In an overlapping...

I study repayment behavior for college graduates who borrow under the U.S. Federal Student Loan Program to finance higher education. I develop a dynamic model with uninsurable shocks to earnings and student loan rates that explains the repayment pattern in U.S. data: college graduates with lower...

This paper studies whether the out-of-sample forecasting performance of a dynamic stochastic general equilibrium (DSGE) model improves by taking its nonlinear rather than its linear approximation to the data. We address this question within a New Keynesian monetary economy, considering both...

This paper investigates the role of equity markets in the determination of money demand. Expected equity returns are found to be significant determinants of money demand in the long run. We also uncover a strong positive drift in the elasticity of money demand with respect to expected equity...

As long as workers do not value their leisure much, the Mortensen-Pissarides search and matching model implies that unemployment and job vacancies would be much less responsive to changes in labor productivity than what we observe in the business cycles of the Canadian labor market. These...
