A major unresolved issue in business cycle theory is the construction of an endogenous propagation mechanism capable of capturing the persistence displayed in the data. In this paper we explore the quantitative implications of one propagation mechanism: learning by doing. Estimation of the...

This appendix provides simulation results for consumption, invest- ment and hours series for the "full model" discussed in the paper. The graphs also plot the relevant data for the US.

Three well known facts that characterize exchange rate data are: (a) the high correlation between bilateral nominal and real exchange rates; (b) the high degree of persistence in real exchange rate movements; and (c) the high volatility of real exchange rates. This paper attempts a joint, albeit...

Most Real Business Cycle models have a hard time jointly explaining the twin facts of strongly pro-cyclical Solow residuals and extremely low correlations between wages and hours. We present a model that delivers both these results without using exogenous variation in total factor productivity...

This paper presents a general equilibrium model in which middlemen emerge to facilitate trade in an environment of idiosyncratic tastes and heterogeneous goods. The gains to the traders can be measured along three dimensions: the rate of production, the time preference losses generated by the...
