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...

Can variations in the expected future return on a portfolio of sovereign bonds itself have real effects on a small open economy? We build a model where banks face a capital sufficiency requirement to demonstrate that news about a fall in the expected return on a portfolio of long bonds can lead...

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...

This paper presents a DGE model in which aggregate price level inertia is generated endogenously by the optimizing behaviour of price setting ?rms. All the usual sources of inertia are absent here ie., all fi?rms are simultaneously free to change their price once every period and face no...

This paper illustrates how the destruction of firm-specific organizational capital associated with changes in firm-level employment can influence the behavior of ag- gregate job flows, even in the presence of heterogeneity across rms and even in the absence of aggregate shocks. Our analysis...

This paper presents a DGE model in which aggregate price level inertia is generated endogenously by the optimizing behaviour of price setting firms. All the usual sources of inertia are absent here ie., all firms are simultaneously free to change their price once every period and face no...

The first-order condition (FOC) associated with labour in many dynamic general equilibrium models involves only current period variables. Residuals constructed from this FOC are inconsistent with aggregate US data in that they are very large and highly persistent. The persistence suggests that...

Aggregate corporate profits are highly volatile and procyclical. Most dynamic general equilibrium models of the business cycle cannot deliver these basic features of the data. We develop a model of the U.S. economy in which firms expend resources to create intangible capital (IC), which is an...
