In this article we develop a model to analyze patent-protected R&D investment projects when there is (imperfect) competition in the development and marketing of the resulting product. The competitive interactions that occur substantially complicate the solution of the problem since the decision...

We evaluate the Friedman-Schwartz hypothesis that a more accommodative monetary policy could have greatly reduced the severity of the Great Depression. To do this, we first estimate a dynamic, general equilibrium model using data from the 1920s and 1930s. Although the model includes eight...

The key idea is that people are influenced by those inside their network, but not by...

This paper introduces a framework for analyzing the role of financial factors as a source of instability in small open economies. Our basic model is a dynamic open economy model with a tradeable good produced with capital and a country-specific factor. We also assume that firms face credit...

While empirical evidence finds only a weak relationship between nominal exchange rates and macroeconomic fundamentals, forex markets participants often attribute exchange rate movements to a macroeconomic variable. The variables that matter, however, appear to change over time and some variable...

This paper studies the implications of the circulation of interest bearing regional debt in a monetary union. Does the circulation of this debt have the same monetary implications as the printing of money by a central government? Or are the obligations of this debt simply backed by future...

We analyze the relationship between financial development and inter-industry resource allocation in the short- and long-run. We suggest that in the long-run, economies with high rates of financial development will devote relatively more resources to industries with a 'natural' reliance on...
