The recent East Asian crisis has highlighted the relationship between financial development and output volatility. In this essay we develop a simple model of a small open economy producing a tradeable good using a non-tradeable input and where firms access to borrowings and investment depends on...

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 one tradeable and one non-tradeable good with the non-tradeable being an input to the production of the...

This paper analyzes the optimal interest rate policy in currency crises. Firms are credit constrained and have debt in domestic and foreign currency, a situation that may easily lead to a currency crisis. An interest rate increase has an ambiguous effect on firms since it both makes more...

This paper presents a simple model of currency crises which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities. The possibility of multiple equilibria, including a "currency crisis" equilibrium with low output and a...

This paper presents a general equilibrium currency crisis model of the "third generation", in which the possibility of currency crises is driven by the interplay between private firms' credit-constraints and nominal price rigidities. Despite our emphasis on microfoundations, the model remains...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between dirty (internal combustion engine) and clean (e.g. electric and hybrid) patents across 80 countries over several decades. We show that firms...
