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 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...

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...

Motivated by the Chinese experience, we analyze a semi-open economy where the central bank has access to international capital markets, but the private sector has not. This enables the central bank to choose an interest rate different from the international rate. We examine the optimal policy of...

Two well-known, but seemingly contradictory, features of exchange rates are that they are close to a random walk while at the same time exchange rate changes are predictable by interest rate differentials. In this paper we investigate whether these two features of the data may in fact be...

Nominal rigidities due to menu costs have become a standard element in closed economy macroeconomic modelling. The 'New Open Economy Macroeconomics' literature has investigated the implications of nominal rigidities in an open economy context and found that the currency in which prices are set...

We develop a dynamic general equilibrium macroeconomic model where a proportion of firms are credit constrained due to asymmetric information. In general, a macroeconomic shock has additional effects created by a reallocation of funds between credit-constrained and unconstrained firms. We show,...

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...
