Fashion is a popular style of behavior at a given time or place. In this paper we model fashion as a dynamic phenomenon, characterized by fragility of mass behvior and life cycles. Conformity of behavior is generated by a consumption externality, while the typical intertemporal aspects of...

We develop an economic theory of tolerance where styles of behaviour are invested with symbolic value. Value systems are endogenous and taught by parents to their children. In conjunction with actual behaviour, value systems determine the esteem enjoyed by individuals. Intolerant individuals...

This paper presents a theory of the maturity of international sovereign debt and derives its implications for the reform of the international financial architecture. It presents a general equilibrium model in which the need to roll over external debt disciplines the policies of debtor countries...

Defending a government’s exchange-rate commitment with active interest rate policy is not an option in the Krugman-Flood-Garber (KFG) model of speculative attacks. In that model, the interest rate is the passive reflection of currency-depreciation expectations. In this paper we show how to...

This paper considers how an international lender of last resort (LOLR) can prevent self-fulfilling banking and currency crises in emerging economies. We compare two different arrangements: one in which the international LOLR injects liquidity into international financial markets, and one in...

This paper explores the hypothesis that the dollarization of liabilities in emerging market economies is the result of a lack of monetary credibility. I present a model in which firms choose the currency composition of their debts so as to minimize their probability of default. Decreasing...

The link between monetary policy and asset price movements has been of perennial interest to policymakers. In this paper, we consider the potential case for preemptive monetary restrictions when asset price reversals can have serious effects on real output. First, we present some stylized facts...

An independent central bank can manage its balance sheet and its capital so as to commit itself to a depreciation of its currency and an exchange rate peg. This way, the central bank can implement the optimal escape from a liquidity trap, which involves a commitment to higher future inflation....

Using a simple model of international lending, we show that as long as the IMF lends at an actuarially fair interest rate and debtor governments maximize the welfare of their taxpayers, any changes in policy effort, capital flows, or borrowing costs in response to IMF crisis lending are...
