Standard theoretical arguments tell us that countries with relatively little capital benefit from financial integration as foreign capital flows in and speeds up the process of income convergence. We show in a calibrated neoclassical model that conventionally measured welfare gains from this...

Most trade is invoiced in very few currencies. Despite this, the Mundell-Fleming benchmark and its variants focus on pricing in the producer's currency or in local currency. We model instead a 'dominant currency paradigm' for small open economies characterized by three features: pricing in a...

We estimate the impact of the COVID-19 crisis on business failures among small and medium size enterprises (SMEs) in seventeen countries using a large representative firm-level database. We use a simple model of firm cost-minimization and measure each firm's liquidity shortfall during and after...

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...

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...

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 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...

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....

Financially closed economies insure themselves against current-account shocks using international reserves. We characterize the optimal management of reserves using an open-economy model of precautionary savings and emphasize several results. First, the welfare-based opportunity cost of reserves...

We present a model of the optimal level of international reserves for a small open economy that is vulnerable to sudden stops in capital flows. Reserves allow the country to smooth domestic absorption in response to sudden stops, but yield a lower return than the interest rate on the country''s...
