This paper proposes a simple theory of a system of cities that decomposes the determinants of the city size distribution into three main components: efficiency, amenities, and frictions. Higher efficiency and better amenities lead to larger cities, but also to greater frictions through...

We model the motives for residents of a country to hold foreign assets, including the precautionary motive that has been omitted from much previous literature as intractable. Our model captures many of the principal insights from the existing specialized literature on the precautionary motive,...

A fixed-exchange-rate system is characterized by two pillars: monetary policy coordination and foreign exchange reserves. This paper concentrates on the fluctuation of foreign exchange reserves by taking monetary policy coordination as given: the sustainability of the fixed exchange rate regime...

We examine the determinants of external crises, focusing on the role of foreign liabilities and their composition. Using a variety of statistical tools and comprehensive data spanning 1970-2011, we find that the ratio of net foreign liabilities to GDP is a significant crisis predictor. This is...

Has the US dollar delivered the benefits that the rest of the world is expecting from its holdings of international liquidity? US government debt has been liquid and safe, and it is supplied in sufficient quantity. But it has given a low return to the countries that accumulated the most...

Exploiting the Japanese banking crisis as a laboratory, we provide firm-level evidence on the real effects of bank bailouts. Government recapitalizations result in positive abnormal returns for the clients of recapitalized banks. After recapitalizations, banks extend larger loans to their...

A key precursor of twentieth-century financial crises in emerging and advanced economies alike was the rapid buildup of leverage. Those emerging economies that avoided leverage booms during the 2000s also were most likely to avoid the worst effects of the twenty-first century’s first global...

Central bank policy suffers from time-inconsistency when facing a banking crisis: A bailout is optimal ex post but ex ante it should be limited to control moral hazard. Dollarization provides a credible commitment not to help at the cost of not helping even when it would be ex ante optimal to do...

This Paper explores the implications of different strategies for financing the fiscal costs of twin crises in inflation and depreciation rates. We use a first-generation type model of speculative attacks which has four key features: (i) the crisis is triggered by prospective deficits: (ii) there...

This Paper addresses two questions: (i) how do governments actually pay for the fiscal costs associated with currency crises; and (ii) what are the implications of different financing methods for post-crisis rates of inflation and depreciation? We study these questions using a general...
