We develop a quantitative equilibrium model of financial crises to assess the interaction between ex-post interventions in credit markets and the buildup of risk ex ante. During a systemic crisis, bailouts relax balance sheet constraints and mitigate the severity of the recession. Ex ante, the...

The macro-economic and micro-economic evidences makes a persuasive case for cities as important centers for productive efficiency, innnovation, and economic growth. For cities to achieve their full economic potential, however, complementary public services are required. This paper reviews the...

In Caballero and Simsek (2018), we develop a model of fickle capital flows and show that, when countries are similar, international flows create global liquidity and mitigate crises despite their fickleness. In this paper, we focus on the asymmetric situation of Emerging Markets (EM) exchanging...

We analyze the impact of technology on production and trade in services, focusing on the foreign exchange market. We identify exogenous technological changes by the connection of countries to submarine fiber-optic cables used for electronic trading, but which were not laid for purposes related...
