How does the optimal design of macroprudential capital controls depend on the ability of some agents to circumvent regulation? To address this question, we study the interaction between a regulated and an unregulated sphere in a model economy where pecuniary externalities calls for ex-ante...

El desarrollo económico, la evolución de la ciencia y la tecnología, la explosión demográfica, la “cultura” informatizada, las libertades democráticas y la corrupción, han provocado una crisis moral sin precedentes, una revolución del concepto que tiene el hombre de sí mismo, de lo...

This paper investigates whether the international globalization of financial markets allows for significant cross-country risk-sharing at the business cycle frequency. We find that cross-country risk-sharing is still limited and this is unlikely to be the result of financial frictions that limit...

Most emerging markets do not borrow much internationally in their own currency, although doing that has been argued as an attractive insurance mechanism. This phenomenon, commonly labeled"the original sin", has mostly been interpreted as evidence of the countries'inability to borrow in domestic...

A long-standing puzzle of international capital flows is why countries hold large amount of external debt and foreign reserves at the same time. To address this puzzle, we propose a sovereign default model where the government decides jointly over the accumulation of long-duration bonds and...

This paper develops a non-linear DSGE model to assess the interaction between ex-post interventions in credit markets and the build-up of risk ex ante. During a systemic crisis, bailouts to the financial sector relax balance sheet constraints and accelerate the economic recovery. Ex ante, the...

Credit constraints that link a private agent's debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to ``overborrow." The externality arises because agents fail to internalize the...

This paper studies overborrowing, financial crises and macro-prudential policy in an equilibrium model of business cycles and asset prices with collateral constraints. Agents in a decentralized competitive equilibrium do not internalize the negative effects of asset fire-sales on the value of...

Two striking facts about international capital flows in emerging economies motivate this paper: (1) Governments hold large amounts of international reserves, for which they obtain a return lower than their borrowing cost. (2) Purchases of domestic assets by nonresidents and purchases of foreign...
