In a New Keynesian model with the BGG accelerator and risk shocks, we show that violations of Tinbergen's Rule and strategic interaction between economic authorities undermine the effectiveness of monetary and financial policies. Separate monetary and financial policy rules produce higher...

Violations of Tinbergen's Rule and strategic interaction undermine monetary and financial policies significantly in a New Keynesian model with the Bernanke-Gertler accelerator. Welfare costs of risk shocks are large because of efficiency losses and income effects of costly monitoring, but they...

What are the stylized facts that characterize the dynamics of credit booms and the associated fluctuations in macro-economic aggregates? This paper answers this question by applying a method proposed in our earlier work for measuring and identifying credit booms to data for 61 emerging and...

We study the short- and long-run effects of financial integration in emerging economies using a two-sector model with a collateral constraint on external debt and trading costs incurred by foreign investors. The probability of a financial crisis displays overshooting: It rises sharply initially...

In the 1990s, Sudden Stops in emerging markets were a harbinger of the 2008 global financial crisis. During these Sudden Stops, countries lost access to credit, which caused abrupt current account reversals, and suffered severe recessions. This article reviews a class of models that yield...

The European debt crisis shares features of the historical episodes of outright default on domestic public debt identified by Reinhart and Rogoff (2008) as a forgotten research subject. This paper proposes a theory of domestic sovereign default in which a government chooses debt and default...

Quantitative analysis of a New Keynesian model with the Bernanke-Gertler accelerator and risk shocks shows that violations of Tinbergen's Rule and strategic interaction between policymaking authorities undermine significantly the effectiveness of monetary and financial policies. Separate...

This paper shows that the quantitative predictions of an equilibrium asset pricing model with financial frictions are consistent with the large consumption and current-account reversals and asset-price collapses observed in the "Sudden Stops" of emerging markets crises. Margin requirements set a...

The hypothesis that Sudden Stops to capital inflows in emerging economies may be caused by global capital market frictions, such as collateral constraints and trading costs, suggests that Sudden Stops could be prevented by offering price guarantees on the emerging-markets asset class. Providing...
