The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

Global and local methods are widely used in international macroeconomics to analyze incomplete-markets models. We study solutions for an endowment economy, an RBC model and a Sudden Stops model with an occasionally binding credit constraint. First-order, second-order, risky steady state and...

We study optimal macroprudential policy in a model in which unconventional shocks, in the form of news about future fundamentals and regime changes in world interest rates,interact with collateral constraints in driving the dynamics of financial crises. These shocks strengthen incentives to...

Collateral constraints widely used in models of financial crises feature a pecuniary externality: Agents do not internalize how borrowing decisions taken in "good times" affect collateral prices during a crisis. We show that agents in a competitive equilibrium borrow more than a financial...

The unconventional shocks and non-linear dynamics behind the high volatility of financial markets present a challenge for the implementation of macroprudential policy. This paper introduces two of these unconventional shocks, news shocks about future fundamentals and regime changes in global...

An implication of the quot;globalization hazardquot; hypothesis is that sudden stops could be prevented by offering foreign investors price guarantees on emerging markets assets. These guarantees create a tradeoff, however, because they weaken globalization hazard by creating international moral...

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 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...
