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...

A three-good, stochastic intertemporal equilibrium model of a small open economy is used to examine the link between terms of trade and business cycles. Equilibrium co-movements of model economies representing industrial and developing countries are computed and compared with the stylized facts...

A dynamic stochastic equilibrium model of a small open economy is used to quantify the macroeconomic effects of introducing capital controls to stabilize the balance of trade. This model focuses on the role of international trade and foreign debt as instruments that help smooth consumption in...

We study the characteristics of credit booms in emerging and industrial economies. Macro data show a systematic relationship between credit booms and economic expansions, rising asset prices, real appreciations and widening external deficits. Micro data show a strong association between credit...

A methodology for computing effective average tax rates on factor incomes and consumption using OECD data from national accounts and revenue statistics is described and applied to construct time series of tax rates for the group of seven largest industrialized countries. These tax rates are...

Financial globalization was off to a rocky start in emerging economies hit by Sudden Stops in the 1990s. The surge in foreign reserves since then is viewed as a New Merchantilism in which reserves are a war-chest for defense against Sudden Stops. We conduct a quantitative assessment of this...

This paper shows that the dominant view that the high variability of real exchange rates is due to movements in exchange rate-adjusted prices of tradable goods does not hold for Mexican data for periods with a managed exchange rate. The relative price of nontradables accounts for up to 70...

This paper looks at fiscal solvency and public debt sustainability in both emerging market and advanced countries. Evidence of fiscal solvency, in the form of a robust positive conditional relationship between public debt and the primary fiscal balance, is established in both groups of...

Emerging markets business cycle models treat default risk as part of an exogenous interest rate on working capital, while sovereign default models treat income fluctuations as an exogenous endowment process with ad-noc default costs. We propose instead a general equilibrium model of both...

Uncertainty about the riskiness of new financial products was an important factor behind the U.S. credit crisis. We show that a boom-bust cycle in debt, asset prices and consumption characterizes the equilibrium dynamics of a model with a collateral constraint in which agents learn "by...
