After decades of trial, error, and occasional regress the pieces of a successful Latin American economic model can be seen scattered among the leading economies of the region. The most traditional macroeconomic maladies of the emerging world - such as chronic fiscal imbalances and monetary...

Fluctuations of business activity in the United States clearly have their monetary and financial side, but these aspects of U.S. economic fluctuations exhibit few quantitative regularities that have persisted unchanged across spans of tine over which the nation's financial markets have...

A broad exploratory data analysis is conducted to assess the promise of a kind of model in which long-term asset prices change through time primarily due to consumption related changes in the rate of discount. Aggregate consumption data are used to infer ex-post marginal rates of substitution....

We propose a novel measure of risk perceptions: the price of volatile stocks (PVS_t), defined as the book-to-market ratio of low-volatility stocks minus the book-to-market ratio of high-volatility stocks. PVS_t is high when perceived risk directly measured from surveys and option prices is low....

This paper investigates how, in a heterogeneous agents model with financial frictions, idiosyncratic individual shocks interact with exogenous aggregate shocks to generate time-varying levels of leverage and endogenous aggregate risk. To do so, we show how such a model can be efficiently...

Historical data and model simulations support the following conclusion. Inflation is low during stock market booms, so that an interest rate rule that is too narrowly focused on inflation destabilizes asset markets and the broader economy. Adjustments to the interest rate rule can remove this...

An equilibrium model of financial crises driven by Irving Fisher's financial amplification mechanism features a pecuniary externality, because private agents do not internalize how the price of assets used for collateral respond to collective borrowing decisions, particularly when binding...

We develop a model of investment with financial constraints and use it to investigate the relation between investment and Tobin's q. A firm is financed partly by insiders, who control its assets, and partly by outside investors. When their wealth is scarce, insiders earn a rate of return higher...

The current account reversals, large recessions, and price collapses that define Sudden Stops contradict the predictions of a large class of models in which the current account is a vehicle for consumption smoothing and investment financing. This paper shows that the quantitative predictions of...
