In this paper we: (i) provide a model of endogenous risk intolerance and serve aggregate demand contractions following a large (non-financial) shock; and (ii) demonstrate the effectiveness of Large Scale Asset Purchases (LSAPs) in addressing these contractions. The key mechanism stems from...

We theoretically analyze the interactions between asset prices, nancial speculation, and macroeconomic outcomes when output is determined by aggregate demand. If the interest rate is constrained, a rise in the risk premium lowers asset prices and generates a demand recession. This reduces...

Should monetary policymakers raise interest rates during a boom to rein in financial excesses? We theoretically investigate this question using an aggregate demand model with asset price booms and financial speculation. In our model, monetary policy affects financial stability through its impact...

We provide a continuous-time "risk-centric" representation of the New Keynesian model, which we use to analyze the interactions between asset prices, financial speculation, and macroeconomic outcomes when output is determined by aggregate demand. In principle, interest rate policy is highly...

We build a model of emerging markets crises which features two types of collateral constraints. Firms in a domestic economy have limited borrowing capacity from international investors. They also have limited borrowing capacity with respect to each other. We study how the presence of and changes...

While there is still much disagreement on the causes underlying recent emerging markets' crises, one factor that most observers have agreed upon is that contracting "dollar" (foreign currency) denominated external debt - as opposed to domestic currency debt - created balance sheet mismatches...

Although internal policy mismanagements can be cited in most recent emerging market crises, they seldom acount fully for the severity of these crises. The reluctance of international investors to provide the resources that would limit the extent of the reversal, almost invariably plays a key...

Latin America has experienced deep transformations during the 1990s. In many countries of the region traditional imbalances have been largely abated, privatizations are widespread, openness of both trade and financial accounts has been largely accomplished, supervisory and enforcement...

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...
