The authors consider inflation and government debt dynamics when monetary policy employs a global interest rate rule and private agents forecast using adaptive learning. Because of the zero lower bound on interest rates, active interest rate rules are known to imply the existence of a second,...

We present a simple model that can account for the main features of recent financial crises in emerging markets. The international illiquidity of the domestic financial system is at the center of the problem. Illiquid banks are a necessary and a sufficient condition for financial crises to...

The result of Benhabib, Schmitt-Grohé, and Uribe (2001) is powerful because it relies only on three rather natural conditions: the Fisher equation, the convex Taylor rule, and the lower bound of the nominal interest rate. Their result is striking because the paper reveals the peril of the...

A country's financial system is internationally illiquid if its potential short-term obligations in foreign currency exceed the amount of foreign currency it can have access to in short notice. This condition may be necessary and sufficient for financial crises and/or exchange rate collapses...

We build a model of financial sector illiquidity in an open economy. Illiquidity is defined as a situation in which a country's consolidated financial system has potential short-term obligations that exceed the amount of foreign currency available on short notice. We show that illiquidity is key...

This paper develops a model in which information losses may be an important part of the cost of an OTC derivatives dealer's failure. A dealer failure forces solvent counterparties of a failed dealer to seek replacement hedges with other dealers. However, by forcing good firms into the...

Firms with private information about the outcomes of production under uncertainty may face capital (liquidity) constraints that prevent them from attaining efficient levels of investment in a world with costly and/or imperfect monitoring. As an alternative, we examine the efficiency of a simple...

What happens when liquidity increases in credit markets and more funds are channeled from borrowers to lenders? We examine this question in a general equilibrium model where financial matchmakers help borrowers (firms) and lenders (households) search out and negotiate profitable matches and...

Galí (2014) showed that a monetary policy rule that raises interest rates in response to bubbles can paradoxically lead to larger bubbles. This comment shows that a central bank that wants to dampen bubbles can always do so by raising interest rates aggressively enough. This result is different...

During the recent financial crisis, the Federal Reserve implemented a series of extraordinary and unconventional policies to alleviate the impact of the crisis on financial markets and the economy. In this paper, we examine the effects of these policies on broad financial market conditions,...
