The paper argues that Emerging Market economies (EMs) face financial vulnerabilities that weaken the effectiveness of a domestic Lender of Last Resort (LOLR). As a result, monetary policy is inextricably linked to the state of the credit market. In particular, the central bank should be ready to...

The paper examines the robustness of Interest Rate Rules, IRRs, in the context of an imperfectly credible stabilization program, closely following the format of much of the literature in open-economy models, e.g., Calvo and Végh (1993 and 1999). A basic result is that IRRs, like Exchange Rate...

Fluctuations in commodity prices are often associated with macroeconomic volatility. But not all nations are created equal in this regard. The macro response to commodity booms and busts depends both on the structural characteristics of the economy and on the policy framework that is in place....

I analyze whether countries with flexible exchange rates are able to pursue an independent monetary policy, as suggested by traditional theory. I use data for three Latin American countries with flexible exchange rates, inflation targeting, and capital mobility – Chile, Colombia and Mexico –...

We analyze the optimal Taylor rule in a standard New Keynesian model. If the central bank can observe the output gap and the inflation rate without error, then it is typically optimal to respond infinitely strongly to observed deviations from the central bank's targets. If it observes inflation...

We develop a model of the market for federal funds that explicitly accounts for its two distinctive features: banks have to search for a suitable counterparty, and once they meet, both parties negotiate the size of the loan and the repayment. The theory is used to answer a number of positive and...

In the summer of 2010, the Federal Reserve's and the Swedish Riksbank's inflation forecasts were below the former's mandate-consistent rate and the latter's target, respectively, and their unemployment forecasts were above sustainable rates. Given the mandates of the Federal Reserve and the...

A standard statistical perspective on the U.S. Great Inflation is that it involves an increase in the stochastic trend rate of inflation, defined as the long-term forecast of inflation at each point in time. That perspective receives support from two sources: the behavior of long-term interest...

We first document a large secular shift in the estimated response of the entire term structure of interest rates to inflation and output in the United States. The shift occurred in the early 1980s. We then derive an equation that links these responses to the coefficients of the central bank's...

Financial systems are inherently fragile because of the very function which makes them valuable: liquidity transformation. Regulatory reforms can strengthen the financial system and decrease the risk of liquidity crises, but they cannot eliminate it completely. This leaves monetary policy with a...
