This paper establishes the existence of equilibria for environments in which outside money is issued competitively. Such equilibria are typically believed not to exist because of a classic overissue problem: if money is valued in equilibrium, an issuer produces money until its value is driven to...

We show that Arrow-Debreu equilibria with countably additive prices in infinite-time economy under uncertainty can be implemented by trading infinitely-lived securities in complete sequential markets under two different portfolio feasibility constraints: wealth constraint, and essentially...

In inflation targeting (IT) regimes, the Monetary Authority announces an explicit objective, the target for inflation. However, other objectives that possibly conflict with the inflation goal are present, such as keeping output close to its potential level and the stability of financial markets....

This paper studies the time variation of the Federal Reserve’s inflation target between 1960 and 2004 using both macro and yield curve data. I estimate a New Keynesian dynamic stochastic general equilibrium model in which the inflation target follows a random-walk process. I compare estimation...

We determine optimal monetary policy under commitment in a forward-looking New Keynesian model when nominal interest rates are bounded below by zero. The lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear. A calibration to the U.S....

We examine the usefulness of the spreads between the e/p ratio of the S&P 500 index and the yields on 3-month and 10-year Treasury securities as indicators of future market conditions. We find that while spreads are not particularly useful in a regression framework, the extreme values of the...
