We show that optimal monetary and fiscal policies are time consistent for a class of economies often used in applied work, economies appealing because they are consistent with the growth facts. We establish our results in two steps. We first show that for this class of economies, the Friedman...

Are optimal monetary and fiscal policies time consistent in a monetary economy? Yes, but if and only if under commitment the Friedman rule of setting nominal interest rates to zero is optimal. This result is of applied interest because the Friedman rule is optimal for the standard preferences...

This working paper examines a theoretical model in which an entrepreneur’s net worth affects his ability to finance current activity. Net worth, in turn, is determined by asset prices, which can be affected by monetary policy. In this environment, the central bank plays a welfare-improving...

The present paper studies optimal monetary policy when the representative agent assumption is abandoned and financial wealth heterogeneity across households is introduced. Incomplete markets make households incapable of perfectly insuring against interest rate and inflation risk, creating a...

We find conditions for the Friedman rule to be optimal in three standard models of money. These conditions are homotheticity and separability assumptions on preferences similar to those in the public finance literature on optimal uniform commodity taxation. We show that there is no connection...

A discussion of the circumstances under which interest rate rules are consistent with nominal determinacy in macroeconomic models.

What are the economic effects of an interest rate cut when an economy is in the midst of a financial crisis? Under what conditions will a cut stimulate output and employment, and raise welfare? Under which will it have the opposite effects? The authors answer these questions in a general class...

The authors analyze the restrictions necessary to ensure that the interest-rate policy rule used by the central bank does not introduce real indeterminacy into the economy. They conduct this analysis in a flexible price economy and a sticky price model that satisfies the natural rate hypothesis....

Benhabib, Schmitt-Grohe, and Uribe (2003) argue that if you relied solely on local analysis you would be led to believe that aggressive, backward-looking interest rate rules are sufficient for determinacy. But from the perspective of global analysis, backward-looking rules do not guarantee...
