Conventional wisdom suggests that medium-term money neutrality imposes strong limitations on the effects of monetary policy. The point of this paper is that models with medium- and long-term money neutrality are prone to generate non-existence of equilibria at the effective lower bound (ELB) on...

Empirical evidence suggests that as much as 1/3 of the U.S. business cycle is due to nominal shocks. We calibrate a multi-sector menu cost model using new evidence on the cross-sectional distribution of the frequency and size of price changes in the U.S. economy. We augment the model to...

We present estimates of monetary non-neutrality based on evidence from high-frequency responses of real interest rates, expected inflation, and expected output growth. Our identifying assumption is that unexpected changes in interest rates in a 30-minute window surrounding scheduled Federal...

We model dividend and consumption growth rates as containing a small long-run predictable component and economic uncertainty (i.e., growth rate volatility) as being time-varying. The magnitudes of the predictable variation and changing volatility in growth rates, as in the data, are quite small....

I translate familiar concepts of discrete-time time-series to contnuous-time equivalent. I cover lag operators, ARMA models, the relation between levels and differences, integration and cointegration, and the Hansen-Sargent prediction formulas

The Mussa (1986) puzzle is the observation of a sharp and simultaneous increase in the volatility of both nominal and real exchange rates following the end of the Bretton Woods System of pegged exchange rates in 1973. It is commonly viewed as a central piece of evidence in favor of monetary...

I study a general equilibrium menu cost model with a continuum of sectors, idiosyncratic and aggregate shocks, and the novel feature that each sector consists of strategically engaged firms. Compared to an economy with monopolistically competitive sectors--separately parameterized to match the...

This paper examines the interaction between the financial and real sectors of the economy within the framework of a stochastic, rational expectation model that distinguishes between inside and outside money. The model also can be used to study the impact of variations in the degree of...

This paper examines the implications of an endogenous money supply for the perceived(by econometricians) and actual nonneutrality of money in rational expectations models of the class put forward by Lucas (1972, 1973) and Barro(1976, 1980) that stress incomplete information. First,if there is...
