In the classical macroeconomic models constructed by Lucas (1972, 1975) and Barro (1976), monetary aggregates are assumed to be generated by a logarithmic random walk. This specification implies that all monetary growth is (a) unanticipated and (b) permanent

Optimal monetary policy maximizes welfare, given frictions in the economic environment. Constructing a model with two sets of frictions - the Keynesian friction of costly price adjustment by imperfectly competitive firms and the Monetarist friction of costly exchange of wealth for goods - the...

Propositions about long run neutrality are at the heart of most macroeconomic models. Yet, since the 1970's when Lucas and Sargent presented powerful critiques of traditional neutrality tests, empirical researchers have made little progress on testing these propositions. In this paper we show...

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...

Optimal monetary policy maximizes the welfare of a representative agent, given frictions in the economic environment. Constructing a model with two sets of frictions -- costly price adjustment by imperfectly competitive firms and costly exchange of wealth for goods -- we find optimal monetary...
