In a plain-vanilla New Keynesian model with two-period staggered price-setting, discretionary monetary policy leads to multiple equilibria. Complementarity between pricing decisions of forward-looking firms underlies the multiplicity, which is intrinsically dynamic in nature. At each point in...

This paper analyzes the interaction of money and the price level with a business cycle that is fully real in origin, adopting a view which differs sharply from traditional theories that assign a significant causal influence to monetary movements. The theoretical analysis focuses on a banking...

This paper studies the economic role of financial institutions in economies where agents' incomes are subject to privately observable, idiosyncratic random events. The information structure precludes conventional insurance arrangements. However, a financial institution -- perhaps best viewed as...

Rational expectations theory instructs empirical researchers to uncover the values of 'deep' structural parameters of preferences and technology rather than the parameters of decision rules that confound these structural parameters with those of forecasting equations. This paper reevaluates one...

Can nominal contracts make a difference for the neutrality of money if these arise endogenously in general equilibrium? This paper utilizes aversion of Lucas's seminal equilibrium business cycle theory to address this question. However, we depart from Lucas in assuming that (1) agents have...

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...

This paper explores the implications of rational expectations and the aggregate supply theory advanced by Lucas (1973) for analysis of optimal monetary policy under uncertainty along the lines of Poole (1970), returning to a topic initially treated by Sargent and Wallace (1975). Not...

Time-separability of utility means that past work and consumption do not influence current and future tastes. This form of preferences does not restrict the size of intertemporal-substitution effects--notably, we can still have a strong response of labor supply to temporary changes in wages....

This paper analyzes the interaction of money and the price level with a business cycle that is fully real in origin, adopting a view which differs sharply from traditional theories that assign a significant causal influence to monetary movements. The theoretical analysis focuses on a banking...

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...
