In a canonical staggered pricing model, monetary discretion leads to multiple private sector equilibria. The basis for multiplicity is a form of policy complementarity. Specifically, prices set in the current period embed expectations about future policy, and actual future policy responds to...

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 popular press would lead us to believe that during the stock market boom of the 1990s just about everyone was buying and selling bonds every day. In fact, evidence shows that most households make only infrequent changes to their investment portfolios. "In The Role of Market Segmented Markets...

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 - we...

In a canonical staggered pricing model, monetary discretion leads to multiple private sector equilibria. The basis for multiplicity is a form of policy complementarity. Specifically, prices set in the current period embed expectations about future policy, and actual future policy responds to...

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