We develop and estimate a structural model of inflation that allows for a fraction of firms that use a backward looking rule to set prices. The model nests the purely forward looking New Keynesian Phillips curve as a particular case. We use measures of arginal cost as the relevant determinant of...

Financial innovation challenges the foundations of monetary theory, and standard monetary theory has not been very successful at describing the history of U.S. inflation. Motivated by these observations, I ask: Can we understand the history of U.S. inflation using a framework that ignores...

It is an open question whether and how indexed wage contracts reduce welfare or raise average inflation. This paper analyzes the impact of indexed wage contracts on inflation and social welfare in a Barro-Gordon model with discretionary monetary policy by endogenizing social costs of indexation....

Mean dynamics govern convergence to rational expectations equilibria of self-referential systems under least squares learning. We highlight escape dynamics that propel away from a rational expectations equilibrium under fixed-gain recursive learning schemes. These learning schemes discount past...

This paper studies the relationship between inflation, output, money and interest rates in the euro area, using data spanning 1980 2000. The P* model is shown to have considerable empirical support. Thus, the price gap' or, equivalently, the real money gap' (the gap between current real balances...

This paper proposes a theory of supply shocks, or shifts in the short-run Phillips curve, based on relative-price changes and frictions in nominal price adjustment. When price adjustment is costly, firms adjust to large shocks but not to small shocks, and so large shocks have disproportionate...
