Empirical studies have documented that the persistence of the gap between inflation and its trend declined after the Volcker disinflation. Previous research into the source of the decline has offered competing views while sidestepping the possibility of equilibrium indeterminacy. This paper...

This paper indicates a contradiction with respect to the optimal neutral policy rate between two seminal contributions on the implications of uncertain economic dynamics for optimal monetary policy. While Craine (1979) implies tighter policy, Söderström (2002) finds certainty equivalence. This...

The popular Calvo model with indexation (Christiano, Eichenbaum and Evans, 2005) and sticky information (Mankiw and Reis, 2002) model have guided much of the monetary policy discussion. The strength of these approaches is that they can explain the persistence of inflation. However, both of these...

This paper analyzes optimal monetary policy under precommitment in a state-dependent pricing (SDP) environment. Under SDP, monopolistically competitive firms are allowed to endogenously change the timing of price adjustments. I show that this endogenous timing of price adjustment alters the...

In an attempt to find out the degree of monetary non-neutrality in Nigeria we started from finding out the size of price rigidity in the country. Computation with Ball and Romer method showed that price rigidity is optimal decision for firms in Nigeria only when the menu cost is well above 2.28%...

Mortgage loans are a striking example of a persistent nominal rigidity. As a result, under incomplete markets, monetary policy affects decisions through the cost of new mortgage borrowing and the value of payments on outstanding debt. Observed debt levels and payment to income ratios suggest the...

We study Ramsey monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find that in contrast with the standard NK model, the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government...

Monetary policy affects the degree of strategic complementarity in firms' pricing decisions if it responds to the aggregate price level. In normal times, when monopolistic competitive firms increase their prices, the central bank raises interest rates, which lowers consumption demand and creates...

In the Eurozone price stickiness differs among countries. I explore its consequences on the optimal rate of inflation in a two-country model. On the one hand, with local currencies an inflation tax is partly imposed on the foreign country, so it creates incentives to inflate. On the other hand,...
