Should one think of zero nominal interest rates as an undesirable liquidity trap or as the desirable Friedman rule? I use three different frameworks to discuss this issue. First, I restate Cole and Kocherlakota's (1998) analysis of Friedman's rule: short run increases in the money stock -...

The main aim of this article is to investigate the sources of non- neutrality in policy games involving one or more trade unions. We use a simple set up in order to clearly expose the basic mechanisms that also work in more complex frameworks. We show that there are common roots in the...

Short 1-page review article of research by Mohsin Khan (IMF)on threshold effects in the relationship between inflation and growth and the possible intermediary role played by the financial system. Published in Economisch Statistische Berichten, 06-03-2003, p. 114 (in Dutch)

This paper re-examines the empirical evidence on the price puzzle and proposes a new theoretical interpretation. Using structural VARs and two different identification strategies based on zero restrictions and sign restrictions, we find that the positive response of prices to a monetary policy...

Money demand is probably one of the most extensively studied economic relationship in applied economics. While useful surveys of existing literature are available, much of the attention has focused on the US. However, a considerable number of papers have recently been produced dealing with the...

This paper generalizes the classical theory of economic policy developed by Tinbergen and Theil to a static LQ-strategic context between n players. We show how this generalized version of controllability can profitably be used to deal with policy ineffectiveness issues and Nash equilibrium...

We examine the response of a sticky-wage economy to various real and nominal shocks. In addition to variations in hours, we allow for an endogenous response in worker effort per hour. Despite wages being predetermined, the labor market clears through the effort margin. We find that the ability...

We examine the impact of wage stickiness when employment has an effort as well as hours dimension. Despite wages being predetermined, the labor market clears through the effort margin. Consequently, welfare costs of wage stickiness are potentially much, much smaller.

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. Therefore, the study of how the policymaker's credibility affects the outcome of an announced disinflation should not be dissociated from the analysis of the determinants of the frequency...
