This paper provides evidence for a low frequency relationship between unemployment, inflation and the nominal interest rate. I show that in the United States from 1959.1 to 1991.3, the unemployment rate, the inflation rate and the federal funds rate can be modelled as non stationary time series...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

This paper examines how supply-side policies may play a role in fighting a low aggregate demand that traps an economy at the zero lower bound (ZLB) of nominal interest rates. Future increases in productivity or reductions in mark-ups triggered by supply-side policies generate a wealth effect...

The purpose of this paper is to survey and re-interpret the extensive literature that tried to explain both the depth of the great depression in Europe and the delay of recovery as a failure to coordinate economic policies. Europe could not exploit her vast economic potential after 1918, because...

We study the optimal monetary policy in a two-country open-economy model under two monetary arrangements: (a) multiple currencies controlled by independent policy-makers; (b) common currencies controlled by a centralized policy-maker. Our findings suggest that: (i) Monetary policy competition...

A monetary union is modelled as a technology that makes surprise devaluations impossible but requires voluntarily participating countries to follow the same monetary policy. It is shown that for low discount factors and sufficiently correlated shocks welfare in the union is higher than that...

This chapter highlights the problems that structural methods and SVAR approaches have when estimating DSGE models and examining their ability to capture important features of the data. We show that structural methods are subject to severe identification problems due, in large part, to the nature...

It has been argued that the inflationary bias of discretionary monetary policy can be eliminated, and welfare maximized, by the appointment of a central banker who does not care at all about inflation (a 'populist central banker'). We show that this result hinges crucially on the assumption that...

There is a small, but growing, economics literature on the importance and effects of having monetary policy made by a committee, rather than by an individual. Complimenting this is an older and larger body of literature on groups in the other social sciences, particular in social psychology....

This paper explores the influence of wage and price staggering on monetary persistence. We show that, for plausible parameter values, wage and price staggering are highly complementary in generating monetary persistence. We do so by proposing the new measure "quantitative persistence," after...
