We extend the Baumol-Tobin cash inventory model to a dynamic environment, which allows for the possibility of withdrawing cash at random times at a low cost. This modification captures developments in withdrawal technology, such as the increasing diffusion of bank branches and ATM terminals. We...

Sargent (1999) warns that if policy makers’ views on the unemployment-inflation trade-off are driven by empirical correlations, rather than theory, disinflations (escapes from high to low inflation) may periodically occur but are not bound to last. This Paper asks how different inflation...

We provide algorithms to solve a linear-quadratic optimal control problem with commitment. By extending to the case of imperfect information a procedure outlined in Ljungqvist and Sargent (2002), we make the results of Svensson and Woodford (2000) easy to implement. We provide a Mat-lab package...

Advances in the transaction technology allow agents to economize on the cost of cash management. We argue that accounting for the impact of new transaction technologies on currency holding behaviour is important to obtain theoretically consistent estimates of the demand for money. We modify a...

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...

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...

Most monetary policy analyses assume an atomistic private sector, thereby ignoring strategic interactions between policy and wage-setting decisions. Yet, non-atomistic wage-setters are a key feature of several industrialized economies. We study the economic consequences of non-atomistic agents...

We consider an economy where the oil price, industrial production, and other macroeconomic variables fluctuate in response to a variety of fundamental shocks. We estimate the effects of different structural shocks using robust sign restrictions suggested by theory using US data for the 1973-2007...

The literature on monetary policy games establishes that policy makers' attempts to boost employment above the 'natural' rate are futile and result in an inflationary bias when wage setters have rational expectations and the policy maker cannot precommit. This implies that a variation of the...

This Paper characterizes endogenous monetary policy when policymakers are uncertain about the extent to which movements in output and inflation are due to changes in potential output or to cyclical demand and cost shocks. We refer to this informational limitation as the ‘information problem’...
