We present a monetary model in the presence of segmented asset markets that im- plies a persistent fall in interest rates after a once and for all increase in liquidity. The gradual propagation mechanism produced by our model is novel in the literature. We provide an analytical characterization...

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’...

The empirical evidence on rational inattention lags far behind the theoretical developments: micro evidence on the most immediate consequence of observation costs - the infrequent observation of state variables - is not available in standard datasets. We contribute to filling the gap with two...

We study the price setting problem of a firm in the presence of both observation and menu costs. In this problem the firm optimally decides when to collect costly information on the adequacy of its price, an activity which we refer to as a price ``review''. Upon each review, the firm chooses...

This paper analyzes the macroeconomic consequences of the establishment of a monetary union in the presence of unionized labour markets. It is shown that the effects of the formation of a monetary union depend on several labour market features, such as the degree of centralization of wage...
