The paper evaluates some proposals for macroeconomic stabilization in an open economy, which take the form of simple rules. The first rule assigns monetary policy to inflation control and does not require fiscal intervention. The second rule adds fiscal control of a foreign wealth target to the...

Business cycles reflect changes over time in the amount of trade between individuals. In this paper we show that incorporating explicitly intra-temporal gains from trade between individuals into a macroeconomic model can provide new insight into the potential mechanisms driving economic...

This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response,...

We utilize an overlapping generations model with endogenous production and incomplete markets to quantify the distortionary costs associated with financing the increase in government expenditures directed to investments in the private sector in 2008 and 2009 (a.k.a. ‘the bailout’), and its...

This paper discusses the conditions under which currency unions would be desirable and viable. We discuss and present new empirical evidence concerning the operation of existing currency unions in federal states and among regional country groupings. In particular, we examine the traditional...

As a companion to a previous paper, monetary and fiscal policy are analyzed in (a) a small open economy and (b) a two-country world, where in addition to a fixed wage causing unemployment, countries now produce specialized products whose prices are fixed, causing excess supply. There are two...

This paper offers a critique of the UK government's Medium Term Financial Strategy from a policy optimization perspective. It argues that recent versions of the MTFS can be interpreted as representing the outcome of a policy optimization exercise, but that certain key aspects remain unclear....

This survey essay considers how rational expectations have changed our evaluation of monetary policy. In the first section, various underpinnings of the "Phillips curve" relation between inflation and output are reviewed. All are concluded to be products of particular institutional set-ups whose...

Leith and Wren-Lewis (2007) have shown that government debt is returned to its pre-shock level in a New Keynesian model under optimal discretionary policy. This has two important implications for monetary and fiscal policy. First, in a high-debt economy, it may be optimal for discretionary...
