We examine global economic dynamics under infinite-horizon learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), we find that under normal monetary and fiscal policy the intended steady state is locally but...

We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead...

The microeconomic foundations provided by the 'disequilibrium' macro-modelling approach of Barro-Grossman-Malinvaud are used to compare the performance of government spending and taxation as instruments of fiscal demand management in achieving a welfare optimum. Spending is successively treated...

Monetary, fiscal and exchange intervention policy are examined in a symmetric, two-country, two-period model. Money wages are rigid in period one, causing unemployment. In each period there is a single world output, traded in a perfectly competitive world market. The exchange rate is flexible,...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

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...

Monetary and fiscal policy are introduced into a version of Hart's "Keynesian features" model of imperfect competition. Individuals' labour supply is exogenous, so, under perfect competition, output is always at the exogenous "full employment" level. Imperfect competition takes the form of...

This survey outlines the general lessons of the recent literature on imperfectly competitive macroeconomies for the theory of monetary and fiscal policy. A general framework is presented which encompasses most of the existing literature. Although money is of itself neutral in these models, the...

We consider inflation and government debt dynamics when monetary policy employs a global interest rate rule and private agents forecast using adaptive learning. Because of the zero lower bound on interest rates, active interest rate rules are known to imply the existence of a second, low...
