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...

In this Paper we carry over a static version of a New Keynesian Macromodel a la Clarida Gali Gertler (1999) to a monetary union. We will show in particular that a harmonious functioning of a monetary union critically depends on the correlation of shocks that hit the currency area. Additionally a...

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...

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,...

A monetary overlapping generations model with oligopolistic imperfect competition is constructed. In general, output and employment are below their full employment levels. Three alternative expectations hypotheses are used - 'adaptive', 'monetarist' and 'pure rational' - all of which ensure no...

Understanding the features and the determinants of individual price setting behaviour is important for the formulation of monetary policy. These behavioural mechanisms play a fundamental role in influencing the characteristics of aggregate inflation and in determining how monetary policy affects...

The paper discusses the strong output decline in the countries of Central and Eastern Europe. It starts from the puzzling observation that the former CSFR, Hungary and Poland experienced a relatively similar decline in output in spite of completely different stabilization and transformation...

The first part of the paper analyzes the inflationary risks associated with price liberalization, the welfare costs of inflation and the difficulties of East European central banks in pursuing non-inflationary policies. The main obstacles are the low credibility of stabilization policies and a...
