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...

It is often claimed that the demand externality created by imperfectly competitive markets can provide an analytical basis for Keynesian fiscal policy prescriptions. Here this demand externality is embedded in a model where saving and employment are determined by optimizing choices in an...

We explore the incentives for governments to cooperate by expanding expenditure. We model three countries, of which two are in a monetary union (the EU). The labour markets of both EU countries are unionized, and there is involuntary unemployment. We use a general model of bargaining, and...

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...

This paper considers the effects of monetary and fiscal policies in an optimizing model with capital accumulation and finite lives. An increase in monetary growth is no longer superneutral in a money-capital economy, but leads to a reduction in the real interest rate and increases in the capital...

A new theory of price determination suggests that if primary surpluses are independent of the level of debt, the price level has to ‘jump’ to assure fiscal solvency. In this regime (which we call fiscal dominant), monetary policy has to work through seignorage to control the price level. If,...

We analyze a two-country zone facing a joint inflationary shock and responding with coordinated and uncoordinated monetary and fiscal policies. We show that the standard presumption that the absence of coordination results in an excessive exchange rate appreciation of the zone with respect to...

This paper assesses how monetary authorities behave and how they interact. Pooled data for the 15 members of the European Union except Luxembourg and five other OECD countries serves to answer these questions. Three basic conclusions emerge. First, fiscal policy responds to the ratio of public...

This paper considers fiscal and monetary policy in a short-run static macroeconomic model. There are two objectives, control of inflation and control over the growth of national wealth, and a third outcome of importance, a high level of employment. There are two instruments, monetary policy (the...

The paper studies an idealized gold standard in a two-country setting. Unless national policies for domestic credit expansion (dce) are flexible enough to offset the effect of money demand shocks on international gold reserves, the gold standard collapses with certainty in finite time through a...
