A series of models are developed in which international trade is modelled as a two-stage game between firms in two countries. At the first stage firms choose their productive capacity. At the second stage different types of market game are played. The most interesting case is that in which firms...

The purpose of this paper is to provide a simple model which illuminates the interdependence between primary commodity prices and the rest of the economy. We study the role of commodity prices in a disinflation program, the role of commodity prices in determining whether or not a fiscal...

Recent empirical work indicates that, in a variety of financial markets, both conditional expectations and conditional variances of asset returns are time-varying. The purpose of this paper is to determine whether these joint fluctuations of conditional first and second moments are consistent...

This paper reviews three problems of the world economy since the collapse of the Bretton Woods system; an unreliable price mechanism, spending imbalances between countries, and increased technological competition. It argues that the third phenomenon is the most fundamental and creates potential...

Swedish wives' market earnings contribute 39% of the net family earnings of couples living together. German wives contribute 12%. This paper employs Swedish and German micro data on earnings and personal characteristics of couples. After tax earnings are simulated, under both the tax system of...

This paper develops a model of equilibrium in the market for loans. It focuses on the effects on equilibrium of (i) differences in the liability of the lender and the borrower for losses; and (ii) differences in the information available to the lender. We examine the different types of...

It is argued that trigger mechanisms cannot support reputation if voters are atomistic and have access to good information about party preferences. Therefore the choice for a party lies between precommitment, enforced by penalties, and discretion. The paper uses a model of Labor and Conservative...

The paper presents a model of 'high-low search' under uncertainty, in which a 'conservative' firm 'searches' for an unknown product demand by making a sequence of production decisions. After each production decision and the concomitant sales, the firm infers whether its supply is 'too high' or...

The paper surveys recent analyses of rising unemployment in Europe based on the concept of the natural rate. It argues that there is a continuity of analysis from the classics through Keynes to these more recent approaches. Theories of efficiency wages, hysteresis, and insiders/outsiders are...

The paper develops a model of family size decisions in which couples choose explicitly a combination of mother's time and purchased child care (e.g. childminders, nannies) for the care and rearing of children. The theoretical model implies that the impact of the mother's wage on her completed...
