A stylized model of the Chinese economy is developed with three production sectors: agriculture, non-traded industrial goods, and industrial exports. The state purchases food from farmers by dual-track pricing; urban food sales are subsidized through ration coupons. Marginal prices clear markets...

An economy consists of many duopolistic markets. Firms must earn normal profits in the long run if they are to survive. Normal profits are interpreted as the long-run limit of average profits in the whole economy. We adopt the aspiration based model of firm behaviour, and link it to the economy...

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 three-sector macromodel of China’s economy is developed, in which the activity of state-owned enterprises (SOEs) is constrained by the state-imposed credit plan for working capital. Our analysis indicates the weakness of credit control and interest rate variation as anti-inflationary tools....

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 a three sector small open economy, with a monopolistic non-traded sector, a competitive traded good sector, and a capital goods sector. In both the consumer good sectors, there are enterprise unions that bargain sequentially over wages and employment as in Manning (1987). This...

Waiting-time targets are frequently used by policy makers in the healthcare sector to monitor provider's performance. Such targets are based on the distribution of the patients on the list. We compare and link such distribution with the distribution of waiting time of the patients treated, as...

This paper considers the incentives of oligopolistic firms to diversify into technologically related markets when there are diseconomies of scope. There is a rent-extraction incentive for firms to adopt flexible technologies, which enable them to enter technologically related markets, thereby...

New Keynesian literature assumes symmetric industrial structure when analysing explanations of monetary non-neutrality. We analyse the impact of modifying this assumption by allowing for a mixed industrial structure; some industries are characterized by monopolistic competition, and others by...
