My early work was related to problems of balance of payments theory. In these works I have used the monetary approach to the balance of payments though I have tended to emphasise the effect of fiscal policy on the balance of payments. Later I have moved to problems of a system of communities.
This research is an extension of the theory of clubs to questions related to provision of public services in an urban context when cities are regarded as groupings of people that collectively provide and consume some public services and at the same time co-operate in the production process. In my work I have emphasised the effect of social mobility on the distribution of production. I have characterised the equilibrium allocation of local public goods, and tax structures and studied the conditions under which costless mobility results in an efficient allocation.
In another line of research I have contributed to the development of the theory of preferential trading by extending the analysis to the case of many goods. This analysis shows that some important results of the two-good custom union theory do not extend to the case where the number of goods exceeds two. This extended model has been used to analyse problems of fiscal harmonisation.
