Administrative and political reorganization is being actively debated even in the mature, stable economies of Western Europe. This paper investigates the possibility that such a reorganization is tied to the integration of economic markets. The paper describes a model where heterogeneous individuals form coalitions for the provision of a public good and shows that the number and composition of these jurisdictions depend on the overall size of the market. The range of economic activities engaged in by jurisdiction members increases when the size of the market increases, and so does the range of their preferences over the public good. The result is a change in the endogenous borders of the jurisdictions, and a reorganization of all coalitions. The optimal number of jurisdictions is unique and increases with market size. In the absence of compensating transfers, however, the decentralized equilibrium need not be optimal and is not unique, although there is no restriction on individuals' ability to coordinate the formation of coalitions. It remains true that a large enough increase in market size will trigger an increase in the number of jurisdictions.

This paper considers why organizations use promotions, rather than just monetary bonuses, to motivate employees even though this may conflict with efficient assignment of employees to jobs. When performance is unverifiable, use of promotion reduces the incentive for managers to be affected by influence activities that would blunt the effectiveness of monetary bonuses. When employees are risk neutral, use of promotion for incentives need not distort assignments. When they are risk averse, it may—sufficient conditions for this are given. The distortion may be either to promote more employees than is efficient (the Peter Principle effect) or fewer. “Promotions serve two roles in an organization. First, they help assign people to the roles where they can best contribute to the organization's performance. Second, promotions serve as incentives and rewards.” (Milgrom and Roberts (1992, p. 364)) “Promotions are used as the primary incentive device in most organizations, including corporations, partnerships, and universities … This … is puzzling to us because promotion-based incentive schemes have many disadvantages and few advantages relative to bonus-based incentive schemes.” (Baker, Jensen and Murphy (1988, p. 600))

This paper examines the optimal structure of hierarchies when workers differ in the range of tasks they can perform. A hierarchical system may reduce costs by allowing most tasks to be handled by unskilled workers. This may however increase delay for those tasks which must pass through several layers before reaching the appropriate level. The paper characterises an optimal hierarchy when such a trade-off exists.

This paper examines how capital tax competition affects jurisdiction formation. We describe a non-cooperative locational model of public goods provision choices, where the levels of taxation and the local public good varieties provided within jurisdictions are selected by majority voting, and where equilibrium jurisdictions consist of consumers with similar tastes. We show that interjurisdictional tax competition results in an enlargement of jurisdictional boundaries, and, even in the absence of intrajurisdictional transfers, can raise welfare for all members of a jurisdiction.

This paper provides an analysis of aggregate behavioural outcomes when individual utility exhibits social interaction effects. We study generalized logistic models of individual choice which incorporate terms reflecting the desire of individuals to conform to the behaviour of others in an environment of noncooperative decisionmaking. Laws of large numbers are generated in such environments. Multiplicity of equilibria in these models, which are equivalent to the existence of multiple self-consistent means for average choice behaviour, will exist when the social interactions exceed a particular threshold. Local stability of these multiple equilibria is also studied. The properties of the noncooperative economy are contrasted with the properties of an economy in which a social planner determines the set of individual choices. Finally, a likelihood function based on the theoretical model is given and conditions for the econometric identifiability of the model are established.

In this paper we model the evolution of income risk and consumption growth. We decompose the time series innovation of the income process into its common and cohort-specific components. From these we compute conditional variances which are used as separate risk terms in a consumption growth equation. Using a long series of British household data we exploit the time-series variation to identify precautionary saving effects and find strong evidence of their importance. Specifically, after allowing for demographic and labour market status, there is an independent role for income risk in explaining consumption growth. Rather than the component that is common across cohorts, however, it is the cohort-specific element that is important in determining changes in consumption growth. This result points to a failure of between-cohort insurance mechanisms.
