Gwyn Bevan and Matthew Skellern review evidence on the effects of hospital competition on quality of care within the English NHS and question whether they support government proposals to extend competition.

The article explores the link between international economic integration and technological capability in colonial India. The example of the iron industry shows that many new ideas and skills flowed into India from Europe, but not all met with commercial success. The essay suggests a reason why....

This paper compares the leader and follower payoff in a duopoly game, as they arise in sequential play, with the Nash payoff in simultaneous play. If the game is symmetric, has a unique symmetric Nash equilibrium, and players' payoffs are monotonic in the opponent's choice along their own best...

If a group is modelled as a single Bayesian agent, what should its beliefs be? I propose an axiomatic model that connects group beliefs to beliefs of the group members. The group members may have different information, different prior beliefs and even different domains (algebras) within which...

This paper argues that Knowledge Management Technology (KMT) is socially constructed in use based on the affordances and constraints of the technology artefact. Since many Knowledge Management (KM) systems are introduced with vague purposes (such as to improve knowledge sharing) it is therefore...

Correlated nonresponse within clusters arises in certain survey settings. It is often represented by a random effects model and assumed to be cluster-specific nonignorable, in the sense that survey and nonresponse outcomes are conditionally independent given cluster-level random effects. Two...

In the framework of judgment aggregation, we assume that some formulas of the agenda are singled out as premisses, and that both Independence (formula-wise aggregation) and Unanimity Preservation hold for them. Whether premiss-based aggregation thus defined is compatible with conclusion-based...

We consider the problem faced by a decision maker who can switch between two random payoff flows. Each of these payoff flows is an additive functional of a general 1D Ito diffusion. There are no bounds on the number or on the frequency of the times at which the decision maker can switch, but...

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and...
