We investigate the ability of expected utility theory to account for simultaneous gambling and insurance. Contrary to a previous claim that borrowing and lending in perfect capital markets rules out a demand for gambles, we show that expected utility theory with non-concave utility functions can...

We introduce a novel method of modelling Tullock rent-seeking contests that avoids the complexities encountered by the ‘best response function’ approach. We analyse contests in which there are many risk averse players differing in their attitudes to risk. We establish that, if every player...

This paper discusses the probability of exploiting price variations that may occur during the survey period of any household expenditure survey in order to identify heterogeneous demand responses to discrete price changes. This is possible since expenditure survey contain usually a large number...

We exploit the aggregative structure of the public good model to provide a simple analysis of the voluntary contribution game. In contrast to the best response function approach, ours avoids the proliferation of dimensions as the number of players is increased, and can readily analyse games...

We analyze existence, uniqueness and properties of equilibria in incompletely discriminating Tullock contests with logistic contest success functions, when contestants are risk averse. We prove that a Nash equilibrium for such a contest exists, but give an example of a symmetric contest with...

A game is fully aggregative if payoffs and marginal payoffs depend only on a player’s own strategy and a function of the strategy profile which is common to all players. We characterize the form which this function must take in such a game and show that the game will be strategically...

We study a strategic market game in which traders are endowed with both a good and money and can choose whether to buy or sell the good. We derive conditions under which a non-autarkic equilibrium exists and when the only equilibrium is autarky. Autarky is ‘nice’ (robust to small...

We set out a model of production and appropriation involving many players, who differ with respect to both resource endowments and productivities. We write down the model in a novel way that permits our analysis to avoid the proliferation of dimensions associated with the best response function...
