We study the strategic behavior of voters in a model of proportional representation, in which the policy space is multidimensional. Our main finding is that in large electorate, under some assumptions on voters'preferences, voters essentially vote, in any equilibrium, only for the extreme parties.

This paper shows that generators exercised increasing market power in the England and Wales wholesale electricity market in the second half of the 1990s despite declining market concentration. It examines whether this was consistent with static, non-cooperative oligopoly models, which are widely...

This paper generalises the approach taken by Dasgupta & Maskin (1986) and Simon (1989) and provides necessary and sufficient conditions for the existence of pure and mixed strategy Nash equilibrium in games with continuous strategy spaces and discontinuous payoff functions. The conditions can be...

This paper shows a core-equilibrium convergence in a public goods economy where consumers' preferences display warm glow effects. We demonstrate that if each consumer becomes satiated to other consumers' provision, then as the economy grows large the core shrinks to the set of Edgeworth...

We present a model of altruistically-minded-yet rational-players contributing to a public good. A key feature is the tension between altruism and "crowding-out" effects (players' efforts are strategic substitutes). We find that more altruistic behaviour can raise or reduce welfare, depending on...

This paper develops a theory of policy myopia. Policy myopia arises when rational voters set performance standards that allow elected politicians to distort the portfolio of public investments towards short-term investments. We show that the fact that voters cannot observe immediately how much...

Cheap, abundant and easy to transport and store, coal has been produced and consumed to meet people’s energy needs. The last decade’s growth in global coal use has been driven mainly by developing economies like China, whose phenomenal economic growth has been powered by coal-fired...
