Viscosity in a biological population is the tendency of individuals to have a higher rate of interactions with their closer relatives than with similar numbers of more distantly related individuals. This paper presents a simple method of equilibrium analysis to predict the effect of viscosity in...

The method of fictitious transfers (or lambda-transfers) is used in cooperative game theory to extend solution concepts from the transferable utility case to the more general case of games without transferable utility. The importance of this idea is examined in the context of the history of its...

This paper considers basic constitutional questions about how to elect a legislature. Electoral systems that require blocks of voters to coordinate their votes create a need for pre-election leadership and raise barriers to entry against new parties. Such barriers to entry can rigidity the...

A theoretical model is developed for predicting the relative effectiveness of different electoral systems for reducing government corruption. We consider voting games in which parties with known corruption levels and known positions on a major policy question are competing of legislative seats....

A simple model is used to compare, under different electoral systems, the incentives for candidates to create inequalities among otherwise homogeneous voters, by making campaign promises that favor small groups, rather than appealing equally to all voters. In this game model, each candidate...
