The purpose of this paper is to consider the dynamics of growth in a two state variable and two control variable model where the environment is taken as a constraint. This captures some elements of environmental problems not covered in the cost approach. It also captures the idea that the...

Societies are often compared in terms of the relative shares of the domestic product controlled by government but we don't have much by way of analytical tools to allow us to think about the ways in which changes in these shares affect the characteristics of production and distribution. This...

The purpose of this paper is to contribute to our understanding of the dynamics of struggles over resources by studying a game between a producer that can guard and buy fortifications and a pirate. It is assumed that the returns from defence and raiding depends on the ratio of the resources...

Suppose individuals get utilities from the total amount of wealth they hold and from their wealth relative to those immediately below them. This paper studies the distribution of wealth that maximizes an additive welfare function made up of these utilities. It interprets wealth distribution in a...

Social choice is studied in this paper as a mapping from information on utilities over states of the world to an ordering of those states of the world. The idea of using this type of information originates in the work of Sen and Roberts. This paper differs in that it uses theorems from analysis...

Competition between political parties is a process that unfolds over time whereas formal theories of party competition have tended to take an essentially static, or one-shot, approach. This leaves some gaps in our understanding of the dynamics of campaigning. The aim of this paper is to make up...
