This paper studies the ability of nonmarket institutions to invest optimally in forward intergenerational goods (FIGs), such as education and the environment, when agents are sel sh or exhibit paternalistic altruism. We show that backward intergenerational goods (BIGs), such as social security, play a crucial role in sustaining investment in FIGs: without(More)
Biologists and economists have analyzed populations where each individual interacts with randomly selected individuals. The random matching generates a very complicated stochastic system. Consequently biologists and economists have approximated such a system with a deterministic system. The justitication for such an approximation is that the population is(More)
In this paper, we address the use of adaptive computational modeling techniques in the field of political economy. The introduction considers the advantages of computational methods. The bulk of the paper describes two computational models: a spatial model of electoral competition and a Tiebout model. At the end of the paper, we discuss what the future may(More)
If n points are sampled independently from an absolutely continuous distribution with support a convex subset of 2 , then the center and radius of the ball determined by the bounding median lines (the LP yolk) converge with probability one to the center and radius of the yolk. The linear program of [McKelvey (1986] is therefore an effective heuristic for(More)

In a common agency game, several principals try to in°uence the behavior of an agent. Common agency games typically have multiple equilibria. One class of equilibria, called truthful, has been identi¯ed by Bernheim and Whinston and has found widespread use in the political economy literature. In this paper we identify another class of equilibria, which we(More)

1 We examine legislative policy making in institutions with two empirically relevant features: agenda setting occurs in real time and the default policy evolves. We demonstrate that these institutions select Condorcet winners when they exist, provided a sufficient number of individuals have opportunities to make proposals. In policy spaces with either pork(More)
