We calibrate a sequence of four nested models to study the dynamics of wealth accumulation. Individuals maximize a utility function whose arguments are consumption and investment. They desire to accumulate wealth for its own sake — this is not a life-cycle model. A competitive firm produces a...

A brief, historical review of the study of the interdependency between politics and economic distribution is offered. While the impact of economic interests on politics has been acknowledged for thousands of years, and the impact of politics on distribution for hundreds, it is only in the last...

We survey critically the brief history of modeling party competition in general elections, beginning with the Hotelling-Downs model with a unidimensional policy space, and the Wittman model with endogenous parties, to the multi-dimensional citizen-candidate and PUNE models. Some applications of...

In a citizen candidate equilibrium, there are n candidates each of whom announces a policy in a policy space of dimension d. Thus the policy equilibrium lives in a space of dimension nd. We show, in a canonical example, that the equilibrium manifold is generically of dimension nd. In particular,...

The justification of using GNP per capita as a measure of economic development is utilitarian ethics plus an assumption that no needs are more urgent than others. Here, we advocate a measure of economic development based on the degree to which the society in question has equalized opportunities...

Anthropogenic greenhouse gas (GHG) emissions have caused atmospheric concentrations with no precedents in the last half a million years, inducing serious uncertainties about future climates and their effects on human welfare. Recent climate science supports the view that the climate...

J. Rawls and R. Dworkin have each used veils of ignorance to justify equality (Rawls) or to compute what equality entails (Dworkin). J. Harsanyi has also derived a distributive ethic from a veil of ignorance argument, which, although not egalitarian, is believed by Harsanyi to be not excessively...

We propose a theory of party competition (two parties, single-issue) where citizens acquire party membership by contributing money to a party, and where a member?s influence on the policy taken by her party is proportional to her campaign contribution. The polity consists of informed and...
