This paper provides a comprehensive theoretical model of the political decision making process. Therein two ideologically different political parties compete for power. Their primary instrument in this competition are programmatic concessions in favor of voters and interest groups. As any...

The second welfare theorem and the core-equivalence theorem have been proved to be fundamental tools for obtaining equilibrium existence theorems, especially in an infinite dimensional setting. For well-behaved exchange economies that we call proper economies, this paper gives (minimal)...

We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem stated in terms of prices and commodities into...

We study a class of finite strategic games with the property that every deviation of a coalition of players that is profitable to each of its members strictly decreases the lexicographical order of a certain function defined on the set of strategy profiles. We call this property the...

The problem of allocating indivisible objects to different agents, where each individual is assigned at most one object, has been widely studied. Pápai (2000) shows that the set of strategy-proof, nonbossy, Pareto optimal and reallocation-proof rules are hierarchical exchange rules |...

A key, and often controversial, issue in environmental negotiations is the appropriate extent of harmonization of environmental policies. This paper, within a general equilibrium model of international trade with endogenous pollution discharges, identifies instances in which pollution-tax...

In this paper we review some recent studies of the impact of National Competition Policy on rural Australia. National Competition Policy has tended to assume that both domestic and international deregulation of industry leads to a shift from a noncompetitive to a competitive industry structure....

Most conceptualisations of the bottom billion assume that "the poor" are a minority group in a state of continuous dependency, identifiable by region and demographic. Using a flow analysis (inflow and outflow) of poverty, rather than a stock analysis, we explain why poverty is more appropriately...
