TL;DR: In this article, Arrow's theorem is shown to be valid for measurable spaces of economic agents even with only a Boolean algebra of measurable coalitions, and it is shown that purely competitive social welfare functions which ignore negligible coalitions can be handled by passing to a Boolean quotient algebra with the ideal of negligible coalition.

TL;DR: In this article, the generic properties of a simple non-collegial preference function σ, whose domain is the class of ordinal utility profiles on a smooth manifold W of policy alternatives, were determined.

TL;DR: In this article, it was shown that if the number of agents n is a prime integer strictly greater than p, then there exists at least one efficient, anonymous and neutral social choice function, in short eanscf, that can be implemented by a dominance-solvable voting scheme.

TL;DR: In this article, the notion of determining coalitions was generalized to committee games, and a complete characterization of the set of deciding coalitions of a committee was given, in the light of real-life data on formation of coalitions in town councils in Israel.

TL;DR: In this paper, a model of capital accumulation is considered and the relation between the optimal path and the initial capital stock is analyzed, and the existence of optimal paths of capital-accumulation is proved.

TL;DR: In this article, a general model of a decentralized economy evolving over an infinite time horizon is presented, where alternative notions of price systems, competitive equilibria, efficiency and optimality are introduced.

TL;DR: In this paper, the existence of invariant measures for Markov processes of temporary equilibria is derived under assumptions on demand and supply functions that allow the use of Doeblin's condition.

TL;DR: In this article, it was shown that for a large subset of utility functions in the space of all C1 utility functions and for all prices the mean demand of those consumers whose taste is represented by a given utility function in that subset is uniquely determined.

TL;DR: In this article, the authors modify the usual axiomatisations to deal with the case where α is restricted to rational values, or even further to values of the form m /2 n corresponding to mixtures built up from even bets.

TL;DR: In this paper, the sufficient second-order conditions for local Pareto optimum were proved for the case of the case where the second order condition is independent of the first-order condition.

TL;DR: In this article, the problem of smoothing demand by aggregation in a two-step procedure, corresponding to the two different constituents of consumption characteristics, wealth and preferences, is considered and it is shown that, for any preference, aggregation with respect to wealth yields a mean demand which is almost everywhere C 1.

TL;DR: Using Mather's multijet transversality theorem, this article obtained generic results for uniqueness of mean maximizers and continuity of aggregate demand in the context of mean-maximizers.

TL;DR: In this article, an elementary proof of a generalized version of Aumann's Measurable Utility Theorem is given, and the proof is shown to be equivalent to the one presented in this paper.

TL;DR: In this article, the authors extend the results of Debreu's "Economies with a Finite Set of Equilibria" to the case where demand functions are assumed only to be continuous and to satisfy a certain technical condition.

TL;DR: In this paper, it is shown that it is almost equivalent to know with accuracy the equilibria of every economy or simply to know just the number of equilibrium conditions of these economies.

TL;DR: In this paper, the authors study a class of disequilibrium processes defined by differential inequalities, where prices are adjusted according to the agent's short-term demands, in both pure exchange and monetary settings.

TL;DR: In this article, the authors generalize the concept of efficiency in multi-criteria problems from being the property of a point to that of a set of points, allowing a variety of solution concepts to these problems.

TL;DR: In this paper, a temporary equilibrium model of a production economy with various capital markets in which producers maximize the expected utility of cash flows in various periods is considered, and it is shown that if contracts to buy or sell goods at future periods can be trated in a market and if the producer's utility functions are increasing in the first period, then the temporary equilibrium allocations are technically efficient.
