We define a bargaining set for finite economies using Aubin’s veto mechanism and show its coincidence with the set of Walrasian allocations. Then, we rewrite our notion in terms of replicated economies showing that, in contrast with Anderson, Trockel and Zhou’s (1997) non-convergence result,...

We give a notion of bargaining set for finite economies and show its coincidence with the set of Walrasian allocations. Moreover, we also show that justified objections equate with Walrasian objections. Our bargaining-Walras equivalence provides a discrete approach to the characterization of...

We analyze bargaining mechanisms for allocating resources in atomless econo- mies. We provide results proving that it is not necessary to consider the forma- tion of all coalitions in order to obtain the bargaining sets. This is shown under restrictions of different nature, triggering different...

This paper studies economic equilibrium theory with a 'uniformity principle' constraining the magnitudes (prices, quantities, etc.) and the operations (to perceive, evaluate, choose, communicate, etc.) that agents can use.We look at the special case of computability constraints, where all price...

None of the known macroeconomic theories are adequate to understand what to do in a global crisis like the 2020 Global Pandemic. Rational Expectations and monetarism cannot even ex-plain how is that a global crisis like this happens. The IS-LM model was designed to manage business cycles, but...

The thesis of this paper is mathematical formulation of the laws of Economics with application of the principle of Least Action of classical mechanics. This paper is proposed as the rigorous mathematical approach to Economics provided by the fundamental principle of the physical science – the...

Modern exchange theories model a large market, but do not explain single exchanges. This paper considers the phenomenon of single exchange and formulates the general exchange problem in the form of a system of two equations, subjective and objective. Subjective equilibrium is given by the...

This paper defines the single-crossing property for two-agent, two-good exchange economies for classical (i.e., continuous, strictly monotonic, and strictly convex) individual preferences. Within this framework and on a rich single-crossing domain, the paper characterizes the family of...
