This paper studies geometric properties of semi-algebraic economies with (eventually nonconvex) production - a class which includes linear or Cobb-Douglas preferences, polyhedric production sets and indivisible commodities as well. The main departure with the textbook differentiable viewpoint is...

We investigate properties of correlated equilibria in competitive, pure-exchange market games. We prove that: 1) the game defined in Schmeidler (1980) always admits the no-trade issue as mixed equilibrium outcome; 2) non-pure correlated equilibria may exist in every competitive strategic market...

This paper constructs two feasible strategic market games associated to an economy with infinite-dimensional trade space, finitely many traders, and finitely many firms, such that the set of outcomes induced by pure Nash equilibria coincides with the set of competitive equilibria. In both games,...

We derive from Bernis [2000] a strategic mechanism which fully implements the set of competitive equilibria on a dynamically incomplete reinsurance market VIA Nash equilibria. The mechanism is feasible, and such that the set of coalition proof Nash equilibria coincides with that of Nash...

We present a fairly simple, feasible, price-quantity strategic market game for pure-exchange economies with finitely many agents, such that the set of pure Nash equilibrium outcomes coincides with the set of competitive equilibria. Our set-up encompasses incomplete, non-convex, non-transitive,...

We present the results of a 2D and 3D electrical conductivity simulation of a metal-insulator composite in the range of cluster plasmon frequencies. For the 3D simulations we use an extension of the matrix transfer method that was first introduced to calculate the percolation critical exponents...

The loss angle δ is used to characterize the dielectric properties of inhomogeneous materials, in the framework of percolation theory. We have shown that δ takes the universal value δ = πs/2(s + t) at the percolation threshold (p = pc), and low frequency (ε → 0), where s and t are the...

We report experimental results on the flicker noise in a fractal lattice. The exponent b value is found equal to 1. We give preliminary results on the behaviour of a square lattice made up of resistors whose values are distributed with a R−α probability.

We define a new strategic equilibrium concept -called strong collusion- proof contract -designed to characterize stable communication agreements in games with differential information against non-binding, self enforcing and incentive compatible deviations by coalitions.We then construct a...
