Retrading in market games
نویسندگان
چکیده
We study retrading via reopening of trading posts in a market game where the static Nash equilibria yield Pareto suboptimal allocations whenever endowments are Pareto suboptimal. We show that there are allocations on the Pareto frontier that can be approximated arbitrarily closely along some Subgame Perfect Equilibrium path of retrading. The approximation result can also be proved when traders are myopic. However, no allocation on the Pareto frontier can be attained in finite time.

Functional Rational Expectations Equilibria in Market Games
The rational expectations equilibrium has been criticized as an equilibrium concept in market game environments. Such an equilibrium may not exist generically, or it may introduce unrealistic assumptions about an economic agent's knowledge or computational ability. We define a rational expectations equilibrium as a probability measure over uncertain states of nature which exploits all available...
متن کاملInformation-constrained optima with retrading: An externality and its market-based solution
This paper studies the efficiency of competitive equilibria in environments with a moral hazard problem and unobserved states, both with retrading in ex post spot markets. The interaction between private information problems and the possibility of retrade creates an externality, unless preferences have special, restrictive properties. The externality is internalized by allowing agents to contra...

متن کاملAn interval-valued programming approach to matrix games with payoffs of triangular intuitionistic fuzzy numbers
The purpose of this paper is to develop a methodology for solving a new type of matrix games in which payoffs are expressed with triangular intuitionistic fuzzy numbers (TIFNs). In this methodology, the concept of solutions for matrix games with payoffs of TIFNs is introduced. A pair of auxiliary intuitionistic fuzzy programming models for players are established to determine optimal strategies...
متن کاملPricing and Advertising Decisions in a Three-level Supply Chain with Nash, Stackelberg and Cooperative Games
Pricing and advertising are two important marketing strategies in the supply chain management which lead to customer demand’s increase and therefore higher profit for members of supply chains.
