Competitive equilibrium of incomplete markets for securities with smooth payoffs *
Recently, there has been renewed interest about incomplete security markets. Hart (1975) provided an example of nonexistence of competitive equilibria for incomplete real securities, which are claims to commodity bundles. Given this finding, Duffie and Shafer (1985, 1986a, b) prove generic existence of competitive equilibria of incomplete real security markets. Husseini et al. (1990) Geanakoplo...
متن کاملDynamic Spectrum Management with Competitive Market Equilibrium
In an effort to improve the efficiency of spectrum usage, the cognitive radio (CR) [1] technology was proposed, bringing the possibility of dynamic spectrum management (DSM) [2]. Generally speaking, the multiuser communication systems in the background of CR are interference-limited. Power control is one of the central issues in the design of these systems. This problem can be modeled as a comp...
متن کاملCompetitive Market Structures: a Subset Selection Analysis
Market structure models are used to identify submarkets or to test for the presence of submarkets where within-group competition is much stronger than across group competition. The implicit assumption in such models is that the brands in a submarket compete on the basis of their shared product features. However, if significant variety-seeking effects exist in the market, such an assumption may ...
متن کاملEQUILIBRIUM FOR PROCUREMENT STRATEGY BETWEEN TRIAD COMPETITIVE SUPPLY CHAINS
In today complex worldwide supply chains, intermediary organizations like Contract manufacturers and GPOs are mostly used. Well-known OEMs delegate their purchasing and procuring to these intermediaries. Because of their positive influence on supply chain efficiency, it is very important to investigate the role of intermediaries in today competitive supply chains. One important question arising...
متن کاملYe A Path to the Arrow - Debreu Competitive Market Equilibrium
We present polynomial-time interior-point algorithms for solving the Fisher and Arrow-Debreu competitive market equilibrium problems with linear utilities and n players. Both of them have the arithmetic operation complexity bound of O(n log(1/2)) for computing an 2-equilibrium solution. If the problem data are rational numbers and their bit-length is L, then the bound to generate an exact solut...
