The notion of Ubiquitous (or Pervasive) Computing was first eloquently described by Mark Weiser at Xerox PARC in the early 1990’s. He proposed a vision in which the personal computing model would evolve from one person using one computer, to many (perhaps hundreds) of computers per person; and that computing would become wirelessly embedded in the world around us, tacitly supporting our work pr...

Unlike perfect competitive markets, in oligopoly electricity markets due to strategic producers and transmission constraints GenCos may increase their own profit through strategic biddings. This paper investigates the problem of developing optimal bidding strategies of GenCos considering participants’ market power and transmission constraints. The problem is modeled as a bi-level optimizati...

This paper uses laboratory methods to evaluate determinants of supra-competitive pricing. The experiment involves three treatments, each with the same market supply, demand, and competitive price. In the baseline treatment, capacity is divided among five sellers so that the competitive price is a Nash equilibrium. Market power is created in a second treatment by reallocating capacity among the ...

Rubinstein and Wolinsky (1990) show that a simple homogeneous market with exogenous matching has a continuum of (non-competitive) perfect equilibria; however, the unique Markov perfect equilibrium of this model is competitive. By contrast, in the more general case of heterogeneous markets, even the Markov property is not enough to guarantee the perfectly competitive outcome. We define a market ...

for any organization sound marketing strategy and quality assurance play vital role in the growth of the organization. the price, quality and service, service centers, friendly attitude, discounts on sales, esthetics, store location and appearance, ease of operations, guarantees and warranties, adopting new ideas, and flexible payments terms were considered to study the perceptions of the respo...

This paper studies a market game under uncertainty in which agents may submit multiple limit and market orders. When agents know their preferences at all states, the competitive equilibrium can be supported as a Nash equilibrium of the market game, that is, agents behave as if they were price takers. Therefore, if the associated competitive economy has a fully revealing rational expectations eq...

In view of the well known core equivalence results in atomless economies, coincidence of market game equilibrium allocations with competitive allocations is tantamount to a three way equivalence between market game mechanisms, competitive equilibria and the core. Based on this idea I propose an equilibrium refinement of market games which allows me to use the core equivalence machinery to provi...

competitiveness is considered as a key criterion for assessing the success of countries, industries and companies. world economic forum defines competitiveness as the set of institutions, policies and factors that determine the level of productivity. moreover, competitiveness can be defined as acquisition more market share, greater profitability and long-term stability and growth of these indic...
