We study the existence of uniform correlated equilibrium payoffs in stochastic games. The correlation devices that we use are either autonomous (they base their choice of signal on previous signals, but not on previous states or actions) or stationary (their choice is independent of any data and is drawn according to the same probability distribution at every stage). We prove that any n-player stochastic game admits an autonomous correlated equilibrium payoff. When the game is positive and recursive. a stationary correlated equilibrium payoff exists.

The article focuses on the concept of solution-driven marketing. The author says that the Internet and the Web provide an electronic infrastructure that has changed the operational and strategic dynamics of many businesses. As an electronic medium, the Web also facilitates interactive selling approaches such as auctioning and market-making. Solutions-driven marketing arises from a needs-based approach to selling. Such a strategy of identifying needs of a customer and then recommending a product to meet those needs is common in the financial services industry. Solutions-driven marketing offers a value-added link between Web commerce and product customization. At the most comprehensive level of support, Web-assisted needs-based selling should build on information specific to individual customers and their anticipated use of the product. With a decision-assisted interface, customers specify what features they want in a product and the system helps to narrow the available choices and suggest configured solutions

This paper investigates hors, firms' decisions to outsource or internalize production affect their technological performance. While several popular arguments and some anecdotal evidence suggest a direct association between outsourcing and technological performance, the effects of firms' governance decisions are likely to be contingent upon several specific attributes underlying a given exchange. This paper first demonstrates how standard petformance models can improperly suggest a positive relationship between firms' outsourcing decisions and their technological performance. Models that account for firm- and transaction-specific features are then presented, which indicate that neither outsourcing nor internalization per se result in.superior performance; rather, a firm's technological performance is contingent upon the alignment between firms' governance decisions and tire degree of contractual hazards.

In accounting for an odorant's effect on the evaluation of a product, both the odor's intrinsic pleasantness and its appropriateness for that particular product are relevant. When comparing the effects of pleasant smells,consumers are likely to prefer products with appropriate smells to those with an inappropriate smell. We investigated the effect of adding congruent and incongruent odorants on product evaluations for each of three product categories: food (tea, instant whip, cake mix), personal care (shampoo, deodorant, lip balm), and household products (cream cleaner, air freshener, furniture wax). In a between-subjects design, 96 respondents judged scented and unscented products presented in commercial packages of major national brands. The respondents assessed the overall evaluation, 14 to 19 beliefs about the product, buying intention, and the frequency of use for each product. Respondents were instructed to evaluate each product as they would in a store. Although congruency ratings between odor and product show that the manipulation of congruency was successful, no main effect was found for the congruency on overall evaluations of the products. To account for this unexpected finding, we speculate that congruency between odor and product may be more important during product consumption or product use than during its selection. In addition, the odor's effects may have been attenuated in our experiment because we asked our respondents to rate each product on the attribute 'has a nice smell

Employment protection, international specialization, and innovation

We develop a model to analyze the implications of firing costs on incentives for R&D and international specialization. The key idea is that countries with a rigid labor market will tend to produce relatively secure goods, at a late stage of their product life cycle. Consequently, their researchers tend to specialize in 'secondary innovation' which improves existing products, rather than 'primary innovation' which introduces new products. This is roughly consistent with the observed pattern of R&D in Europe versus the U.S. Employment protection does not necessarily harm the country where it prevails, but typically reduces world welfare and the world number of goods
