TL;DR: The authors model competition between two motion pictures in a share attraction framework and conduct an equilibrium analysis of the product introduction timing game in a finite season, finding that the weaker movie may be forced to delay opening.

TL;DR: Using a two-channel model, the authors derive the optimal time to enter the second channel and then obtain a specific parametric solution for movie distributors regarding theater attendance and subsequent sales to video stores.
Abstract: This article focuses on the sale of a product across channels that are entered sequentially. Using a two-channel model, the authors derive the optimal time to enter the second channel and then obtain a specific parametric solution for movie distributors regarding theater attendance and subsequent sales to video stores. Using data from 35 movies, the authors estimate exponential sales curves for both theater attendance and video rentals and demonstrate how knowledge of the sales parameters in the first channel (theaters) helps predict sales in the second channel (video rentals). Finally, from the movie distributor’s perspective, the authors calculate optimal release times based on the model and its estimated parameters. The results suggest that profits would increase if movies were released to video sooner than is the current practice.

TL;DR: Shaked and Sutton as discussed by the authors extended the one-dimensional vertical differentiation model to two dimensions and presented a two-stage game theoretic analysis in which two firms compete first on product positions and then on price, and closed form equilibrium solutions were obtained for each stage in which competitors are unrestricted in their choices of price or product positions.
Abstract: In this paper, the one-dimensional vertical differentiation model Shaked and Sutton [Shaked, A., J. Sutton. 1982. Relaxing price competition through product differentiation. Rev. Econom. Stud.49 3--13.], Moorthy [Moorthy, K. S. 1988. Product and price competition in a Duopoly. Marketing Sci.7Spring 141--168.] is extended to two dimensions and an analysis of product and price competition is presented. A two-stage game theoretic analysis in which two firms compete first on product positions and then on price is conducted. Closed form equilibrium solutions are obtained for each stage in which competitors are unrestricted in their choices of price or product positions. A significant finding of this research is that unlike the one-dimensional vertical differentiation model, firms do not tend towards maximum differentiation, although this solution is possible under certain conditions. When the range of positioning options on each of the dimensions is equal, MaxMin product differentiation occurs. That is, in equilibrium, the two firms tend to choose positions which will represent maximum differentiation on one dimension and minimum differentiation on the other dimension.

TL;DR: In this paper, a review of empirical results from the psychological literature in a way that provides a useful foundation for research on consumer knowledge is provided by two fundamental distinctions: consumer expertise is distinguished from product-related experience and five distinct aspects, or dimensions, of expertise are identified.
Abstract: The purpose of this article is to review basic empirical results from the psychological literature in a way that provides a useful foundation for research on consumer knowledge. A conceptual organization for this diverse literature is provided by two fundamental distinctions. First, consumer expertise is distinguished from product-related experience. Second, five distinct aspects, or dimensions, of expertise are identified: cognitive effort, cognitive structure, analysis, elaboration, and memory. Improvements in the first two dimensions are shown to have general beneficial effects on the latter three. Analysis, elaboration, and memory are shown to have more specific interrelationships. The empirical findings related to each dimension are reviewed and, on the basis of those findings, specific research hypotheses about the effects of expertise on consumer behavior are suggested.

TL;DR: Several theories of relationship marketing propose that customers vary in their relationships with a firm on a continuum from transactional to highly relational bonds as discussed by the authors, but few empirical studies have been conducted.

TL;DR: In this article, a mathematical framework for assessing the value of customer satisfaction is proposed, which enables managers to determine which customer satisfaction elements have the greatest impact, and how much money should be spent to improve particular satisfaction elements.
