Решение задачи Хотеллинга в безопасных стратегиях
People are intent to make similar choices especially in consumer goods markets. To address both explanations of this persistence, i.e. state dependence and heterogeneity in preferences, we use random coefficient logit model based on scanner panel data on juice purchases. The product differentiation of the chosen category allows us to model three dimensions of state dependence on brand, size and flavor characteristics. We provide evidence that the persistence in brand choices is positively correlated with persistence in size and flavor choices, thus the consumer pattern is prone to be inertial or variety seeking in every product characteristics. Simultaneously we show that the more sensitive to price and promotional activities consumers are, the less inertial is their behavior.
Many industries are made of a few big firms, which are able to manipulate the market outcome, and of a host of small businesses, each of which has a negligible impact on the market. We provide a general equilibrium framework that encapsulates both market structures. Due to the higher toughness of competition, the entry of big firms leads them to sell more through a market expansion effect generated by the shrinking of the monopolistically competitive fringe. Furthermore, social welfare increases with the number of big firms because the pro-competitive effect associated with entry dominates the resulting decrease in product diversity.
The paper analyzes oligopolistic competition in a market for a differentiated product. A comparative analysis of competition models by Cournot (output competition) and Bertrand (price competition) under prerequisites put forward by the authors shows that under Bertrand competition the price level will be lower. Whereas interrelation between firms output and profit is ambiguous (if goods produced are substitutes), and depend, other things being equal, on the attractiveness of the good offered by the firm. The results obtained are illustrated using Russia’s automotive market review. In particular, an attempt is made to classify some decisions made by car producers as the one or the other competition strategy analyzed in the theoretical part of the paper.
Brands and brand management have become a central feature of the modern economy and a staple of business theory and business practice. Contrary to the law's conception of trademarks, brands are used to indicate far more than source and/or quality. This volume begins the process of broadening the legal understanding of brands by explaining what brands are and how they function, how trademark and antitrust/competition law have misunderstood brands, and the implications of continuing to ignore the role brands play in business competition. This is the first book to engage with the topic from an interdisciplinary perspective, hence it will be a must-have for all those interested in the phenomenon of brands and how their function is recognized by the legal system. The book integrates both a competition and an intellectual property law dimension and explores the regulatory environment and case law in both Europe and the United States.
The paper explores how EU competition law has integrated so far the concept of brands in different areas of enforcement. Although EU competition law has engaged in multiple instances with branding and product differentiation, brands do not yet constitute an operational concept in EU competition law. This is due to an important uncertainty as to the normative choices that need to be made with regard to the relation between brands and the formation of consumer preferences. The concerns raised by retailer power and the development of private labels also indicate that the existing economic theory on product differentiation may not also provide a complete picture on the effects of brands on the competitive process and ultimately on consumers. Competition law will also need to tackle the issues raised by the development of ‘social branding’ and the dialogic interaction between brand owners and consumers in the constitution of their brand identity.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
A form for an unbiased estimate of the coefficient of determination of a linear regression model is obtained. It is calculated by using a sample from a multivariate normal distribution. This estimate is proposed as an alternative criterion for a choice of regression factors.
