Product Diversity in a Vertical Distribution Channel under Monopolistic Competition
In Russia, chain stores have achieved considerable market power. In this work, we combine a Dixit–Stiglitz industry model with a monopolistic retailer in order to address the following questions: does the retailer always impair prices, variety of goods, and ultimately welfare? Which market structure is worse: Nash or Stackelberg? What should be the public policy in this area?
Some countries treat public-private partnerships (PPP) within public procurement legislation, whilst others adopt a specially designed PPP law to distinguish PPPs from the routine purchases of goods and services. There is no evidence to suggest which of the approaches is more efficient. Differences are visible even for highly developed economies such as the UK (no special PPP law, rather policy guidance) and the US (special PPP laws adopted in over 30 States, counting.) Does it make sense to have a special PPP legislation? If yes, what should such legislation govern? The last question seems tautological as “a PPP legislation should govern public-private partnerships”, yet we claim that in order to promote economic efficiency, the law should focus on the environment that surrounds public-private relationships. We develop a model of PPP based on the system of standard contractual agreements between the government and the private sector, like the typical contracts used in public procurement. Due to the asymmetric information, some socially desirable projects are too costly to run within a standard procurement contract, this is where partnerships should help. Specific features that are needed to make those costly projects feasible, include a reduction in the information costs through a closer monitoring within the co-production, a reduction in the production costs through a lesser red tape, and extra benefits (distinct from subsidies and monetary rewards) to the private partner, arising from the cooperation with the state (e.g. reputational gains, access to new resources, etc.) In an institutional/cultural environment with [most of] these features in force, a special PPP legislation is not needed (UK and Australia are prominent examples), as there is no scope for a further reduction of the number of infeasible (costly) projects. Otherwise, a PPP law that offers the above features (e.g. by creating a dedicated PPP advisory unit) is socially desirable.
In this paper, we consider the following problem - what affects the amount of investment in knowledge when one of the network firms enters another innovation network. The solution of this problem will allow us to understand exactly how innovative companies will behave when deciding whether to enter the innovation network of another country or region, what conditions affect it and how the level of future investments in knowledge can be predicted.
The paper proposes a list of requirements for a game able to describe individually motivated social interactions: be non-cooperative, able to construct multiple coalitions in an equilibrium and incorporate intra and inter coalition externalities. For this purpose the paper presents a family of non-cooperative games for coalition structure construction with an equilibrium existence theorem for a game in the family. Few examples illustrate the approach. One of the results is that efficiency is not equivalent to cooperation as an allocation in one coalition. Further papers will demonstrate other applications of the approach.
In this paper we consider games with preference relations. The main optimality concept for such games is concept of equilibrium. We introduce a notion of homomorphism for games with preference relations and study a problem concerning connections between equilibrium points of games which are in a homomorphic relation. The main result is finding covariantly and contravariantly complete families of homomorphisms.
This chapter addresses the relationship between class, family and social welfare policies by analysing the construction of the identity category of ‘unfortunate families’ (neblagopoluchnye sem’i) in popular scientific discourses, governmental policy documents and discourses of social services, and by examining how those labelled as ‘unfortunate’ negotiate this identity conferred to them. The chapter shows that gender and class are closely intertwined in the production of this identity, as it is single mothers who are primarily categorised as ‘unfortunate’. In our analysis we draw on multiple sources of data. First, we analyse in-depth and focus group interviews with service providers and clients and participant observation data from a number of Russian cities. Second, we analyse various government documents and social advertisements, mass media materials, social policy and social work textbooks, and popular scientific texts published during the 1990–2010s. This chapter begins with a review of Western theoretical discussions of class in the context of family and welfare in order to see how Russia fits into these debates. Western class analysis was considered irrelevant in the Soviet Union due to the supposedly classless nature of advanced socialism, but the transition to a market economy in the 1990s and the new kind of class society it engendered have made these discussions topical in Russia. In the second section of this chapter we offer a brief description of the main principles of the Soviet and post-Soviet welfare ideologies and the policies towards families. The following sections examine how popular scientific discourses, governmental policy documents and social advertisements, and social service providers construct class with the concept of the unfortunate family. The last section preceding the conclusions analyses how mothers labelled as unfortunate negotiate this stigmatised identity.
The ninth issue of annual Collection of articles consists of four sections: “Analysis of actual economic processes”, “Modeling of financial and market mechanisms”, “Dynamic models”, “Discussions, Notes and Letters”. As a whole nine articles are presented
For n person games with preference relations some types of optimality solutions are introduced. Elementary properties of their solutions are considered. One sufficient condition for nonempty Ca-core is found.
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.
