Dupuit conjecture for constrained screening: Overall distortion and type-partitioning
In screening with non-concave costs: (i) cycles of active IC constraints can make all packages distorted; (ii) standard screening can be less profitable than price discrimination within a consumer type using first-come-first-served rationing.
The paper is focused on nonlinear pricing, price discrimination and their implementation in actual markets. The introductory section uses simple examples to describe the basic notions and types of price discrimination. Section 2 reviews the main theories behind nonlinear pricing and summarizes the existing results with a focus on consumer choice for those consumers who are keen on quality. It allows the authors in Section 3 to move further to analyze the issues of “prestige” and conspicuous consumption, especially in the case when the sellers exercise their market power over buyers through brands and reputation. Section 4 shows how theoretical results are actually implemented in the automobile market. In particular, the paper shows that cars originating from countries with an established reputation as automobile manufacturers (UK, Germany, Sweden) get the highest mark-up in the market compared to the basic case. Moreover, the analysis of practical methods used in the Russian car market confirms that car dealers manage to sell automobiles as close to consumer reserve prices as possible, employing all types of price discrimination.
For the multiproduct EOQ-models the analysis of several vehicles deliveries feasibility factoring in vehicle capacity is conducted. It is proved that such deliveries with an increase in the number of vehicles that simultaneously used for a single delivery cannot be effective, if a discount is not given for the cost of such a delivery. The necessary and sufficient condition that sets the threshold level of the discount, at which the deliveries by several vehicles are able to compete with the traditional solutions, is established. The cases of numerical calculations are presented in the article.
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.
