In the present paper we have hypothesized an explanation for the fact that the evaluation
of the social impact of law is modeled predominantly by the economic efficiency concept.
Considering the early stages of the concept’s development, we try to make it more
intelligible to the European lawyers.
Electron bunching processes in a carcinotrode (backward_wave oscillator with self_modulation of electron emission) operating in the high_efficiency regime determined previously are investigated. The possibility of obtaining an efficiency of about 80% is explained from the physical viewpoint.
There is by now a large literature arguing that auctions with a variety of after-market interactions may not yield an efficient allocation of the objects for sale, especially when the bidders impose strong negative externalities upon each other. In this note, we argue that these inefficiencies can be avoided by asking bidders prior to the auction to submit any publicly observable payment they would like to make. These payments, so-called flexible entry fees, do not affect the allocation decision of the auctioneer. We show that auctions with flexible entry fees have a fully revealing equilibrium where bidders signal their type before the auction itself takes place.
The main purpose of this monograph is to identify the key factors of risk man- agement efficiency of firm, whose management is able to increase the investment attractiveness of the business in general, as well as the formation of an effective or- ganizational risk management model that allows, on the one hand - to provide reliable protection for companies against unexpected losses, on the other hand - to make a risk management tool for the creation of corporate value. This monograph presents the organization of risk management in accordance with the latest regulatory require- ments. In the monograph authors provide a developed methods for evaluating the effectiveness of existing mechanisms of risk management, based on a representative theoretical review of the scientific literature of leading researchers in the field of risk management and internal control. In addition, an algorithm for evaluating the econom- ic and investment efficiency of the risk management is given, that takes into account the existing methods of performance evaluation, as well as recommendations on the organization of internal compliance as a tool ensuring the consistency of individual and corporate interests of the company. Most of the conclusions and positions pre- sented in the book, confirmed by empirical calculations on the example of Russian and international companies.
The book contains the results of studies to assess the effectiveness of corporate risk management. This monograph is intended for students, teachers and scientists, researchers, and professionals operating in the field of risk management.
Usually marketization is associated with the commercialization as the desire for recovery of the profit. This means replacing the educational functions to the provision of services, with all the unfortunate consequences. However, such an approach is superficial and emotional. The orientation of higher education on the client is very appropriate. Moreover, it is able to put a lot into place.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
