This paper presents the methodology of collecting and processing open data for the description of both price and non-price characteristics of the apartments in the primary real estate market. The factors that affect the cost per square meter in St. Petersburg and Leningrad region are also analyzed.
The paper studies a problem of optimal insurer’s choice of a risk-sharing policy in a dynamic risk model, so-called Cramer-Lundberg process, over infinite time interval. Additional constraints are imposed on residual risks of insureds: on mean value or with probability one. An optimal control problem of minimizing a functional of the form of variation coefficient is solved. We show that: in the first case the optimum is achieved at stop loss insurance policies, in the second case the optimal insurance is a combination of stop loss and deductible policies. It is proved that the obtained results can be easily applied to problems with other optimization criteria: maximization of long-run utility and minimization of probability of a deviation from mean trajectory.
Nowdays normative legal acts adopting by the government are aimed at improving the efficiency of public expenditures, associated with the stimulation of economic development. A lot of new budgetary tools are entered in our economy. Nevertheles, practical implementation of new mechanisms and tools is enough slow. This situation focuses on the efficiency of public expendirures of all budgetary levels. In accordance with the global experience, the drastic increase of the efficiency and impact of pulic expenditures can be achieved only by the way of creating the modern system of financial management in government, one of the most important part of which is an internal control and audit.
The chapter studies a dynamic risk model defined on infinite time interval, where both insurance and per-claim reinsurance policies are chosen by the insurer in order to minimize a functional of the form of variation coefficient under constraints imposed with probability one on insured's and reinsurer's risks. We show that the optimum is achieved at constant policies, the optimal reinsurance is a partial stop loss reinsurance and the optimal insurance is a combination of stop loss and deductible policies. The results are illustrated by a numerical example involving uniformly distributed claim sizes.

The chapter offers three analytical cases put together as a result of non-formalized face-to-face interviews. it is shown how different manufacturing enterprises - mature chemical firm within the vertically intergated holding, new machine-building plant which serve the demand of resource sector and the relatively new company with the foreign owner - undertake technological innovations. The barriers, motivations and risks which influence the decisions to innovate are descrived. In the end, we show how innovations affect the competitiveness.
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.
