In this paper, a scheme for using the method of smooth penalty functions for the dependence of solutions of multi-criterial optimization problems on parameters is being considered. In particular, algorithms based on the method of smooth penalty functions are given to solve problems of optimization by the parameters of the level of consistency of the objective functions and to find the corresponding shape of the Pareto’s set.

The main objective is to check whether traditional DCF model, based on stable rational expectations for cash flows and discount rates really works in an intermediate term-from a quarter to three years. The sample was formed from six major companies of oil and gas sector. The main conclusions are-changes of enterprise value are independent of the changes WACC, free cash flow, and operating cash flows. This may be explained by the impossibility to make durable assessment neither for expected cash flow nor for the discount rate, which in fact means failure of strongly rational models like CAPM or MM. To handle out this implied irrationality the new model proposed, based on the stochastic cost of capital, which follows the model of generalized method of moments by J. Cochrane.

This project proposes the use of weather derivatives, a type of financial instrument with a payout based on weather conditions, as a method for Russian farmers to hedge against daily temperature fluctuations. We created a weather derivative simulation tool in Microsoft Excel that calculates the effect of temperature on crop yield and then analyzes how the return of weather derivatives can potentially compensate for crop loss. Based on this tool, we developed a series of recommendations to help implement this system of protection with real users.

The article critically examines the concept of social inequality, and suggests ways to determine it against the background of a wide range of factors that determine inequality among the richest and poorest countries. It also summarizes the inequalities between the three groups of countries by comparing some macroeconomic indicators of socio-economic inequality. We then checked for a linear relationship between the two quantitative variables. Using World Bank data and Reports of the United Nations on human development, we conducted an analysis of individual countries taken from three groups of countries (a total of thirty countries), for the period from 1990 to 2017. After a statistical analysis, we proved that inequality slows down economic growth.

In this paper, the issues of country risk assessment in economic security and sustainability context are investigated. The main object of research is country risk and its structural components. The scientific paper’s main goal is to analyze valuation methods of country risk from different perspectives and suggest a model for country risk measurement that allows adequately evaluate country risk, economic security and economic sustainability level and dynamics, including structural components and their relationships. The paper approaches several main tasks. First, to highlight the importance of country risk evaluation and its assessment in growing global markets, analyzing causes and elements of country risk based on other scientific researches. Second, to explore and clarify advantages and disadvantages of the methods of country’s risk assessment, as well as to investigate sources of country risk and ways how to manage the risk. Third, to apply quantitative and qualitative methods for analysis, formulate, create and present the model of country’s risk assessment in economic security and sustainability context, which will identify factors, influencing country risk and determine their direct and indirect relationship between each other. The last task is to verify practical suitability of the model of country’s risk assessment by performing empirical analysis all over the world, identifying directions for mitigating risk effects.

In this article we focused on the ability to analyze the market and to carry out complex assessment of the company, that is one of the most paramount tasks before financiers. We tried to understand if Nike, Inc. company is overvalued or not. In this work we will consider the analysis of Nike, Inc. by means of Discrete Cash Flow (DCF) as a method and the analysis of financial statements.

The relevance of the topic is explained by the incomplete content of economic models that form the basis for the distribution of state support in the regions, the discrepancy between the expected reactions and real ones, weakness of the results of the implementation of state programs to support the subjects of the agro-industrial complex (hereinafter - agribusiness) as concerns target indicators, and existing mismatch of selected factor indicators and effectiveness ones. In the article, we have proven the absence of a direct correlation between the method of estimating the number of subsidies aimed at supporting the achievement of the target indicators of regional programs and specific economic content of insurance, with the help of factorial (regression) and retrospective analysis. Therefore, the results of this study can serve as a basis for changing the existing model estimates the number of subsidies aimed at supporting the achievement of target indicators of regional programmes-at least in the insurance industry. In the future, it should allow increasing the efficiency of budget financing of activities related to agricultural insurance.
