Abstract: The object of the research is the methods that can be used for valuating the cost of business. The subject of the present research is the efficiency of applying modern methods of business valuation compared to traditional methods under the conditions of developing markets. In this research Skavysh analyzes theoretical grounds and algorithms for carrying out the procedure of business valuation based on traditional valuation methods (profitable, cost-intensive, comparative) as well as value added methods, in particular, Economic Value Added (EVA) method. The author has also carried out a comparative analysis of Shareholder Value Added (SVA) indicators and Market Value Added (MVA). In his article Skavysh has used the method of literary sources analysis and has conducted a quantitative comparative analysis of the efficiency of applying modern methods of business valuation based on the example of Russian companies operating in different branches of economy. Based on the results of the research, the author makes a conclusion that under the conditions of developing markets modern valuation methods do not have an essential advantage over traditional methods from the point of view of their efficiency and accuracy. Despite the fact that modern valuation methods have appeared to be a little bit more efficient, the difference between average relative deviations of business value for each sector is quite insignificant thus we cannot speak of some valuation methods being more efficient than others. Based on the results of analyzing data for each sector the author demonstrates that a branch of economy where a company operates has a significant influence on the efficiency of applying modern valuation methods and modern valuation methods need to be improved in order to take into account specific features of companies operating in different sectors of economy.
