In the paper an econometric method of rating scales mapping is suggested. The method is based on the setting up ordered choice models for the ratings and mapping the correspondent latent variables («continuous ratings») with a monotone function. The method takes into account bank's financial indicators and other factors which rating agency's experts use in their work. The method is tested on the real data on Russian banks' ratings and their quarterly balance sheet data for the period 2006:1-2010:4.
This paper presents results of an empirical study which explores Russian banks’ ratings by the econometric modeling method. The nexus was examined between ratings assigned by Moody’s, S&P and Fitch agencies in 2010-2013 years and banks’ financial indicators. Several hypotheses concerning the most promising ways to influence bank rating are tested. According to the research, (1) the most significant factors that reveal the tendency in assigning the rating by each agency during the whole tested period are total assets, liquidity and profitability. Besides, for different agencies’ ratings in some years significant factors are a sufficiency of the capital, activity of crediting of economy, quality of a credit portfolio; (2) The significance of the banks’ capital sufficiency, asset management policy (including liquidity) and profitability varies during the whole period. The impact of these indicators on ratings is higher during the periods following and (especially) previous to financial crises than in time of relative financial stability between crises when they have smaller impact on a rating; (3) financial policy pursued by the bank management can lead to the changes in its rating, at least for some agencies. However the same methods directed on the improvement of financial indicators will lead to the different results for different ratings’ changes. The specific efforts of management will appear more productive for increase of a rating of one agency, others will be less inclined to react to changes of financial performance of banks. The adequacy of obtained results is shown by means of juxtaposing with findings of other domestic and foreign authors.
The paper presents an econometric study of the two bank ratings assigned by Moody's Investors Service. According to Moody's methodology, foreign-currency long-term deposit ratings are assigned on the basis of Bank Financial Strength Ratings (BFSR), taking into account "external bank support factors" (joint-default analysis, JDA). Models for the (unobserved) external support are presented, and we find that models based solely on public information can reasonably well approximate the ratings. It appears that the observed rating degradation can be explained by growth of the banking system as a whole. Moody's has a special approach for banks in developing countries and Russia in particular. The models help reveal the factors that are important for external bank support.
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.
