This chapter provides an overview of studies in finance and economics that use automated textual analysis algorithms to analyze the informational content of a wide variety of texts, including journalist’s coverage of news events, management-issued statements, and Internet stock message boards. In these studies, researchers quantify qualitative information with one or more of the following textual tone variables: textual negativity, positivity, and uncertainty. The studies show that textual negativity and positivity conveyed by managers and journalists helps predict future firm level and aggregate economic activity. Textual negativity and positivity, in turn, affect asset prices, although the information is sometimes incorporated with some delay. Textual uncertainty of management-issued information is associated with future cash flow volatility and asset price volatility. In contrast, the textual tone of stock market message board postings is, on average, not very informative in explaining asset prices. The use of automated textual analysis algorithms in finance and economics is a relatively new phenomenon and research in this area is expected to continue to grow.

SummaryAn assay for rapid factor XIII activity measurement has been developed based on the determination of the ammonium released during fibrin stabilization. Factor XIII was activated by thrombin and calcium. Ammonium was measured by an ammonium-sensitive electrode. It was demonstrated that the assay procedure yields accurate and precise results and that factor XIII-catalyzed fibrin stabilization can be measured kinetically. The amount of ammonium released during the first 90 min of fibrin stabilization was found to be 7.8 ± 0.5 moles per mole fibrinogen, which is in agreement with the findings of other authors. In 15 normal subjects and in 15 patients suffering from diseases with suspected factor XIII deficiency there was a satisfactory correlation between the results obtained by the “ammonium-release-method”, Bohn’s method, and the immunological assay (r1 = 0.65; r2= 0.70; p<0.01). In 3 of 5 patients with paraproteinemias the values of factor XIII activity determined by the ammonium-release method were markedly lower than those estimated by the other methods. It could be shown that inhibitor mechanisms were responsible for these discrepancies.

Self-regulation appears to be a special institution where economic actors establish their own rules of economic activity for themselves in a specific business field. At the same time they are the object of control within these rules and the subject of legal management of the controller. Self-regulation contains necessary prerequisites for fundamental resolution of the problem of "controlling the controller". The necessary and sufficient set of five self-regulation organization functions provides efficiency of self-regulation as the institutional arrangement. The voluntary membership in a self-regulation organization is essential for ensuring self-enforcement of institutional arrangement of self-regulation.

Empirical Estimates

Is the Bank of Russia able to control inflation and, at the same time, manage aggregate demand using its interest rate instruments? In other words, are empirical estimates of the effects of monetary policy in Russia consistent with the theoretical concepts and experience of advanced economies? This paper is aimed at addressing these issues. Unlike previous research, we employ “big data” — a large dataset of macroeconomic and financial data — to estimate the effects of monetary policy in Russia. We focus exclusively on the period after the 2008—2009 global financial crisis when the Bank of Russia announced the abandoning of its fixed ruble exchange rate regime and started to gradually transit to an interest rate management. Our estimation results do not confirm standard responses of key economic activity and price variables to tightening of monetary policy. Specifically, our estimates do not reveal a statistically significant restraining effect of the Bank of Russia’s policy of high interest rates on inflation in recent years. At the same time, we find a significant deteriorating effect of the monetary tightening on economic activity indicators: according to our conservative estimates, each of the key rate increases occurred in March and December 2014 had led to a decrease in the industrial production index by about 0.2 percentage points within a year.

Global Problems

The coordination of economic activity at the global level is carried out through different mechanisms, which regulate activities of companies, states, international organizations. In spite of wide diversity of entrenched mechanisms of governance in different areas, they can be classified on the basis of key characteristics, including distribution of property rights, mechanisms of governance (in the narrow sense according to O. Williamson), mechanisms of expansion. This approach can contribute not only to classifying existing institutions but also to designing new ones. The modern aggravation of global problems may require rethinking mechanisms of global governance. The authors offer the universal framework for considering this problem and its possible solutions.

The paper analyzes the impact of the federal regulatory burden on poverty dynamics in Russia. The paper provides regional level indices of the federal regulatory burden on the economy in 2008—2018 which take into account sectoral structure of regions’ output and the level of regulatory rigidity of federal regulations governing certain types of economic activity. Estimates of empirical specifications of poverty theoretical model with the inclusion of macroeconomic and institutional factors shows that limiting the scope of the rulemaking activity of government bodies and weakening of new regulations rigidity contributes to a statistically significant reduction in the level of poverty in Russian regions. Cancellation of 10% of accumulated federal level requirements through the “regulatory guillotine” administrative reform may take out of poverty about 1.1—1.4 million people.

World Economic Crisis

The article analyzes fundamental reasons for the world economic crisis in the light of global technological shifts. It proves that it is caused by the substitution of technological modes. It is shown that sharp increase and slump in stock indices and prices for energy resources are typical of the process of technological substitution which occurs regularly according to the rhythm of long-wave fluctuations of the world economic activity. The article rationalizes a package of anti-crisis measures aimed at stimulating the new technological mode. Its structure and role of the locomotive factor of the new long wave of economic growth are revealed.
