The paper attempts to estimate expropriation risks for shareholders in the Russian economy. On the basis of the survey of nearly 1000 manufacturing firms which was conducted in 2009 a series of special «ownership insecurity indices» is constructed and their variation by types of risks and firms is analyzed. Using various econometric techniques the study examines major determinants of ownership insecurity and evaluates its impact on firms investment and innovative activity. The analysis shows that the Russian economy continues to operate on a shaky basis of attenuated and insecure property rights and that under such condition incentives for economic agents to invest in any long-term projects turn out to be inevitably weak.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
