The objective of this paper is to examine the internal and external factors of product and organizational innovations, and specifically to discuss the role of the business environment and administrative corruption as barriers of intra-firm innovations in transitional economies. The analysis was based on data from Business Environment and Enterprise Performance Survey of the EBRD and the World Bank conducted in 2009. Consistent correlations between product innovations and both high administrative obstacles and the growth of corruption costs were revealed. On the contrary, organizational innovations were largely not correlated with the respondents’ assessments of business climate.
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.
