Двойная национально-политическая идентичность
Migration is a powerful driver and important consequence of economic, political and social change. Because of its great impact on societies, migration needs to be adequately measured and understood. Reliable statistical data is the key to the basic understanding of this important phenomenon. Yet, in many countries, even the most general statistics on migration are incomplete, out-of-date or do not exist. Improvement in this area requires knowledge of the principles of collecting, compiling and analyzing migration statistics. Likewise, policymakers and other users need to be aware of the definitions and measurement issues related to the data to be able to interpret them. The present guide was prepared under the responsibility of the United Nations Economic Commission for Europe in the framework of the project “Strengthening national capacities to deal with international migration: maximizing development benefits and minimizing negative impacts”. The project involved all five regional commissions of the United Nations and was financed from the United Nations Development Account. The guide is intended for practitioners and professionals whose work is related to migration and migration statistics. It focuses on the specific context of migration processes in Eastern Europe and Central Asia. We expect that the practical examples and international recommendations presented herein stimulate interest and improve understanding and facilitate production, dissemination and use of statistics on international migration.
The object of study of this paper is a regional economic system which is complex, dynamic and developable by nature. The reproduction of material wealth necessary for the region is provided in the process of functioning of the above system through the interaction between the combinations of subjective (personal) and objective (material) elements, thereby meeting regional environmental and economic needs.
In this paper we study convergence among Russian regions. We find that while there was no convergence in 1990s, the situation changed dramatically in 2000s. While interregional GDP per capita gaps still persist, the differentials in incomes and wages decreased substantially. We show that fiscal redistribution did not play a major role in convergence. We therefore try to understand the phenomenon of recent convergence using panel data on the interregional reallocation of capital and labor. We find that capital market in Russian regions is integrated in a sense that local investment does not depend on local savings. We also show that economic growth and financial development has substantially decreased the barriers to labor mobility. We find that in 1990s many poor Russian regions were in a poverty trap: potential workers wanted to leave those regions but could not afford to finance the move. In 2000s (especially in late 2000s), these barriers were no longer binding. Overall economic development allowed even poorest Russian regions to grow out of the poverty traps. This resulted in convergence in Russian labor market; the interregional gaps in incomes, wages and unemployment rates are now below those in Europe. The results imply that economic growth and development of financial and real estate markets eventually result in interregional convergence.
An initial–boundary value problem for the generalized Schrödinger equation in a semi-infinite strip is solved.
A new family of two level finite-difference schemes with averaging over spatial variables on a finite mesh is constructed, which covers a set of finite-difference schemes built using various methods. For the family, an abstract approximate transparent boundary condition (TBC) is formulated and the solutions are proved to be absolutely stable in two norms with respect to both initial data and free terms. A discrete TBC is derived, and the stability of the family of schemes with this TBC is proved. The implementation of schemes with the discrete TBC is discussed.
The report provides a review of sources and quality of statistics on international migration in selected countries of the Commonwealth of Independent States (CIS): Azerbaijan, Kazakhstan, Kyrgyzstan, the Russian Federation and Tajikistan. The report was prepared under the responsibility of the United Nations Economic Commission for Europe in the framework the project “Strengthening national capacities to deal with international migration: maximizing development benefits and minimizing negative impacts”.
