Internal migration of scientists in Russia and the USA: the case of applied physics
This book focuses on the questions of how territorial differences in productivity levels and unemployment rates arise in the first place and why territorial differences in labor market performance persist over time. Unemployment divergence and unemployment club convergence have been touched on in a large number of works and have recently also been studied using spatial econometric analysis. In this book we aim to develop the debate to include several important new topics, such as: the reasons why structural changes in some sectors cause slumps in some regions but not in others; the extent to which agglomeration factors explain regional imbalances; the degree of convergence / divergence across EU countries and regions; the role of labor mobility in reducing / increasing regional labor market imbalances; the impact of EU and country-level regional policy in stimulating convergence; and the (unsatisfactory) role of active labor market policy in stimulating labor supply in the weakest economic areas.
We consider the dependence of the growth arte on the elasticity of substitution within the framework of a model with the agents' mutual dependence. This model is interpreted as a network structure. the development is explined as the agents' valus increase in a dynamic system described by functions which display constant elasticity of substitution (CES). We investigate the cases of high and low complementarity of activities. In particular, we receive conditions allowing to identify the cases when the elasticity of substitution has the positive (negative) effect on growth rate under high (low) complementarity of activities. Additionally we analyse the influence of the individual agent's productivities on the growth rate. Finally we give a potential generalisation of the model allowing for different growth rates of the agents.
We consider a game equilibrium in a network in each node of which an economy is described by the simple two-period model of endogenous growth with production and knowledge externalities. Each node of the network obtains an externality produced by the sum of knowledge in neighbor nodes. Uniqueness of the inner equilibrium is proved. Three ways of behavior of each agent are distinguished: active, passive, hyperactive. Behavior of agents in dependence on received externalities is studied. It is shown that the equilibrium depends on the network structure. We study the role of passive agents; in particular, possibilities of connection of components of active agents through components of passive agents. A notion of type of node is introduced and classification of networks based on this notion is provided. It is shown that the inner equilibrium depends not on the size of network but on its structure in terms of the types of nodes, and in similar networks of different size agents of the same type behave in similar way.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
This paper studies a model of game interaction with externalities on a network, in which agents choose their level of investment. We compare two concepts of equilibrium: standard Nash definition and “Jacobian” definition of equilibrium with externalities. It is shown that in both cases agents may be passive, active and hyperactive, and conditions for optimality of these types of behavior are derived. In particular, we study the case of a full homogeneous network and show that an increase in its size facilitates active state of agents but reduces their utility.
This is a book about the “how to” of one of the most important aspects of diaspora engagement — leveraging countries’ talent abroad to support development at home. The understanding that the diaspora (emigrants and their descendants who retain ties to their countries of origin or ancestry) can be a critical partner for development has emerged fairly recently, due in large part to the experience of two new global powers — China and India — whose rise to prominence owes much to the contributions of their talent abroad. In the amazingly short span of about 15 years, the importance of the diaspora to development has evolved from a novel and somewhat heretical hypothesis to conventional wisdom. Now it is commonly acknowledged that diasporas can be important, but the path of developing policies and programs to help realize the promise of diasporas has been fraught with frustration and disappointment. Diaspora contributions seem to come spontaneously rather than as a result of policy interventions; they are a matter of serendipity. By focusing on policy interventions that effectively promote diaspora contributions, the book fills an important gap in the literature.
We consider a dependence of the growth rate on the elasticity of factor substitution in a framework of a model of mutual dependence of n agents. This model is interpreted as a network structure and can be used to analyze agglomerations. The development is modeled as an increase in values of the agents in a dynamic system with CES functions. We investigate the cases of high and low complementarity of activities. In particular, we receive conditions allowing the identification of the cases when the elasticity of factor substitution has a positive effect on the growth rate under high complementarity of activities, and when the elasticity of factor substitution has a negative effect on the growth rate under low complementarity of activities.
The transition to market economic systems in the countries of Central and Eastern Europe and the former Soviet Union involves fundamental shifts in the sectoral allocation of resources, in particular, dramatic changes in employment structures. Development of services in Russia turns to be more impressive than in many other transitional countries. This paper uses the Baumol-Fuchs model of the service sector expansion to estimate underdevelopment of services in Russia prior the transition and measure the progress in catching-up that has taken place thus far. Based on the Russian Longitudinal Monitoring Survey (1994-2000) empirical analysis demonstrates that sectoral variation in the difference between withdrawal from and entrance to the labor force is the main reason of changing distribution of labor. For job-to-job transitions low quality of current job matches, tenure effects and labor market segmentation are the most important explanation of inter-sectoral labor mobility.
Using two rounds of nationally representative household survey data in this study, we measure the impact on poverty in Nepal of local and international migration for work. We apply an instrumental variables approach to deal with nonrandom selection of migrants and simulate various scenarios for the different levels of migration comparing observed and counterfactual household expenditure distribution. Our results indicate that one-fifth of the poverty reduction in Nepal occurring between 1995 and 2004 can be attributed to higher levels of work-related migration and remittances sent home. We also show that while the increase in international work-related migration was the leading cause of this poverty reduction, domestic migration also played an important role. Our findings demonstrate that strategies for economic growth and poverty reduction in Nepal should consider aspects of the dynamics of domestic and international migration.
Several approaches to the concept of fatherhood present in Western sociological tradition are analyzed and compared: biological determinism, social constructivism and biosocial theory. The problematics of fatherhood and men’s parental practices is marginalized in modern Russian social research devoted to family and this fact makes the traditional inequality in family relations, when the father’s role is considered secondary compared to that of mother, even stronger. However, in Western critical men’s studies several stages can be outlined: the development of “sex roles” paradigm (biological determinism), the emergence of the hegemonic masculinity concept, inter-disciplinary stage (biosocial theory). According to the approach of biological determinism, the role of a father is that of the patriarch, he continues the family line and serves as a model for his ascendants. Social constructivism looks into man’s functions in the family from the point of view of masculine pressure and establishing hegemony over a woman and children. Biosocial theory aims to unite the biological determinacy of fatherhood with social, cultural and personal context. It is shown that these approaches are directly connected with the level of the society development, marriage and family perceptions, the level of egality of gender order.
This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
