Экстерналии, экономический рост и агломерация
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.
The new economic-mathematical model based on complex variables theory and the new approach to complex variables usage in economics are suggested in the article. The comparison of modeling results of actual production processes using Cobb-Douglass production function and complex variables production function is conducted. It is shown that the instrumental base of economicmathematical methods can be widen with usage of complex variables theory.
In the present paper the game theory is applied to an important open question in economics: providing microfoundations for often-used types of production function. Simple differential games of bargaining are proposed to model a behavior of workers and capital-owners in processes of formation of a set of admissible factor prices or participants’ weights (moral-ethical assessments). These games result, correspondingly, in a factor price curve and a weight curve – structures dual to production function. Ultimately, under constant bargaining powers of the participants, the Cobb-Douglas production function is received.
Dynamic model under consideration, formally speaking, is a concrete realizations of the so-called abstract functional differential equation. On the other hand, it is typical one met with in mathematical modeling economic dynamic processes. The equations of the system contain simultaneously terms depending on continuous time and discrete time typical for econometric models. For this system, control problem is considered and some conditions of the solvability are obtained. Questions of computer-aided techniques for studying these problems are discussed.
We study Krugman's core–periphery (CP) model for most general cases of nonidentical regions and fully characterize instant and long-run equilibria. Assuming immobility of labor, we describe the behavior of equilibrium wages/real wages. Moreover, the relative wages/real wages of industrial workers can both increase and decrease with the population with which they are associated. Under the assumption of industrial labor mobility, possible patterns of economic evolution, as responses to trade freeness, are fully described. We show that in the case of noticeable agricultural asymmetry, all mobile labor inevitably accumulates in countries with larger agricultural populations.

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.
