Economic complexity and inclusion of regional economies

Abstract: The paper presents a probabilistic interpretation of the elements of the matrix, which is used to assess the economic complexity in accordance with the traditional approach. Their properties are given, on the basis of which aggregate indicators are introduced that characterize the nesting of the structures of strong sectors of regional economies. It is shown that aggregate nesting indicators are statistically significant explanatory variables for economic complexity. It is proved that the used procedure for calculating the economic complexity is correct in the sense of the existence and uniqueness of the solution. It is shown that the data that are used to assess the economic complexity in accordance with the author’s approach allow to reflect the formation of value chains and groups of related sectors focused on both the external and internal markets. For this economic complexity, calculated on regional data, its high values correspond to large values of the aggregated nesting indicators. Low values of economic complexity correspond to low values of nesting indicators.

Optimal Synthesis in the Reeds and Shepp Problem with Onesided Variation of Velocity

Abstract: We consider a time-optimal problem for the Reeds and Shepp model describing a moving point on a plane, with a onesided variation of the speed and a free final direction of the velocity. Using the Pontryagin Maximum Principle, we obtain all possible types of extremal and, analyzing them and discarding nonoptimal ones, construct the optimal synthesis.

Computer testing of a non-parametric partial equilibrium model prototype

Abstract: On the basis of non-parametric formulations of the production program problem (previously known) and the consumer choice problem (new), a computable partial equilibrium model with a non-parametric representation of both supply and demand is proposed. In this model the problems of the producer and the consumer are represented by simultaneous inequalities of the dual problems pair. This converts the problem of finding an equilibrium to minimizing the differences between objective functions in each pair, summarized over producers and consumers. Such a problem, however, may have multiple local optima. Computer tests on artificial data sets confirmed that inserting such “technical” constraints into a computable model, that are always valid in an equilibrium, can effectively direct the search for a solution using the CONOPT4 procedure to the global optimum (to which the sought equilibrium corresponds). In all 36 tests carried out, equilibrium solutions were found on the first try. The result obtained is of significant importance for the creation of tools used at the sectoral level in managing the unstable economic dynamics that are characteristic of periods of change in systems of dominant technologies. Such tools will make better use of the information in the original empirical data.

ОЦЕНКА ПОТЕНЦИАЛА РОСТА ПРОИЗВОДСТВА И ЭКСПОРТА КОНКУРЕНТОСПОСОБНОЙ ПРОДУКЦИИ АГРОПРОМЫШЛЕННОГО КОМПЛЕКСА (Estimation of the Potential for Growth of Production and Export of Competitive Products of the Agroindustrial Complex)

Abstract: Russian Abstract: Определены стартовые позиции российского агарного экспорта при реализации федерального проекта, состоящие в слабой диверсификации, низком уровне внутриотраслевой торговли, снижении конкурентоспособности по продуктам высоких переделов. Оценен потенциал роста экспорта по товарам, не обладающим сравнительными преимуществами, и по конкурентной сельскохозяйственной продукции – зерну и подсолнечнику. Russian Abstract: The starting positions of Russian agar export in the implementation of the federal project have been determined, consisting in weak diversification, a low level of intra-industry trade, and a decrease in competitiveness for products of high value added. The potential of export growth for goods that do not have comparative advantages and for competitive agricultural products - grain and sunflower is estimated.

Utility Functions, Prices, and Cost Functions on a Lattice of Information Commodities

Abstract: Following Danilov, Koshevoy, and Sotskov (1993, 1994, 1997, 1999a-b), we construct utility (price, cost) functions on a finite set of information commodities like computer programs, books, licenses, etc. Their distinction is that one needs their single instances, since additional copies provide no new information.
