The article synthesizes information on database analysis of state, municipal, and regulated procurement through which Russian contract institutions and the market model are investigated. The inherent uncertainty of quantity indicators on contracting activities and process is identified and explained. The article provides statistical evidence for heterogeneous market structure in state and municipal procurement, and big player’s dominance. A theoretical model for market behavior, noncooperative competition and collusion is proposed, through which the major trends are explained. The intrinsic flaws and failure of the current contracting model are revealed and described. This ineffectiveness is regarded to be not a limitation, but a challenge to be met. If responded to, drivers for economic growth and market equilibrium will be switched on.

The article considers the current and future systems for assessing the effectiveness of the use of state resources to create a national innovation system as a factor in improving the economic security of the state, the author develops a methodological approach to assessing the effectiveness of the use of state resources to create a national innovation system. The cyclical development of the world economy in the conditions of globalization is connected, first of all, with the change of technological structures, as well as with the provision of competitiveness for all levels of economic management. In the domestic and foreign economic literature, there is an idea of the national innovation system, which covers all types of economic objects in the country with innovations, increasing their competitiveness, and, thus, the national economy as a whole, and also directly affects the increase in the level of economic security of the country. Most developed countries and many developing countries have already established or are in the process of establishing their national innovation systems, built either on the basis of models already known and tested in other countries, or new, unique models for building innovation systems. The differences between these models of creation of national innovation systems of different countries are, both in the levels of economic objects, which are the basis of innovative breakthrough, and in the degree of use of public resources: "centralized model", based on public resources, or "market model", or a mixed model of "public-private partnership". These issues are the basis for consideration of the presented article. The methodological basis for writing the article was modern scientific research methods, including: dialectical method, method of system analysis, methods of analogy, comparative analysis, expert methods, structural-functional and normative approaches.

The paper is too long for conveying the message that shadow pricing used as a method of analysis in micro-economic issues of project selection is also useful for analysing macro-economic issues, such as foreign and domestic borrowing by the government, emigration, etc. Much of the methodological discussion in the paper is available in a readily accessible form in several publications of each of the coauthors; In contrast, the specific application of the methodology to Pakistani problems is much too cavalier. While it is hard to disagree with the authors' claim that shadow pricing "constitutes a relatively informal attempt to capture general equilibrium effects" (p. 89, emphasis added), their depiction of traditional analysis is a bit of a caricature: essentially it sets up a strawman to knock down. After all in the traditional partial equilibrium analysis, the caveat is always entered that the results are possibly sensitive to violation of the ceteris paribus assumptions of the analysis, though often the analysts will claim that extreme sensitivity is unlikely. Analogously, the shadow pricing method presumes "stationarity" of shadow prices in the sense that they are “independent of policy changes under review" (p. 90). The essential point to be noted is that the validity of this assertion or of the "not too extreme sensitivity" assertion of partial equilibrium analysts can be tested only with a full scale general equilibrium model! At any rate this reviewer would not pose the issue as one of traditional partial equilibrium macro-analysis versus shadow pricing as an approximate general equilibrium analysis, but would prefer a description of project analysis as an approach in which a macro-general equilibrium model of a manageable size (implicit or explicit) is used to derive a set of key shadow prices which are then used in a detailed micro-analysis of projects.

The conceptual and analytical approach to the definition of an integrative base of sustainable development of territories is proposed, which is based on the idea of construction of economic space and creates real conditions for the establishment and deployment of territorial economic integration. It is proved that the effect of the realization of the economic meta space of the state is influenced by the factor of reorganization of the regional map by cascading format of consolidation of industrial-economic, inter-sectoral and interregional interaction. It is recognized that it is expedient to take into account European economic-statistical principles when creating ten territorial economic and economic districts, the format and scale of which will correspond to the key principles of the liberal-social market model of spatial development.
