The paper contributes to the methodology of linear programming applications to the optimal risk management. It is suggested to model two-stage decision making processes (before and after instantiation of stochastic, e.g. weather, parameters) using empirical distributions of stochastic parameters. This ensures that the resulting production programme does not suffer from resource shortages under any instantiation of the stochastic parameters within the linear combination of actually observed instantiations.

The marginal product of arable land and grassland is estimated by a shadow price parameterization. The shadow prices are obtained from multiple runs of a linear programming model of the Moscow region land market that randomly uses varying crop yields. The marginal product of land approximates the possible rental price of agricultural land from 2001-2003 under the assumption of a properly functioning land market. In 2003, this value (for arable land) varied from 290 to 1,309 roubles, depending on distance from Moscow and soil fertility. Higher crop yields negatively influence the marginal land product values. There is a declining trend of these values during the studied period, which impedes emerging market institutions.

The results from dynamic DEA modeling of Moscow region corporate farms during 1995-2004. The following is concluded. The major source of inefficiency is a suboptimal input-output mix. One of the reasons for that is transitional markets volatility. Technical inefficiency is minor and mostly due to congestion problems. During the specified period the limiting factor of efficiency changed from the lack of liquidity to the lack of working power. There is an evidence of higher innovational capacities of larger corporate farms. Resources scarcity was found to improve the efficiency. Soft and too hard budget constraints simultaneously hamper the studied farms efficiency.

The corporate farm size determinants are studied by the instrumentality of the dynamic DEA model from (166), which was re-estimated after fixing the identified data errors. The results suggest positive dependence of efficiency on size, which is not only due to the wider growth opportunities of highly efficient farms; return to scale is found to be volatile, thus hardly affecting managers' decisions concerning farm size; the best-practice farms (in terms of dynamic efficiency) keep growing, while others shrink their size.

Determinants of the Moscow region corporate farms dynamic efficiency are studied by the instrumentality of the dynamic DEA model from (166), which was re-estimated after fixing the identified data errors. The studied period is 1996-2004. The major limitation of dynamic efficiency was proved to be sources of production costs financing in 1996 and lack of labour later on, in contrast to a body of studies which argue labour-abundance of Russian corporate farms. The expected effect of increased labour supply is the greatest in the least efficient corporate farms (in terms of dynamic efficiency).

A set of dynamic DEA models is applied to investigate the determinants of farm size of Moscow oblast corporate farms in the period 1996-2004. New institutional economics is found to be more relevant to explaining farm sizes and their changes than the neo-classical framework. The results prove the hypothesis that the development of farm size is mainly caused by reducing transaction costs associated with getting access to product markets.

A system dynamics model is developed that allows for retirement of assets after bankruptcies. The aim of the model is to select hypotheses about influence of assets' retirement on economic growth and inflation under restrictive monetary policies. The core of the model consists of relations between mean profitability (variance is fixed) and increment of money in turnover; between credit issue and economic growth; between profitability and bankruptcy.

212. A Microeconomic Model for Subsidies Allocation: the Case of Belarus CD publ.

Conference proceedings: Institutions in Transition – Challenges for New Modes of Governance: 16-18 June 2010. Halle (Saale), Germany

18 Iryna Kazakevich
The paper develops a microeconomic methodological framework that allows approaching subsidy allocation across the types of assets and impact of subsidies on agricultural outputs and profits. The methodology is based on a non-parametric production frontier estimation. The empirical application is made to 1084 Belarusian corporate farms. The results suggest targeting governmental support at grain and milk production. In this case, 4.14 trillion Belarusian roubles of subsidies increase the overall profit of the sample farms by 1.46 trillion. In the case of targeting, the farms with higher overall efficiency are more sensitive to the support and are able to absorb larger amount of subsidies. The opposite is true in the absence of targeting.

The estimates of internal transaction costs (ITC) using data of 1998 and 20052007 from Moscow oblast corporate farms are presented. Compared to (198), several minor bugs are found and fixed in calculations. Both theoretical and empirical models are revised so to make them simpler and implying conditions for stronger estimates. Absence of significantly positive institutional changes is supported, whereas in short run (2005-2009) there is an evidence of negative changes. It is confirmed that larger farms face larger ITC. The influence of ITC on allocative efficiency is found negative, except 1998 when the results are indefinite. Higher technical efficiency implies higher ITC.

The system dynamics model of growing economy consisting of several populations characterized by the population-specific dependence of transaction costs and social inequality on economic activity scale indicators is studied. It is found that such model reproduces basic characteristics of competition between different institutional settings, like co-existence of different settings (particularly, infinitely long existence of settings which are strictly worse than their competitors), faster growth of the worst setting in the short-term period, break-even (catastrophical) population changes of settings.

Non-parametric production frontier models of Russian corporate farms, family farms and household plots are developed using regional (oblast) level data. Price growth is found to stimulate production on household plots to a larger extent than on corporate farms. Soaring grain prices are able to cause decreasing production of other agricultural outputs. Additional input of mineral fertilizers, compared to fixed assets, stimulates larger capital value growth on corporate farms (per rouble of input). Family farms are the best place to capitalize agricultural land, while corporate farms demonstrate advantages in capitalizing cattle.

The possibility of computer simulations application is argued to satisfying the information demand of investment portfolio risk analysis in the cases when real projects shares are included in the portfolio. The necessary data set, characterizing the projects risk, is made available by the simulation cash flow model, which generates variational series of each project's NPV and IRR.  The empirical base of the model consists of the project feasibility study materials, data on project-specific prices variation and aggregated price indices. The instrumental methods, based on the proposed model, allow making decisions about capital investment as well as about forms and amount of state support aimed at improving investment attractiveness of the agro-industrial complex.

N.A. Kubyshina
The monograph studies the case of scientific substantiation of such a middle-term plan of investment, financial and operational activities of a corporate farm that ensures low sensitivity to risks and uncertainties. For this purpose, a new approach to agricultural producers' operations research is introduced that is applicable in the situation of scarce input data. This approach is based on a multi-stage linear programming model, which makes use of the empirical distribution of probabilities of uncertain parameters (so called ED-model). The solution of the ED-model is an optimal program which remains feasible under any random conditions taken from the set of the conditions that have been actually observed in a given set of years in the past. The model runs under a limited number of scenarios, which are represented by the parameters for which the empirical distribution is not accessible. The overall approach ensures better control over risk and uncertainty factors in comparison to other approaches that could be implemented subject to the available input data.

The possibility of computer simulations application is argued to satisfying the information demand of investment portfolio risk analysis in the cases when the shares of interrelated real investment projects are included in the portfolio. A complex of cash flow simulation model and portfolio simulation model is developed that makes it possible to approach statistic characteristics of economic effect of investment projects and estimate expectation value of investments in real projects in the presence of governmental support. The empirical base of the model consists of the project feasibility study materials, data on project-specific prices variation and aggregated price indices. The instrumental methods, based on the proposed model, allow making decisions about capital investment as well as about forms and amount of state support aimed at improving investment attractiveness of the agro-industrial complex.

291. Estimating managerial transaction costs on dairy farms in the Moscow region publ. Izvestia of Timiryazev Agricultural Academy, 2014, №3, p.120-138. 41  
The author's methodology of econometric estimation of managerial transaction costs (MTC) per unit of output is applied to testing the following hypotheses: about non-decreasing МТС during the periods 1998 to 2007 and 2005 to 2007; about their positive correlation with farm size and with technical efficiency; about their negative correlation with allocative inefficiency. None of these hypotheses are rejected. The evidence of regressive evolution of internal farm institutions during the period 2005-2007 is found. MTC downgrade the competitiveness of the studied farms. However, large potential of decreasing MTC can be found in relatively small number of farms, thus implying limited economic motivation to restructuring aimed at cutting MTC down.

315. Econometric Analysis of Expansion of Surface Transportation Networks  publ. Economics and mathematical methods, 2016, vol.52, issue 2. – P.60-74. 31  
A disequilibrium theoretical model of long-term economic dynamics, which considers availability of an aggregated resource and satisfaction of needs in specific outputs, is tested against the expansion of surface transportation networks. The 1871–2013 time series of the length of the USA railroads, highways, pawed roads, surfaced roads and total automobile roads, some of which lack numerous observations, are used for the empirical testing. Two incomplete non-linear auto-regression empirical specifications are applied, which differ in the lag duration (one year and 13 years). The both are estimated using generalized maximum entropy (GME) procedure, which is enriched with the endogenous supporting values for the parameter estimates. For the purpose of testing null hypotheses a non-parametric criterion of statistical indiscriminability of two series (reference and compared) is developed, using an area of intersect of polygons of empirical distributions as a critical value. The empirical specification assuming one year lag supports the proposed theoretical model. The parameter estimates do not support the influence of Schumpeterian technological structure changes on the extension of the transportation networks. The possible reason is the fixed correspondence between a given type of the network and a certain technical structure, which is assumed by the empirical specification. The specification with the 13 year lag is rejected, thus giving no evidence for the significance of the investment lag for the transportation network expansion processes.

320. Economic and Mathematical Modeling of EAEC Agri-food Policy  pre-print РАНХиГС. М., 2016. 126 E. Shishkina
The paper presents the economic and mathematical analysis of the likely consequences of the transition to a single agri-food policy in the three countries EAEC - Belarus, Kazakhstan and Russia. Use any copyrighted modification of economic-mathematical model of partial equilibrium EPACIS, which eliminates the drawbacks associated with alternative solutions and computational problems. The expediency of a conservative approach to integration processes in the EAEC, consisting in the integration of primary markets, the integration of the least prone to stress; the priority of improving the competitiveness of inefficient sectors to the integration of markets; ready to suspend the acts aimed at deepening integration, the detection of adverse effects.

321. The methodology for modelling agricultural and food policy in the framework of euro-Azian integration publ. Izvestia of Timiryazev Agricultural Academy, 2016, №3, p.106-126.  36  
A mathematical model for modeling agricultural and food policy in the core countries of Eurasian Economic Union (EAEU), namely Belarus, Kazakhstan and Russia, is developed on the basis of earlier EPACIS project, which originates in Leibniz Institute of Agricultural Development in Transition Economies (IAMO). Workarounds are provided for some imperfections of the original model that expose themselves during simulations that allow for bilateral international trade, namely presence of multiple equilibrium solutions, large systematic bias and occasional computational problems. The model outcome is analyzed for the scenario of equal average subsidies per unit of each output in the three countries (separate for direct subsidies, input subsidies and the support of agriculture besides subsidizing producers). The scenario assumes securing the gross amount of subsidies of each type across the three countries, allowing their burden to be redistributed from one country to another. The major scenario effects are the growth of foreign trade turnover in all three countries (e.g. Russia's import from two other countries grows by 3,3% and from the rest of the world by 4,5%, while its export grows by 6,8 and 13,2% correspondingly) and growth of state support of agriculture in Kazakhstan by 62,6%. Hence, international traders will promote this scenario, while the government of Kazakhstan will tend to hamper it. Other actors, including consumers and producers in all the three countries and governments of Belarus and Russia receive marginal effects. On this reason, they will stay neutral thereupon the scenario is about to be implemented.

326. An econometric model of motoroad and railroad lengths in the USA publ. System modeling of social and economic processes: Summaries of the 38th international scientific seminar / V.G. Grebennikov, I.N. Shchepina, eds. Voronezh, Voronezh State University, 2016. - P.402-405. 6  
For the purpose of verification of a disequilibrium theoretical model of traffic networks expansion considering availability of an aggregated resource and consumption of traffic services, an incomplete (in terms of factors taken into account) non-linear autoregressive econometric model of motor and rail road lengths is developed for the period 1871-2013 (the data on motor roads are available from 1904 on). Parameters of the model are estimated by means of the general maximum entropy (GME) estimator. The results fit into the theoretical model. An investment lag and a technological structure are both found insignificant.
