Advanced course on Economics of Networks by Professor Yves Zenou (Stockholm University)
Saint-Petersburg, Russia.It has been recognized for a long time that non-market interactions, i.e. interactions between agents that are not mediated by the market, are crucial to explain different economic phenomena such as stock market crashes, growth, education, religion, crime, etc. In these models, the marginal utility to one person of undertaking an action is a function of the average amount of the action taken by her peers. Peer effects are an intragroup externality, homogeneous across group members, that captures the average influence that members exert on each other. We would like to go further by explicitly providing the particular structure of this dependence on group behavior. In particular, if one considers a network of links between agents, then the peer influence varies across agents in the network, and the intra-group externality we obtain is heterogeneous across agents. This heterogeneity reflects asymmetries in network locations across group members. Networks and peer effects are in the heart of most non-market relationships.

A report on "Evolution of the system of cities under globalization" by Ph.D. student Maxim Goryunov (CERGE-EI, Prague)
Following Anas (2004) we consider a basic model of monopolistic competition to address the question of the efficiency of urbanization: What number of cities is desirable when consumption, production and trade among them are allowed to be determined by market mechanism? We show that original result — decreasing optimal size of the representative city with increase of population (or equivalently, decrease in transport cost) — is robust to the extension of the model on the large class of utility functions. Moreover, sufficiently large population size (sufficiently low transport cost) lead to the efficient city size equal to technologically minimal. This result can be treated as similar to Henderson (1974) since in every city increasing returns in production of only one good are exploited. In addition we show possibility of autarchy as optimal outcome for special class of utility functions.

A report on "Growth of Russian regions: a spatial econometrics approach" by Vera Ivanova (guest of MSSE)
We study the impact of spatial determinants on economic growth in Russia. The research is conducted on the basis of region-level data using methods of spatial econometrics. We find that the key spatial factors of regional economic growth are population, labor density and location of the region. We also show that these effects are cought only after pointing out some outliers which enjoy free access to specific resources non-available for the others.

Referative Seminar
Aggregative games are used to model strategic interaction in many fields of economics, including industrial organization, political economy, international trade, and public finance. In such games, each player’s payoff depends on his/her own actions and an aggregate of all player’s actions. Examples in industrial organization are the Cournot oligopoly model, logit and CES differentiated products Bertrand models (and linear demand models in the short run), and R&D games. We suppose a change affects some of the players, such as cost shocks (subsidies, tariffs), privatization, and a merger or RJV. In a unifying framework, we determine the impact of the change on the aggregate variable, producer surplus and consumer surplus under free entry. We also show that the IIA property of demands implies that consumer surplus depends on the aggregate alone, and the corresponding Bertrand pricing game is aggregative.On May 10-11, 2012 Center Referative Seminar on S. Anderson, N. Erkal and D. Piccinin "Aggregative Games with Entry".

A report on "Two-factor model of international trade: a short-term balance" by Research Fellow Sergey Kichko.
We develop a two-factor trade model with monopolistic competition, a variable elasticity of substitution and trade cost. We show that the country endowed with more capital is a net exporter of manufactured good and its capital price is smaller. The relative GDP share of the capital-endowed country is smaller than its relative share in capital. Last, dumping or reverse dumping may aim depending on consumers' altitude towards variety love and countries relative capital endowment.

A report on "Market Size, Productivity and Enterpreneurship in a Model a’la Melitz" by Research Fellow Dmitry Pokrovsky.
We develop a monopolistic-competition model of closed two-sector one-factor economy, where agents are (continuously) heterogeneous in their entrepreneurship abilities and choose between being employees or entrepreneurs. How the share of entrepreneurs in population changes when the market expands? The sufficient conditions in terms of variable elasticity of substitution are found for expanding or shrinking entrepreneurial sector. The changes in equilibrium consumptions, outputs, prices in the diversified sector are found for several important specifications of utility functions. In particular, special case of CES utility for varieties and Cobb-Douglas preference between the two sectors is the “neutral” borderline case between markets with increasing or decreasing productivity (and share of entrepreneurs) under market expansion.

A report on "Multi-product firms under monopolistic competition: the choice of scope" by Senior Research Fellow of the TMSE Philipp Ushchev.
We propose a model of monopolistic competition with multi-product firms, choosing their product line. Firms bear costs of three kinds: variable production costs, fixed costs of creating a variety (like R&D) and costs of scope, i.e., of the product line length. When the market size (population) increases, the overall variety always increases. The firms’ product line and price increase (decrease) when the elasticity of substitution increases (decreases), whereas the firm size (output) reacts oppositely (when both cost functions are strictly convex). This suggests a theoretical rationale for cross-countries differences in the size and scope of firms, or for possible consequences of trade liberalization.

A report on "Where to build football stadiums? Game-theoretic analysis of the spatial distribution of the problem" by Associate Researcher of the MSSE A. Savvateev, Professor, New Economic School (Moscow)
The task of spatial distribution - is the problem of how to meet the demand for distributed, balancing total transportation costs and the costs of construction items meet the demand. Simply put: there is a city whose residents want to play football. How many build stadiums, where are their places? This problem was studied during the 20th century from the perspective of optimal deployment plan.
However, the new century has given birth to new challenges. What if the people "naughty" and can arbitrarily change the location to meet the demand? And if they can even be collected into groups so that, neglecting the rest of the city, build your own stadium? How to fend off all such threats in the planning of the optimal placement? Overview of the obtained results in this area will be presented in the report.

A report on "Corruption and Cooperation in hierarchical organizations: an experimental study on the Department of the Interior" by professor of the International Institute of Economics and Finance, Guest of the Center A. Belyanin
In recent years the problem of corruption has attracted great interest of academic economists who study it from different points of view. In particular, a significant role in determining its extent and scope of play features of the institutional environment, folding social norms, as well as a reaction to the incentives of agents to corruption and measures to combat it. In this paper, a set of these problems is investigated experimentally by the example of two audiences - students from different the Department of the Interior. The experimental results show that the second audience, unlike the first, is less prone to purely equilibrium behavior, a higher level of cooperativity in protection from anti-corruption audits (including the willingness to "pay" for the safety of other members of the group to the detriment of their personal interests), and relatively more high willingness to abandon corruption, when the benefits of honest work is increasing substantially.

A report on "Models of Economic Geography" by the MSSE Academic Advisor Professor Jacques-Francois Thisse
It is obvious that economic activities are unevenly distributed in space. What are the factors behind this? How and why do consumers choose their place of residence? What affects the location of firms? Why are there urban agglomerations? The report provides an overview of the main approaches and results in the new economic geography, answering these questions.

A report on "Determinants of Interregional Mobility in Russia: Evidence from Panel Data (S. Guriev, Y. Andrienko, 2004)" by student V.Andreeva
Authors investigate political, economic and social factors of migration in Russia using panel data on gross region-to-region migration flows in1992-99. Both the fixed effects and current economic situation matter. People move from poorer and job scarce regions with worse public provision to richer ones in terms of employment opportunities and public goods. However, the lack of liquidity constrains migration. A third of Russian regions are locked in poverty traps.

Presentation was connected with the paper of K.Head, T.Mayer (2010), that provided evidence on the long-term impact of market potential on economic development. Authors evaluated this market potential for all countries in the world with available trade data over the 1960-2003 period and related it to income per capita. Overall results showed that access to markets had essential effect on income per capita within the country, so they reconciled with the previous research in this field (Redding and Venables, 2004; Hering and Poncet, 2010).

A report on "Monopolistic Competition in the presence of large and small firms" by leading researcher of the TMSE Ph.D. S.Kokovin (Institute of Mathematics, Siberian Branch of RAS im.S.L.Soboleva)
In this paper we study a model of differentiated market involving a handful of oligopolistic firms and a myriad of monopolistically competitive firms. Under various specifications of preferences, we show that the presence of small non-strategic firms is sufficient for the strategic interactions among oligopolistic firms to be diluted when monopolistically competitive firms can freely enter and exit the market in response to oligopolistic firms' behavior. Furthermore, the oligopolistic firms adopt the same pricing rule as the monopolistically competitive firms. Our results also hold for heterogeneous firms.

A report on "Oligopoly "A la cournot" in a general equilibrium analysis (Jaskold Gabszewicz, Jean & Vial, Jean-Philippe, Journal of Economic Theory, 1972)", student I.Lashin
In this paper we study a model Gabszewicz and Vial, in which producers compete with production plans, and provide them with resources of the household, get a fixed share of firm output, and then share the benefits of a competitive market. This model focuses on the difference of global competition and local Cournot-Walras equilibrium, shown in the report as an example of economies with different utility functions of households. An equally important issue raised in the article and the report - a significant difference between the results when choosing a different numeraire. Difference in results obtained by the authors when performing simple mathematical operations have not been explained and require further study.

A report on "The multiplicity of equilibria and catastrophe in the general model of monopolistic competition," Ph.D. student of Bocconi University (Italy) A. Gorn.
In this paper we study a generalization of the classical model of monopolistic competition for general utility (non-CES-functions). It is shown that under utility function that generates a non-monotone marginal revenue multiple asymmetric equilibria have to appear at some point. This point is characterized by two global maxima profit function of firms, ie for firms it doesn’t matter which of the two volumes of goods to produce. Therefore, a ratio of (identical) firms chooses to product large quantity of the goods, when other firms produce small quantity good. This idea determines the asymmetry of the equilibrium. The multiplicity of equilibria arises here because it is impossible to strictly define how many firms choose the production of each of the volumes and the ratio of large and small firms can vary greatly. Therefore, asymmetry and multiplicity appear and disappear together.
With increasing population in the country at that point there will be a big gap in the number of firms, consumption of individual variety and utility, which can be interpreted as a catastrophe when utility decreases crucially with decreasing population.
