Article
Russia has emerged as a major wheat exporter since the beginning of the 2000s, and today, it possesses high market shares in several wheat-importing countries in the Middle East and North African region. This has raised concerns that Russia might abuse its dominant market position by pricing above marginal cost. Using a novel dataset with weekly in...

Der vorliegende Beitrag stellt empirische Ergebnisse zur Analyse von Marktverhalten der russischen Exporteure auf den internationalen Märkten für Düngemittel vor. Der Fokus auf Russland begründet sich darin, dass das Land beim Einsturz des Kali-Kartells stark im Rampen-licht stand. Bei zwei der drei exportierten Düngemittelgüter hat Russland einen...
Article
Russia emerged as an important wheat exporter in recent years raising the question of how this will affect international wheat markets. In particular developing countries – the main destination of Russian wheat exports – could be harmed by aggressive pricing behaviour. This article analyses the exertion of price discrimination by Russian wheat expo...
Article
This study discusses two widely used approaches in the New Empirical Industrial Organization (NEIO) literature and examines the strengths and weaknesses of the Production-Theoretic Approach (PTA) and the General Identification Method (GIM) for the econometric analysis of market power in agricultural and food markets. We provide a framework that may...
Article
Full-text available
Substantial changes in the world wheat market have resulted in a shift in the market shares of the main wheat exporting countries. Since 2002, Kazakhstan, Russia, and Ukraine (KRU) have become important wheat exporters on the world market, and their pricing behavior has become a vital issue. By applying the pricing-to-market model to wheat exports,...

As a result of some important changes in the international wheat market, market shares of leading exporters have recently altered. The Black Sea region countries – Kazakhstan, Russia and Ukraine have become important wheat exporters. Consequently, the pricing behavior of these countries has become a key issue. By applying the pricing-to-market mode...
Article
Transition was characterized by massive structural changes in most economic sectors in Ukraine. This is especially true for the dairy sector. Several countervailing developments took place under transition that affected the dairy industry. Interregional trade became feasible, the importance of milk delivered by households increased significantly, a...

Weizen stellt weltweit nach wie vor eine der wichtigsten Grundlagen der menschlichen Ernährung dar. Dies gilt besonders für Zentralasien, dort wird pro Kopf doppelt so viel Weizen wie in Deutschland verbraucht. Im Durchschnitt lag der Selbstversorgungsgrad der globalen Weizenproduktion zwischen 1990/01 und 2013/14 bei knapp über 100%. In den zentra...
Article
The objective of this study is, based on the existing literature, to provide a general systematic characteristic of market structure models. We distinguish cost, production, profit, revenue functions, as well as the general identification approach as most plausible methods to measure the degree of market power. Using time-series data of the Ukraini...
Article
Traditionally, the international wheat market has been considered a good example of a market with perfect competition. Yet, several articles provide evidence of imperfect competition and price discrimination in the wheat trade. However, these studies focused on traditional high-quality wheat exporters such as Canada and the United States. In contra...

Full-text available
Are Eastern European agricultural markets working? Beware of state-prescribed market interventions! Substantial danger exists that politically prescribed market inter-ventions, designed to counter a supposed failure of the markets, will leave markets functioning worse rather than better. This is particularly true of Eastern European transition coun...

The objective of this paper is to provide an alternative model which can be used to test for oligopsony market power applying plant-level data. For this purpose, we took into account empirical studies and specific developments in the Hungarian dairy industry and specified a model that provides useful benchmarks for an econometric test of market pow...
Article
Full-text available
This study develops a structural market model for the econometric analysis of buyers’ market power in the Ukrainian meat processing industry, because there is some evidence that suggests that meat processors may excise market power in the agricultural market of slaughtered livestock. The estimation results did not produce any evidence suggesting th...
Article
Significant changes have taken place in the world wheat market in the last decade. Russia, a former net wheat importer, has become a leading exporter with a world market share of 11.2% in 2009. This increasing importance and the discussion about the establishment of a grain-OPEC consisting of Ukraine, Kazakhstan and Russia has raised the issue of p...

Significant changes have taken place on the world wheat market over the last decade. Russia, a former net wheat importer has become a leading exporter with a world market share of 13.8 percent in 2009/2010. Though there are several studies on the pricing behaviour of Canadian and US wheat exporters, there is none on the pricing behaviour of Russian...
Article
A structural market model is estimated to analyze the effect of market power on resource allocation in the Hungarian pork supply chain. Regression analysis suggests that market power exists, though at a relatively low level. Moreover, the estimates show that processors might pursue Cournot strategies. In addition, we observe that market power of pr...

Article
Full-text available
In recent years increasing number of contractual arrangements in food chains are observed. There are several reasons for this phenomenon. Improving food quality often requires significant specific investments. Given high asset specificity, investors find it difficult to appropriate the returns on investment and thus have incentives to integrate. Ho...

Article
Full-text available
Transition from the planned to the market economy involved profound changes in Ukrainian economy. Before the liberalization of prices in 1992, milk processing in Ukraine was concentrated in regionally distributed large state milk processing factories. In the meantime, the dairy sector has been privatized. However, the emerging privatization forms w...
Article
Full-text available
Most of the studies based on the New Empirical Industrial Organization (NEIO) approach use the industry data to estimate the degree of market power at the national level. Yet, only a few empirical studies presented the results that measure the degree of market power at the regional level and found the existence of market power in the regional marke...
Article
Full-text available
The objective of this paper is to provide an analysis of potential market power in the Ukrainian meat supply chain. Many agricultural Economists find evidence of oligopsony power in the meat packing industry. These studies are typically done for industries in developed market economies and have largely focused on the US and European meat sectors. H...

The research project MATRACC investigates wheat markets in the Caucasus and Central Asia and the major supplier countries of this region, namely Kazakhstan, Russia and Ukraine (KRU) against the background of the on-going global food crisis. Long-term rising prices and increasing price volatility on the world markets for agricultural raw materials have considerably affected the countries in Central Asia and the Caucasus. However, until today research has more or less neglected the impact of the global food crisis on this region. There is nearly no empirical evidence on how wheat markets in this region work and how prices are formed. The present research project wants to close this research gap. Three different but closely connected working groups will carry out empirical analyses on price transmission and price volatility, structure of the wheat supply chains, and wheat trade patterns and relationships. Besides providing empirical results on important research questions, this project will also contribute to capacity-building in the countries under consideration. The PhD students coming predominantly from the CCA countries will not only benefit from working in an international research team consisting of IAMO researchers and well-known scientists in the relevant field of research but also from taking part in graduate courses and PhD workshops. The MATRACC project is supported by the Volkswagen Foundation and runs over the three-year period 2012-2017.

Project
The primary goal of the project is the further development and the stronger internationalization of the research and education landscape in Ukraine, in particular in agricultural and food economies. The project consists of four closely linked components. First a joint research group will be created forming the core of the project and dealing with questions of embedding the Ukrainian food economy into regional and international markets. In addition, the second component contains capacity building actions at the Kyiv School of Economics (KSE) in Kyiv, Ukraine. These include summer schools, various seminars and workshops that are also open to students and teachers from other Ukrainian research institutions and universities. Research activities and capacity building actions are embedded in a project office at KSE, the third component of the project. The project office coordinates the cooperation between project locations, more specifically Germany (IAMO) and Ukraine (KSE), maintains the relations to other Ukrainian universities and coordinates the fourth component, the conceptual preparation of project continuation. Establishing a chair for "International Agricultural and Food Economy" at KSE is planned within the project beyond project funding. Perspectively, a research center is intended to be developed from this chair. https://www.iamo.de/en/research/projects/details/uafoodtrade/
