A Model of Diffusion of Genetically Modified Crop Technology in Concentrated Agricultural Processing Markets - The Case of Soybeans AgEcon
Nadolnyak, Denis A.; Sheldon, Ian M..
In the paper, a dynamic model of diffusion of genetically modified crop technology is developed and simulated using the U.S. soybean market data. The model accounts for factors specific to agricultural markets, such as oligopsony power and strategic interaction among crop processors, growers' characteristics such as adoption behavior, and identity preservation requirements. Simulation results show how these factors affect the magnitude and distribution of the potential gains from genetically modified crops.

Dynamic Assessment of Bertrand Oligopsony in the U.S. Cattle Procurement Market AgEcon
Ji, In Bae; Chung, Chanjin.
The new empirical industrial organization approach with the Bertrand model is employed to measure the oligopsony market power in the U.S. cattle procurement market. The assumption of price competition (Bertrand model) based on the nature of cattle production such as cattle cycle and seasonality is used and compared to quantity competition (Cournot model). The empirical results show that the oligopsony market power exists in the U.S. cattle procurement market. The cattle cycle and seasonality affect the oligopsony market power and the cattle cycle causes the change of market power. However, concentration has a negative effect on the oligopsony market power.

Imperfect Competition in the Fresh Fruit and Vegetable Industry AgEcon
Requillart, Vincent; Simioni, Michel; Varela Irimia, Xose Luis.
Do retailers exert market power in the fresh fruit and vegetables markets? In the EU countries, as the retail industry distributes a significant part of fruit and vegetables, a non competitive behavior might have significant impact on consumption, on surplus and welfare. In this paper, we shed some light on the degree of non-competitive distortions in the French fresh fruit and vegetable markets. We analyze the market of tomato. The analysis is based on aggregate data on final consumption and prices at both shipper and consumer levels in France. The structural model is composed of a system of demand equations, supply equations and pricing equations which include terms that capture the oligopoly and oligopsony power of the retail sector and that account for...

Imperfect competition in the fresh tomato industry AgEcon
Requillart, Vincent; Simioni, Michel; Varela Irimia, Xose Luis.
In this paper, we analyse the market power of the retail industry in the French tomato market. Following the methods developed in the New Empirical Industrial Organization, we develop a structural model of this industry. The analysis is based on detailed data on final consumption and prices at both shipper and consumer levels for two types of tomatoes in France. The structural model is composed of a system of demand equations, supply equations and pricing equations which include terms which capture the oligopoly and oligopsony power of the retail sector. We show that i) elasticity of demand varies during the year ii) the retail sector exercise only a ‘moderate’ market power iii) the exercise of market power decreases over time iv) If markets were...

IS 'GETTING THE PRICES RIGHT' ALWAYS RIGHT? HOW TRADE LIBERALIZATION CAN FAIL AgEcon
Gaitan, Beatriz; Pavel, Ferdinand.
We present a general equilibrium model with oligopsonistic market structure in one of the sectors. Buyers of inputs can set the price of inputs by being involved in rent seeking activities. The framework developed is applied to the Bulgarian economy in particular to the agro-food chain. From the application to the Bulgarian economy we find that if there are market imperfections, such as oligopsonistic behavior in the economy, there are no significant welfare gains from free trade. Significant welfare gains from trade are observed only when a competitive structure prevails. We show that eliminating this market imperfection can bring important welfare implications and an efficient reallocation of resources.

Location and Spatial Pricing in Agricultural Markets AgEcon
Graubner, Marten; Balmann, Alfons; Sexton, Richard J..
Agricultural markets often feature significant transport costs and spatially distributed production and processing which causes spatial imperfect competition. Spatial economics considers the firms’ decisions regarding location and spatial price strategy separately, usually on the demand side, and under restrictive assumptions. Therefore, alternative approaches are needed to explain, e.g., the location of new ethanol plants in the U.S. at peripheral as well as at central locations and the observation of different spatial price strategies in the market. We use an agent-based simulation model to analyze location and spatial pricing in a general model under multi-firm competition, two-dimensional space, and a continuum of potential price strategies. The...

MODELING PRICE IMPACTS OF BACKWARD VERTICAL INTEGRATION IN THE US PORK INDUSTRY AgEcon
Pritchett, James G.; Liu, Donald J..
The U.S. pork sector is evolving from an industry of small, independent firms vertically linked by spot markets to one of substantially larger firms vertically connected through contractual agreements and integration. Potential benefits to this tighter vertical arrangement include lower consumer pork prices, although the true nature of this benefit is still under debate. At the same time, there is concern of market foreclosure because highly vertically integrated industry may prevent independent hog producers from having access to open markets in which to sell their output. The objective of this paper is to develop an econometric model to estimate the extent of backward integration by pork processing firms into the upstream hog production stage, taking...

Oligopoly and price transmission in Turkey’s fluid milk market AgEcon
Tekguc, Hasan.
Farmers and consumers suspect that processing firms abuse their power in the milk marketing chain. We employ threshold autoregressive and moment threshold autoregressive tests and contrary to expectations find evidence of a downward trend in UHT milk real price without a corresponding decline in farm-gate prices. The downward trend coincides with increased competition in the dairy industry and with the growing market share of the formal sector at the expense of the informal sector. Major dairy processing firms expand their market share and still enjoy healthy profits thanks to increasing returns to scale in processing and distribution in a growing market.

Oligopsony/Oligopoly Power and Factor Market Performance: The Case of U.S. Old Newspapers AgEcon
Hervani, Aref A..
This paper derives price-cost margins for the old newspaper (ONP) input market for newsprint manufacture and then examines the effects of two government policies and two variables measuring the market performances of ONP input and newsprint output on the oligopsonist’s ONP price-cost margins. In the wastepaper recycling market in particular, the ONP input market has not been successful in using the ONP generated. The outcomes of the study are that various degrees of price distortions existed in the ONP input markets in four regions of the United States during 1972-1995. Demand-side policy had a positive effect and supply-side policy had a negative effect on ONP price-cost margins in all regions.

Price Competition with Particle Swarm Optimization: An Agent-Based Artificial Model AgEcon
Zhang, Tong; Brorsen, B. Wade.
This study instructs an artificial price competition market to examine the impact of capacity constraints on the behavior of packers. Results show when there are cattle left for the lowest bidder after all other packers finishing their procurement, the capacity constraints make the price lower than the perfect competition level.

Regulatory Institutions in Agricultural Markets: A Comparative Analysis AgEcon
Sorensen, Ann-Christin; Tennbakk, Berit.
We have employed a simple model to analyse market regulation in a situation with multifunctional agricultural production, i.e., a public good produced jointly with a private good, and where there is imperfect competition in processing. We have analysed the impact on welfare of two archetype regulatory institutions formed to overcome the market imperfections. The institutions, a Regulatory Marketing Board and a Regulatory Marketing Cooperative, are both represented in the Norwegian agricultural market. Taking into account the cost of public funds, we find that the Board in general ensures the highest social welfare. The Cooperative does not replicate the Board solution unless restricted by a price cap and in combination with a production subsidy. If the...

Spatial Competition of Milk Processing Cooperatives in Northern Germany AgEcon
Huck, Petra; Salhofer, Klaus; Tribl, Christoph.
In this paper we develop a theoretical model of competition among marketing cooperatives (co-ops) in a spatial market setting assuming uniform delivered pricing and Loschian conduct. The model is an extension to Alvarez et al.'s (2000) spatial competition model for investorowned firms (IOF). Theoretical results include i) that the prices for raw milk are, ceteris paribus, higher in a pure market of coops than in a pure IOF market; ii) that even coops may imperfectly transmit price changes upstream; and iii) that the price farmers receive for their raw product is a function of economic space (distance times transportation costs) between coops. We test our theoretical findings for milk processing co-ops in Northern Germany using data of monthly average...

TRADE POLICY AND TIME CONSISTENCY IN AN OLIGOPSONISTIC WORLD MARKET AgEcon
Gervais, Jean-Philippe; Lapan, Harvey E..
This paper investigates the strategic behavior between countries that have purchasing power on the world market for a certain good. Tariffs and quotas are not equivalent protection instruments in this oligopsonistic market. Policy active importers would be better off by colluding and setting their trade instrument cooperatively. In a non-cooperative setting, if production decisions occur before consumption decisions, the ex-ante optimal policy is not time consistent because the ex-post elasticity of the residual foreign export supply curve is lower than the ex-ante elasticity. However, we show that the importers' inability to irrevocably commit to their trade instrument may be welfare superior to the precommitment solution. The negative welfare...
