IDENTIFYING IMPLICIT COLLUSION UNDER DECLINING OUTPUT DEMAND AgEcon
Weliwita, Ananda; Azzam, Azzeddine M..
The "trigger price" oligopoly model is used to develop a test for oligopolistic as well as oligopsonistic conduct by observing how an industry responds to unexpected declines in output demand. The hypothesis that U.S. beef packers maintain cooperative pricing strategies is rejected.

Management Practices and Financial Performance of Agricultural Cooperatives: A Partial Adjustment Model AgEcon
Azzam, Azzeddine M.; Turner, Michael S..
This paper uses the Nerlovian partial adjustment model to test the hypothesis that the rate of a cooperative's adjustment to a desired financial position is partially determined by its management practices. The results indicate that management practices that are board responsibilities are not contributing to the speed of adjustment in reaching the desired financial performance, which is the responsibility of the board of directors. But management, when independently pursuing management's responsibility or when working with that board on shared responsibility, does contribute to the speed of adjustment toward the desired financial goal.

Ethanol and Meat in the U.S.: A Multi-Market Analysis AgEcon
Bhattacharya, Suparna; Azzam, Azzeddine M.; Mark, Darrell R..
Since corn is the primary feedstock used for producing ethanol in the U.S., and ethanol production yields byproducts that can be fed to livestock in combination with corn, addressing the effect of ethanol production on meat markets should consider not only demand and supply interdependence between corn, ethanol, and ethanol byproducts; but also demand and supply interdependence between different types of meats. This paper develops a multi-market equilibrium displacement model to account for the interdependence. Six markets are considered: beef, pork, poultry, corn, ethanol, and ethanol byproducts. Results show that poultry is the most sensitive to ethanol production, followed by beef and pork.

Imperfect Competition and Total Factor Productivity Growth in U.S. Food Processing AgEcon
Azzam, Azzeddine M.; Lopez, Elena; Lopez, Rigoberto A..
This article examines the role of imperfect competition in determining total factor productivity growth (TFPG) by bringing together a New Empirical Industrial Organization (NEIO) model and the TFPG model of Nadiri and Mamuneas (1998). Applying the integrated model to 1973-92 data from 29 food processing industries revealed that changes in markups, economies of scale, and demand growth contributed positively to TFPG while the disembodied technical change was a negative contributor. Furthermore, the TFPG estimates are starkly different from the conventional (Solow's residual) TFPG measures, underscoring the need to account for imperfect competition, returns to scale, and demand in analyses of this type.

Market Power and/or Efficiency: An Application to U.S. Food Processing AgEcon
Lopez, Rigoberto A.; Azzam, Azzeddine M.; Liron-Espana, Carmen.
This article separates oligopoly-power and cost-efficiency effects of changes in industrial concentration and assesses their impact on output prices in 32 food-processing industries. Empirical results indicate that although concentration induces cost efficiency in one-third of the industries, oligopoly-power effects either dominate cost efficiency or reinforce inefficiency, resulting in higher output prices in most industries. The article also provides fresh econometric estimates of oligopoly power and economies of size for the industries in question.

Environmental Regulations and the Structure of U.S. Hog Farms AgEcon
Nene, Gibson; Azzam, Azzeddine M.; Schoengold, Karina.
The U.S hog production industry has been continually subjected to rapid structural changes since the early 1990s. The industry's move towards more concentrated large hog farms and geographical concentration of such farms, have triggered public concerns over the dangers such big animal feeding operations are likely to pose to the waters of the country. This study investigates the implications of state-level environmental regulations on the structure of hog farms. The results of this study suggest that environmental regulations will result in one of three possible scenarios: (1) a more competitive industry in which small hog operations are not adversely affected which will allow more small operations to enter rather than exit the industry; (2) a more...

A CAUTIONARY NOTE ON POLYNOMIAL DISTRIBUTED LAG FORMULATIONS OF SUPPLY RESPONSE AgEcon
Azzam, Azzeddine M.; Yanagida, John F..
This paper uses the Pagano-Hartley procedure to estimate the lag length and polynomial degree for the case of a quarterly hog supply equation. The results show that the nicely humped shapes which materialize when using the Almon lag may be caused by the failure in accounting for autocorrelation in determining lag length and polynominal degree.

IMPLICATIONS OF INCREASED REGIONAL CONCENTRATION AND OLIGOPSONISTIC COORDINATION IN THE BEEF PACKING INDUSTRY AgEcon
Azzam, Azzeddine M.; Schroeter, John R..
This article proposes an oligopsony pricing model for projecting the effects of increased concentration or oligopsonistic coordination in beef packing using simulation methods. The model combines an explicit behavioral theory of packing firms with an attempt to respect the regional scope of cattle procurement markets. Our results indicate less danger of falling cattle prices, as a results of increase packer concentration or coordination, than do results from conventional econometric studies.

Testing for Oligopoly and Oligopsony Power AgEcon
Azzam, Azzeddine M.; Pagoulatos, Emilio.
This paper extends the conjectural approach in industrial organization to the analysis of imperfections in output and factor markets simultaneously. Starting from the specification of a production function, the econometric analysis is based on the formulation and estimation of a simultaneous equation model consisting of a production function, first order conditions associated with factor employment, and two conjectural elasticities to parametrize the industry's oligopoly and oligopsony equilibria. As an example, we provide an application to the U.S. meat packing industry. Our results suggest that the industry excercised market power in both the output (meat) market and the factor (live animals) market.
