ASSESSING THE IMPACT OF A HOG SLAUGHTER PLANT CLOSING: THE THORN APPLE VALLEY CASE AgEcon
Raper, Kellie Curry; Cheney, Laura Martin; Punjabi, Meeta.
In 1998, Thorn Apple Valley ceased slaughter operations at its Detroit, Michigan plant, the state's only major hog packing facility. We examine the plant closing's local impact via an investigation of whether prices received by Michigan hog producers decreased relative to hog prices in the Eastern Corn Belt.

Commodity-Procurement Strategies of Food Companies: A Case Study AgEcon
Jones, Kraig M.; Raper, Kellie Curry; Whipple, Judith M.; Mollenkopf, Diane A.; Peterson, H. Christopher.
This research evaluates the main characteristics considered in commodity-procurement decisions made by food manufacturers. Procurement characteristics are examined and a framework is developed which classifies procurement characteristics into three categories: product constraints, company constraints, and service constraints. A case-study approach is used to determine the importance of various procurement characteristics and their impact on the buyer’s procurement-mechanism choice. The research also examines the strategic role that a commodity-procurement department plays within a corporation and how that role relates to the three commodity-procurement decision classifications.

CYCLICAL CONCENTRATION AND BIOTECH R&D ACTIVITY: A NEO-SCHUMPETERIAN MODEL AgEcon
Oehmke, James F.; Wolf, Christopher A.; Weatherspoon, Dave D.; Naseem, Anwar; Maredia, Mywish K.; Raper, Kellie Curry; Hightower, Amie L..
Several characteristics of biotech industry structure follow cyclical patterns. Mergers and acquisitions activity shows cyclical behavior, with peaks from 1988-92 and 1996-97 and a valley from 1993-95. The ratio of large-firm to small-firm field trials, and the Herfindahl-Hirshmann concentration index, move pro-cyclically with M&A activity. This paper develops a formal, dynamic, neo-Schumpeterian model of endogenous R&D and innovation. The model generalizes and extends the literature on biotech industry concentration. For specified parameter values, the out-of-steady-state dynamics are examined, and shown to generate model behavior which is consistent with empirical descriptions of biotech concentration and R&D-activity cycles.

Demographic Factors Affecting the Adoption of Multiple Value-Added Practices by Oklahoma Cow-Calf Producers AgEcon
Williams, Brian R.; Raper, Kellie Curry; DeVuyst, Eric A.; Peel, Derrell S.; Lalman, David L.; Richards, Chris; Doye, Damona G..
The utilization of marketing programs to enhance feeder calf value has been met with modest success in Oklahoma. Value-added programs are continually promoted as avenues for improving cow-calf profitability, but producer adoption of value-added practices lags in spite of research showing the value of these practices. Identifying producer characteristics that increase their likelihood to adopt value-added practices is critical to developing successful outreach efforts. Results from a survey of Oklahoma producers on value-added practice adoption indicate that multiple demographic variables influence a producer’s likelihood of practice adoption. For Extension specialists, results can help in targeting likely adopters and developing methods to overcome...

Determinants of Price Differentials in Oklahoma Value-Added Feeder Cattle Auctions AgEcon
Williams, Galen S.; Raper, Kellie Curry; DeVuyst, Eric A.; Peel, Derrell S.; McKinney, Doug.
Many value-added practices cannot be observed by feeder cattle buyers. Third-party verification can decrease market inefficiency associated with this asymmetric information. We evaluate the effectiveness of a verification program, the Oklahoma Quality Beef Network, in increasing received prices. We estimate the value of verification, weaning, vaccinating, certification and phenotypic traits of feeder cattle at Oklahoma auctions. Results indicate that the OQBN program adds $2.39 to $5.74/cwt. Vaccinating calves adds $1.44/cwt, and weaning calves adds $2.05/cwt. Differential values for lot size, average weight, hide color, frame size, conditioning, Brahman influence, gender and other characteristics are also reported.

Determining Key Factors of Influence on the Profitability of Retaining Cull Cows Beyond Culling AgEcon
Amadou, Zakou; Raper, Kellie Curry; Ward, Clement E.; Biermacher, Jon T.; Cook, Billy.
Factors influencing the profitability of retaining and feeding cull cows beyond culling were investigated. First, a price response function is estimated using 19 years of monthly price data as reported by Agricultural Market Services (AMS). Net returns are then estimated using data from a three year cull cow feeding experiment conducted at The Samuel Roberts Noble Foundation and used to examine the relative effect of various factors on net returns. Results showed the importance of average daily gain increases across feeding periods while feeding system is also an important contributing factor to net returns.

DETERMINISTIC NONPARAMETRIC MARKET POWER TESTS: AN EMPIRICAL INVESTIGATION AgEcon
Raper, Kellie Curry; Noelke, Corinna M..
A review of recent literature reflects the development of several deterministic nonparametric market power tests. We use Monte Carlo experiments to evaluate the veracity of four monopolistic and four monopsonistic market power tests that use the deterministic nonparametric approach. The experiments are implemented using data from ten known market structures. When results are compared to Raper, Love, and Shumway's (1999) findings concerning parametric market power tests in the Bresnahan-Lau tradition, we find that the parametric tests perform well while only two of the nonparametric tests appear able to identify market power.

DISTINGUISHING THE SOURCE OF MARKET POWER: AN APPLICATION TO CIGARETTE MANUFACTURING AgEcon
Raper, Kellie Curry; Love, H. Alan; Shumway, C. Richard.
We compare nonparametric and nonstructural market power tests using data from the cigarette manufacturing industry. Tests are implemented to examine both monopoly and monopsony power exertion by cigarette manufacturers. Results indicate that market power in the tobacco industry, previously attributed to monopoly power exertion, should at least in part be attributed to monopsony market power in the upstream tobacco market.

Economic Effects of Bovine Respiratory Disease on Feedlot Cattle during Backgrounding and Finishing Phases AgEcon
Brooks, Kathleen R.; Raper, Kellie Curry; Ward, Clement E.; Holland, Ben P.; Krehbiel, Clint.
This research examines the economic effects of bovine respiratory disease (BRD) on backgrounding and finishing phases of cattle production. This research measures the effectiveness of using serum haptoglobin (Hp) concentration to predict BRD occurrence and the impact of multiple treatments for BRD infection on cattle performance and returns. During the backgrounding phase, 222 heifers were grouped by Hp level. After the backgrounding phase, 193 heifers were then grouped by number of BRD treatments in the finishing phase. Net returns decreased in the backgrounding phase and the combined phases as the number of BRD treatments increased. Hp concentrations had no significant effects on net returns.

ESTIMATING IMPORT DEMAND IN THE MEXICAN CHEESE MARKET AgEcon
Ramirez, Miguel A.; Jones, Kraig M.; Arellano-Vaca, Juan Francisco; Raper, Kellie Curry.
Mexico is the fastest growing market for US dairy exports and it is the largest market for U.S. cheese. The U.S. has always enjoyed a large share of the Mexican cheese market. However, its share growth has been less dynamic than the share of Europe, Oceania and other countries, despite advantages in proximity, shipping costs, and delivery times. We use an Almost Ideal Demand System to estimate own and cross-price elasticities in the Mexican cheese import market to assess the comparative position of the U.S. relative to other cheese market participants.

Evaluating Food Commodity Procurement Strategies AgEcon
Jones, Kraig M.; Whipple, Judith M.; Raper, Kellie Curry; Mollenkopf, Diane A..
We use a case study approach to determine the primary factors affecting food manufacturers' commodity procurement decisions, as well as to examine the strategic nature of commodity procurement departments. The research fills a gap in both the commodity and procurement literature. A large literature exists on commodity marketing; however, very little exists on the topic of commodity procurement. Existing procurement literature tends to focus on non-commodity products rather than commodity products. The results suggest a model for the strategic role of commodity procurement departments within food manufacturers. The initial procurement strategy must be supply maintenance, which once accomplished, allows the commodity procurement department to progress...

Factors Affecting Adoption of Recommended Management Practices in Stocker Cattle Production AgEcon
Johnson, Rachel J.; Doye, Damona G.; Lalman, David L.; Peel, Derrell S.; Raper, Kellie Curry; Chung, Chanjin.
Binary logit regression models were used to estimate factors affecting adoption of recommended management practices. Variables analyzed include aspects of farm structure, human capital, farm objectives, and production system employed by the producer. Results reveal that operation size and dependency upon income from the stocker operation, in particular, influence the adoption of recommended practices. Older producers and those pursuing a year-round production strategy were found to lag in adoption.

FOOD SAFETY AND FRESH STRAWBERRY MARKETS AgEcon
Woods, Mollie; Thornsbury, Suzanne; Raper, Kellie Curry; Weldon, Richard N.; Wysocki, Allen F..
Consumer awareness of food safety issues is reshaping the retail food supply chain. For some retailers, public standards for food safety fail to provide the level of assurance demanded by their customers, so many are turning to private standards. Fresh strawberries have been implicated in food safety outbreaks resulting in clear decreases in short term demand. Shifts in production and consumption caused by the increased costs of adopting public or private food safety standards may reshape the fresh strawberry industry in the NAFTA region. Three scenarios of the adoption of food safety practices are analyzed using comparative statics and the outcomes of each scenario are discussed.
