MEASURING AN ALMOST IDEAL DEMAND SYSTEM WITH GENERALIZED FLEXIBLE LEAST SQUARES AgEcon
Poray, Michael C.; Foster, Kenneth A.; Dorfman, Jeffrey H..
Structural change in meat consumption has been the focus of many researchers during the last two decades. In this paper we develop a dynamic linear Almost Ideal Demand System (AIDS) model from a cost function that allows for time varying parameters. This model is consistent with inertia in the parameters of the cost and indirect utility functions. It allows for persistent preferences which may arise from cultural biases, lifestyles, peer pressure, etc. An empirical application is conducted with US meat consumption and price data using a generalized system of flexible least squares, Generalized Flexible Least Squares (GFLS). GFLS allows parameters to evolve slowly over time through incorporating of penalties in fluctuations. Estimated quarterly...

Production Structure, Technological Change and Scale Economies in the Saw and Planing Mills Industry in New Brunswick, Canada AgEcon
Yigezu, Yigezu A.; Foster, Kenneth A.; Lantz, Van.
The translog cost function approach is employed to characterize the production structure and to estimate the rate of technical change and technical bias in the saw and planing mills industry (SPM) in the New Brunswick Province. The findings are that the production structure of the saw and planing mills in Canada is neither homothetic nor homogenous implying potential scale induced distortion in the input mix. Morishma elasticity of substitution estimates show that in the existing technology of the saw and planing mills in New Brunswick, labor can more easily be substituted by capital than capital by labor. Moreover, the amount of round wood that is required to complement labor is higher than that required to complement energy and capital, which indicates...

Integrated On-Farm Decision Making: Economic Implications of Increased Variation in Litter Size AgEcon
Widmar, David A.; Olynk, Nicole J.; Richert, Brian T.; Schinckel, Allan P.; Foster, Kenneth A..
Increased litter sizes and associated piglet performance consequences, challenge swine producers. Stochastic modeling captured bioeconomic performance of individual piglets. As average litter size increased from 8.8 to 20.8 piglets, costs and revenues per head marketed from the demonstration herd decreased and total profit increased at a decreasing rate.

Evaluation of the Substitutability between U.S. and Canadian Softwood Lumber AgEcon
Roman, Angel Aguiar; Foster, Kenneth A.; Shook, Steve.
Softwood lumber trade between the United States and Canada has worldwide attention due to its economic importance and for lengthy dispute. Most studies have focused on welfare effects of the dispute, while few studies have evaluated the question of likeness of product. This study evaluates the substitutability between U.S. and Canadian softwood lumber including other countries'’ softwood lumber. Price elasticities are derived from the linear approximation of the Almost Ideal Demand System. The results show that softwood lumber imports to the U.S. from various countries are indeed substitutes for U.S. softwood lumber. The Morishima elasticities of substitution indicate that other countries have a higher degree of substitutability than Canadian softwood...

Productivity Growth and Convergence in Crop, Ruminant and Non-Ruminant Production: Measurement and Forecasts AgEcon
Ludena, Carlos E.; Hertel, Thomas W.; Preckel, Paul V.; Foster, Kenneth A.; Nin Pratt, Alejandro.
There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of productivity growth in agriculture is an essential input. Yet solid projections for this variable have proven elusive – particularly on a global basis. This is due, in no small part, to the difficulty in measuring historical productivity growth. The purpose of this paper is to report the latest time series evidence on total factor productivity growth for crops, ruminants and non-ruminant livestock, on a global basis. We then follow with tests for convergence amongst...

INDIRECT UTILITY FUNCTIONS AND TESTABLE CONDITIONS AgEcon
Detre, Joshua D.; Foster, Kenneth A..
We develop testable hypotheses for utility maximization given risk averse producers based on a general specification of the utility function. This is a direct expansion of the model posed by Pope (1978). Empirical tests using production data with a translog specification indicate that utility maximization does not always hold.

ECONOMIC REPLACEMENT OF A HETEROGENEOUS HERD AgEcon
Boys, Kathryn A.; Li, Ning; Preckel, Paul V.; Schinckel, Allan P.; Foster, Kenneth A..
A model was developed and used to determine the optimal slaughter weights of pigs with heterogeneous growth raised in a 1,000 head barn and marketed in truckload groups. Explicitly recognizing the heterogeneity of pig weights and marketing the herd over time in truckload batches can substantially increase profit.

DOES RURAL JOB GROWTH LEAD THE ECONOMY OUT OF RECESSION? AgEcon
Golub, Alla A.; Henderson, Jason R.; Foster, Kenneth A..
This paper explores the dynamics of rural and non-rural job growth to investigate if job growth starts in rural places, making it one of the leading indicators of economic growth. Empirical results provide mixed evidence. The mixed results of the Granger non-causality tests could be sensitive to the non-rural area definition. The relationship between rural job growth and non-rural job growth is not restricted to post-recession periods. Analysis of Bureau of Labor Statistics data suggests the spillover effects of non-rural growth are larger than the spillover effect of rural growth on non-rural areas. But this positive response of rural growth disappears over time and turns sharply negative. In the long run, “"backwash”" effects outweigh “"spread”" effects.

THE IMPACT OF HEALTH INFORMATION AND DEMOGRAPHIC CHANGES ON AGGREGATE MEAT DEMAND AgEcon
Schroeter, Christiane; Foster, Kenneth A..
Over the past few decades, U.S. meat consumption patterns have changed. Food consumption patterns are influenced by changing demographic characteristics, changing lifestyles, increasing health, and nutrition concerns. Prior research suggests that these factors have significant influence on the demand for meat (Capps and Schmitz; Kinnucan, Hsia, and Jackson). By incorporating a demographic and a health information variable in the meat demand system, this study aims to quantify and interpret important non-price determinants of meat demand. Demographic and health information variables might act as demand shifters in the model. Evaluating the effects of changes on meat demand delivers information on the potential existence of structural change in the...

RISK PREFERENCES AND CONTRACTING IN THE U.S. HOG INDUSTRY AgEcon
Johnson, C. Scott; Foster, Kenneth A..
Much of the increase use of vertical coordination in the U.S. swine industry has taken place through contract production. While the incidence of contracting is much higher in nontraditional hog production areas, a growing number of Midwestern producers are being faced with contract options. A variety of contractual arrangements are available through feed companies, integrators, genetics firms, and packers. However, little is known about the profitability and risk characteristics of these alternatives. This research suggests that risk neutral producers in the Midwest would prefer independent production, and risk averse producers would prefer to choose among the various types of coordination arrangements.

NUTRITION AND THE ECONOMICS OF SWINE MANAGEMENT AgEcon
Boland, Michael A.; Foster, Kenneth A.; Preckel, Paul V..
Current methods of formulating animal rations lead to excess nutrient excretion which can potentially lead to excess manure nutrients and an increase in economic costs. These methods do not recognize the impact of diminishing returns. The objective is to simultaneously optimize feed ration composition and replacement. The results, when compared against results from a survey of feed companies, indicate that using a profit maximization rather than live weight growth maximization criterion targets nutrients to an animal's actual needs and, hence, fewer nutrients are excreted and higher returns for producers are obtained.

PREFERENTIAL TRADE OF AGRICULTURAL COMMODITIES IN THE CARIBBEAN BASIN AgEcon
Loper, Nathan; Abbott, Philip C.; Foster, Kenneth A..
Preferential agricultural trade under the Caribbean Basin Initiative has been beneficial to participating countries, particularly for differentiated goods. Goods that have not performed well were either subject to policy changes, eroding preferences and deteriorating market trends or structural changes that diminished CBI exports.

Mitigating the Compliance Cost of a Phosphorus-Based Swine Manure Management Policy AgEcon
Yap, Crystal; Foster, Kenneth A.; Preckel, Paul V.; Doering, Otto C., III; Richert, Brian T..
Regulatory changes by federal and state agencies portend a switch from nitrogen-based livestock manure disposal policies to phosphorus-based policies. This paper estimates the compliance costs of such a policy change for a hypothetical hog-grain farm in North Central Indiana. The farm includes 1,500 acres of cropland and has the capacity to raise 11,970 grow-finish hogs annually. The farm model also as the potential to produce four different crops on six different land types. A nonlinear math-programming model was developed to determine the optimal mix of management activities for a phosphorus-based regulation. The model allows mitigation of compliance costs via the choice between four different pig diets, three alternative methods of manure disposal,...

DEVELOPMENT OF A STOCHASTIC MODEL TO EVALUATE PLANT GROWERS' ENTERPRISE BUDGETS AgEcon
Ludena, Carlos E.; McNamara, Kevin T.; Hammer, P. Allen; Foster, Kenneth A..
Increased domestic concentration and international competition in the floricultural industry are forcing growers to improve resource management efficiency. Cost management and cost accounting methods are becoming key tools as growers attempt to reduce costs. These tools allow growers to allocate costs for each crop, increasing their greenhouse planning abilities. Growers have a relative high degree of risk due to potential crop and market failure. Individual growers have different tolerance for risk and risk bearing capacity. Growers need a cost accounting system that incorporates production and market risk, a system that allows them to make informed business decisions. The research reported in this paper developed a greenhouse budgeting model that...

Technical Efficiency among Organic and Conventional Farms in Sweden 2000-2002: A Counterfactual and Self-Selection Analysis AgEcon
Larsen, Karin; Foster, Kenneth A..
Technical efficiency and its determinants among organic and conventional farms in Sweden are analyzed for time-period 2000-2002. In addition, we address the issues that arise when comparing performance measures among the two groups of producers (conventional and organic) due differences in their technologies and the potential presence of self-selection in the farmer's choice of using conventional or organic production methods. If the choice of production method is based on, or at least in part based on, the farms expected productivity in organic and conventional farming respectively there is self-selection present that must be considered. We apply an endogenous switching regression model suggested by Lee (1978) to compare efficiency measures between the...

CHARACTERISTICS OF U.S. VEAL CONSUMERS AgEcon
Henderson, Jason R.; Foster, Kenneth A..
In response to a steady decline in U.S. veal consumption, veal producers have responded by searching for new demand opportunities. Results from descriptive analysis and a probit model of veal consumer characteristics indicates that veal is typically consumed away from home by an older, caucasian, male professional living in a metropolitan area in the Northeast. Promotion programs targeting this demographic group may provide limited gains. Promotion strategies that target consumers in other geographic regions and demographic groups for at home consumption could potentially lead to larger gains in veal consumption.
