2004 Michigan Dairy Grazing Farm Business Analysis Summary
Provedor de dados: 31
Autores: Wittenberg,   Eric; Wolf,   Christopher A.
This report summarizes the financial and production records of 10 dairy grazing farms from across Michigan. These 10 farms indicated that they grazed dairy cows at least three months of the year and that grazing provided more than 30 percent of the forage consumed during the year. To be included, the farms must have produced at least 50 percent of gross cash farm income from milk and dairy animal sales. The records came from Michigan State University's TelFarm project and the Farm Credit Service system in Michigan. The values were pooled into averages for reporting purposes. Farm records were checked for accuracy. While considerable variation in the data exists, average values are reported in the summary tables and discussion that follows.

THE POTENTIAL OF DAIRY FUTURES CONTRACTS AS RISK MANAGEMENT TOOLS
Provedor de dados: 31
Autores: Wolf,   Christopher A.; Berwald,   Derek K.
We examine the young dairy futures market as a risk management tool.  Using New York Board of Trade (NYBOT) data, we find that the BFP futures market is efficient and may potentially be a useful hedging tool.  However, we also find that competition from Chicago Mercantile Exchange (CME) contracts has significant detrimental effects on the NYBOT dairy futures contracts.  As a result NYBOT dairy futures contracts are likely to dry up.

A gravity model approach to forecasting tuberculosis transmission in cattle
Provedor de dados: 31
Autores: Xie,   Fang; Horan,   Richard D.; Wolf,   Christopher A.
Bovine tuberculosis (bTB) in cattle has caused significant economic losses to livestock producers and has proven difficult to eradicate.  It is suspected that cattle movement across different farms and regions is one of the key factors of bTB transmission in the United States. Prior attempts to model the epidemiology of bTB infection within cattle to predict disease transmission have not adequately captured the behavioral aspects of trade.  A better understanding of livestock trade patterns would help in predicting disease transmission and the associated economic effects. In this paper, we develop a gravity model of livestock trade and link it to an epidemiological model of bTB transmission, with the goal being that this information could lead to improved...

Optimal livestock diet formulation with farm environmental compliance consequences
Provedor de dados: 31
Autores: Hadrich,   Joleen C.; Wolf,   Christopher A.; Harsh,   Stephen B.
The current method to derive livestock diets is to optimize cost performance subject to animal performance and resulting nutritional requirements via a linear programming model.  In contrast, we examine the livestock diet formulation problem as a multi-criteria decision model with the criteria being cost performance, feed efficiency, and environmental compliance costs.  We find that there are many situations where farm financial situations are improved by feeding products with higher costs per unit of protein but lower phosphorus levels.

TECHNOLOGY VALUATION DISTRIBUTIONS WITH HETEROGENEOUS ADOPTERS
Provedor de dados: 31
Autores: Oehmke,   James F.; Wolf,   Christopher A.
This paper examines technology benefit allocation between an innovating firm and heterogeneous technology adopters.  Using a triangular distribution of adopter innovation value, we find that as the upper bound increases, optimal innovation price increases, but at a slower rate.  Similarly, as the lower bound decreases, price decreases and producer benefits increase. Finally, greater producer heterogeneity leads to greater producer benefits from innovation in non-competitive markets.   An empirical application of the model is considered, bovine somatotropin adoption on dairy farms.  The model generates an intuitive explanation of the common finding that average adopters are making zero or negative profits.

This paper examines the impact of European Union policy on genetically modified organisms on trade flows and economic growth.  Restrictive European Union policies on biotech production and consumption result in: an effective export subsidy of capital to the South; new trade flows; North America being the dominant producer of biotech research and development; the South being a dominant producer of biotech products; and the European Union being the dominant producer of traditional agricultural products.

Is Monsanto Leaving Money on the Table? Monopoly Pricing and Bt Cotton Value with Heterogeneous Adopters
Provedor de dados: 31
Autores: Oehmke,   James F.; Wolf,   Christopher A.
We examine the allocation of technology rents between a price-setting, innovating monopolist and heterogeneous technology adopters.  A model of monopoly pricing in the presence of heterogeneous adopters is used to examine conditions under which greater producer (farmer) heterogeneity leads to greater producer benefit from innovation in non-competitive markets.  An application to Bt cotton determines the profit-maximizing price of Bt cotton seed and reveals that Monsanto and Delta and Pine Land are indeed leaving money on the table in the form of unexploited profit opportunities.  However, we estimate that the presence of heterogeneous adopters explains over 80% of the rents that accrue to the farmers.

Verifying Credence Attributes in Livestock Production
Provedor de dados: 31
Autores: Olynk,   Nicole J.; Tonsor,   Glynn T.; Wolf,   Christopher A.
Livestock producers can respond to increasing consumer demand for certain production process attributes by providing verifiable information on the practices used. Consumer willingness to pay data were used to inform producer decision-making regarding selection of verification entities for four key production process attributes in the production of pork chops and milk. The potential for informing farm-level decision-making with information about consumer demand for product and production process attributes exists beyond the two products assessed as example cases in this analysis.

Voluntary Over-Order Milk Premium Agreements and Implications for Policy Choices
Provedor de dados: 31
Autores: Wolf,   Christopher A.; Banderob,   Duane A.
While policies define minimum farm-level milk prices based on end use, milk for fluid consumption is often priced above these minimums even in the presence of excess fluid quality milk. Cooperative action through marketing agencies-in-common facilities these over-order premiums. We examined the premiums that resulted from voluntary agreements in Michigan. The premiums enhanced farm price and offset minimum price variation. A critical consideration is the distribution of premiums across participants. Formal policies like state marketing orders and compacts may replace or complement voluntary premium agreements. As a replacement, these formal policies trade off flexibility in both premium level and distribution for stability.

CONTROLLING WILDLIFE AND LIVESTOCK DISEASE WITH ENDOGENOUS ON-FARM BIOSECURITY
Provedor de dados: 31
Autores: Horan,   Richard D.; Wolf,   Christopher A.; Fenichel,   Eli P.; Mathews,   Kenneth H., Jr.
The spread of infectious disease among and between wild and domesticated animals has become a major problem worldwide.  We analyze the socially optimal management of wildlife and livestock, including choices involving environmental habitat variables and on-farm biosecurity controls, when wildlife and livestock can spread an infectious disease to each other.  The model is applied to the problem of bovine tuberculosis among Michigan white-tailed deer.  The optimum is a cycle in which the disease remains endemic in the wildlife, but in which the cattle herd is depleted when the prevalence rate in deer grows too large.

DAIRY FARM DECISIONS ON HOW TO PROCEED IN THE FACE OF TB
Provedor de dados: 31
Autores: Nott,   Sherrill B.; Wolf,   Christopher A.
By early 2000, the number of commercial livestock herds in Michigan with bovine tuberculosis (TB) had increased to the point that policy makers were considering alternative ways to enable farmers to continue production with access to markets while eliminating TB and protecting the public's  health.  If at least one animal on a farm is found to have TB, a farmer currently has two choices about the future assuming the goal is to stay in the livestock business.  Alternative one is depopulation; all animals are removed to a state facility, slaughtered, and tested.  A new herd may be purchased after a state supervised clean up and waiting period is completed; this may take one year.  Alternative two is test and remove; a recurring series of testing is...

Aligning Incentives for Accelerated Heifer Growth in Custom Heifer Growing Contracts
Provedor de dados: 31
Autores: Olynk,   Nicole J.; Wolf,   Christopher A.
Dairy managers today are faced with the decision to either raise their own replacements on the dairy farm or send heifers to a custom heifer grower.  The largest potential challenge of contracting out the heifer raising enterprise revolves around the potential for a moral hazard problem because of hidden action on the part of the custom heifer grower.  A principal-agent framework was used to elicit contract terms which provide incentives for the custom heifer grower to perform accelerated growth without heifers becoming over-conditioned.  In order to provide incentives to custom growers, heifers returned to the dairy farm should be compared in performance to other heifers of similar age.  We solve for the price paid per pound of gain, price paid for inch...

Consumer Preferences for Animal Welfare Attributes: The Case of Gestation Crates
Provedor de dados: 31
Autores: Tonsor,   Glynn T.; Olynk,   Nicole J.; Wolf,   Christopher A.
Animal welfare concerns are having dramatic impacts on food and livestock markets. Here we examine consumer preferences for pork products with a focus on use of gestation crates. We examine underlying consumer valuations of pork attributes while considering preference heterogeneity as well as voluntary and legislative alternatives in producing gestation crate-free pork. Our results suggest that prohibiting swine producers from using gestation crates fails to improve consumer welfare in the presence of a labeling scheme documenting voluntary disadoption of gestation crates. Consumers are found to implicitly associate animal welfare attributes with smaller farms. Preference heterogeneity drives notably diverse consumer welfare impacts when pork produced with...

Livestock Disease Indemnity Design When Moral Hazard is Followed by Adverse Selection

Autores: Gramig,   Benjamin M.; Horan,   Richard D.; Wolf,   Christopher A.
Averting or limiting the outbreak of infectious disease in domestic livestock herds is an economic and potential human health issue that involves both the government and individual livestock producers. Producers have private information about preventive biosecurity measures they adopt on their farms prior to outbreak (ex ante moral hazard), and following outbreak they possess private information about whether or not their herd is infected (ex post adverse selection). We investigate how indemnity payments can be designed to provide incentives to producers to invest in biosecurity and report infection to the government, while simultaneously addressing the information asymmetry between producers and the government. We show how addressing the adverse selection...

OVER-ORDER PREMIUMS AND PRICE WARS IN THE MICHIGAN MILK MARKET
Provedor de dados: 31
Autores: Banderob,   Duane A.; Wolf,   Christopher A.
We examine behavior in the Michigan fluid milk market.  Over-order premiums exist because fluid milk demands are inelastic. Collusion by cooperatives is required to realize these profits.  In absence of collusion, the minimum prices defined by federal milk marketing orders prevails as excess fluid milk is always present.  Proprietary firms in Michigan joined the fluid milk cartel because of the threat of a state marketing order. Proprietary firms profits may be increased and information gathered in the short run through price wars that result when behavior deviates from collusion.

CUSTOM DAIRY HEIFER GROWING: SUMMARY AND ANALYSIS OF A 2001 GROWER SURVEY
Provedor de dados: 31
Autores: Wolf,   Christopher A.
While dairy farms have been increasing in size and specialization for decades, recent years have witnessed an acceleration of these trends.  As a dairy farm specializes in milking cows, other enterprises are often curtailed.  Management, labor, and capital constraints necessitate a movement towards outsourcing activities that were once a part of the smaller, but more diversified, dairy operation. One increasingly common example of outsourcing among dairy farmers is utilizing a custom replacement heifer grower.  By outsourcing the replacement heifer enterprise, a dairy farmer may free up labor, management, feed, or facilities for use by the milking herd.    As might be expected, an industry sub-sector has been created in response to the demand for custom...

Incorporating Environmentally Compliant Manure Nutrient Disposal Costs into Least-Cost Livestock Ration Formulation
Provedor de dados: 31
Autores: Hadrich,   Joleen C.; Wolf,   Christopher A.; Black,   J. Roy; Harsh,   Stephen B.
Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements. We incorporate nutrient disposal costs into a modified least-cost ration formulation model to arrive at a joint least-cost decision that minimizes the sum of feed and net nutrient disposal costs. The method is demonstrated with phosphorus disposal costs on a representative dairy farm. Herd size, land availability and proximity, crop rotation, and initial soil phosphorus content are shown to be important in determining phosphorus disposal costs.

The health and well being of all these animals depend heavily on relationships with veterinarians.  Veterinarians also contribute to public health through the FDA, CDC, USDA, and numerous other government agencies at the federal, state, and local levels.  Issues of primary concern include food safety, biosecurity, and the numerous emerging (and re-emerging) infectious diseases that are zoonotic in nature.

Recent high profile incidents and public debates in the United States have highlighted the increasing interest residents have regarding animal rearing and handling practices. This paper examines resident support for national legislation that mirrors Proposition 2, which in November 2008 passed in California. Results suggest perceptions regarding animal welfare information accuracy of livestock industry and consumer groups are particularly influential determinants of voting behavior and demand. The analysis also suggests residents may not fully appreciate price or tax implications when supporting additional animal welfare legislation. Implications for livestock industry and policy makers are provided along with suggestions for additional research.

As dairy farms grow and specialize in milking cows, raising replacement heifers is increasingly outsourced. Perhaps the largest challenge of outsourcing the heifer enterprise involves quality, measured as milk production potential, and the possibility for moral hazard due to hidden action on the part of the custom heifer grower. A principal-agent framework was used to elicit contract terms to provide incentives for the heifer grower to achieve desired growth rates, and enable the return of the heifer to the dairy farm on an accelerated time frame, without sacrificing quality.

Recent changes in dairy industry structure and policy have brought the role of cooperatives into question.  Analysis of milk marketing institutions and their association with cooperative marketing functions sheds light the interdependency of government involvement in milk marketing. We examine the role of cooperatives to determine whether cooperative market power can substitute for public policy power. The ability of cooperatives to maintain membership and balancing services depends critically on the dairy policies in place today.  In absence of milk marketing orders, we find it likely that cooperatives will be unable to maintain these services.

A Survey of Reproductive Management Strategies on US Commercial Dairy Farms
Provedor de dados: 31
Autores: Olynk,   Nicole J.; Wolf,   Christopher A.
Reproductive performance on the dairy farm affects the dairy’s profit because it directly affects milk production, the availability of replacements, the amounts of voluntary and involuntary culling, breeding costs, and costs associated with veterinary care (Britt, 1985).   Reproductive management programs selected for implementation differ across farms due to varying on-farm costs, such as labor costs, opportunity costs of management and labor, as well as facilities, farm goals and values, and management styles.  The objective of this paper is to summarize survey data in order to aid in providing economic insight into why varying types of farms utilize different methods of reproductive management and differing reproductive technologies.

As dairy farms grow and specialize in milking cows, one enterprise that may be removed from the dairy farm to allow for milk cow herd expansion is heifer raising.  Custom heifer raising is increasingly common across the country and purchasing heifers may be preferred to raising heifers.  However, these alternatives are not suitable for all dairy farmers.  In this article, we examine heifer enterprise costs relative to using a custom raiser or purchasing heifers.  We identify factors that should be considered in making the proper decision relative to the heifer enterprise.

Producer Livestock Disease Management Incentives and Decisions
Provedor de dados: 31
Autores: Wolf,   Christopher A.
This paper examines the economics of farm decisions to prevent and control infectious livestock disease. In the case of diseases with costly control tolerating some level of disease is often rational to the producer. Public policy intervention is based on future value and public good aspects of disease control which can lead to a discrepancy between private and public action thresholds. Producer incentives for disease management can be changed through new technologies that lower the cost of prevention or control, subsidies or cost sharing of control measures, or on the consumer side, a change in public desire for disease risk-free products that changes relative prices. Economists can incorporate appropriate epidemiology of a given disease in economic...

THE ECONOMICS OF MANAGING WILDLIFE DISEASE
Provedor de dados: 31
Autores: Horan,   Richard D.; Wolf,   Christopher A.
The spread of infectious disease among and between wild domesticated animals has become a major problem worldwide. Upon analyzing the dynamics of wildlife growth and infection when the disease animals cannot be identified separately from healthy wildlife prior to the kill, we find that harvest-based strategies alone have no impact on disease transmission. Other controls that directly influence disease transmission and/or mortality are required. Next, we analyze the socially optimal management of infectious wildlife. The model is applied to the problem of bovine tuberculosis among Michigan white-tailed deer, with non-selective harvests and supplemental feeding being the control variables. Using a two-state linear control model, we find a two-dimensional...

Understanding U.S. Consumer Demand for Milk Production Attributes
Provedor de dados: 31
Autores: Wolf,   Christopher A.; Tonsor,   Glynn T.; Olynk,   Nicole J.
A choice experiment was used to examine the value of various fluid milk attributes. Respondents were surveyed regarding half or whole gallon milk purchases. A split-sample design was used to examine consumer inferences regarding food safety. Willingness to pay for verification of production process attributes varied across attributes and verifying entity. Consumers were generally willing to pay substantial premiums for milk produced without the use of rbST, on local family farms, with assured food safety enhancement, and for these claims to be verified by the U.S. Department of Agriculture.

IS AGRICULTURAL RESEARCH STILL A PUBLIC GOOD?

Autores: Oehmke,   James F.; Weatherspoon,   Dave D.; Wolf,   Christopher A.; Naseem,   Anwar; Maredia,   Mywish K.; Hightower,   Amie L.
The nature of public agricultural research changed in 1980 when the Bayh-Dole Act allowed universities to retain title to inventions that were created with Federal funds, and the court case Diamond v. Chakrabarty allowed patenting of living tissue and eventually other bio-engineered products.  In 1997, over 2,300 new licenses and options were executed on academic life-sciences property.  This raises the questions agricultural research still be a public good?  This paper is a critical first step in understanding how increasingly private ownership of intellectual property affects the agribusiness environment and the evolving role of public agricultural research institutions.  The innovative step in this paper is the development of a formal economic model...

Consumer Willingness to Pay for Livestock Credence Attribute Claim Verification
Provedor de dados: 31
Autores: Olynk,   Nicole J.; Tonsor,   Glynn T.; Wolf,   Christopher A.
A choice experiment was used to determine consumer value for verification of livestock production process attributes. Willingness to pay for verification of production process attributes varied for both milk and pork chops across attributes and verifying entity. Statistically significant evidence of social desirability bias was found by comparing estimates of consumer preferences solicited using direct and indirect questioning. Indirect questioning may yield more accurate representations of consumer value than direct questioning, and therefore more accurate estimates for agribusiness decision making.

The emergence of agricultural biotechnology and policy responses to is altering global agricultural trade patterns.  This paper models the effects of restrictive policies concerning the production and consumption of genetically modified agricultural products.  The model relies on a Hecksher-Ohlin-Samuelson framework, adapted to include neo-Schumpeterian research and innovation.  The model includes two 'North' countries, the United States (US) and the European Union (EU), and the 'South'.  The EU is represented as prohibiting the production and consumption of biotech products, but not restricting biotech research relative to NA.  Model results include implications for economic growth, welfare, and trade patterns for the EU, US and S, given the restrictive...

Source Differentiated Mexican Dairy Import Demand
Provedor de dados: 31
Autores: Ramirez,   Miguel A.; Wolf,   Christopher A.
Mexico is a major destination of dairy exports and is the single largest importer of US dairy exports. We use a restricted source almost ideal demand system to estimate the demand for dairy products imported into Mexico. The estimation facilitates an examination of the demand for dairy imports and the results have implications for exporting firms and countries. Our estimates indicate fierce competition for the Mexican market between the US, Oceania, and “other countries” primarily from South America.

PROFITABILITY AND PRODUCTION EFFICIENCY OF THE CROP AND LIVESTOCK ENTERPRISES OF MICHIGAN DAIRY OPERATIONS: 1998 SUMMARY AND ANALYSIS
Provedor de dados: 31
Autores: Harsh,   Stephen B.; Wolf,   Christopher A.; Wittenberg,   Eric.
This paper summarizes the 1998 results of the Dairy Profitability and Production Efficiency project.  Among the major findings are that the average cost of production was almost exactly equal to the average milk herd revenue on a per hundredweight basis.  All eight farms covered variable costs of producing milk.  Five of the eight farms showed a profit when all costs of production were included. All six farms that raised their own replacement heifers lost money on the enterprise.  With respect to crop production, corn and corn silage were not profitable enterprises.  The hay enterprise was profitable for five of the farms.

Managing Dairy Heifer Growth Investment
Provedor de dados: 31
Autores: Wolf,   Christopher A.; Hadrich,   Joleen C.; Vandehaar,   M.J.
Accelerated prepubertal growth rates can lower heifer raising costs but may put heifers at risk for impaired mammary development and have been found to be detrimental decreased to milk production in the first lactation. The tradeoff between heifer raising costs and milk production loss is examined in a capital budgeting model. Monthly annuity net present value of a heifer investment through the first lactation is assessed for heifers calving at 20, 22, 24, 26 and 28 months of age. A 24 mo AFC base case strategy with 9009.5 kg subsequent first lactation milk yields $7.34 in returns per month. Accelerated growth resulted in higher returns ($12.77/mo for 20 mo AFC; $9.86/mo for 22 mo AFC) when milk production is not affected as total raising costs decline...

ANALYZING REPRODUCTIVE MANAGEMENT STRATEGIES ON DAIRY FARMS
Provedor de dados: 31
Autores: Wolf,   Christopher A.
Milk sales are the largest source of revenue on dairy farms.  Reproduction is necessary to generate a new lactation.  However, a pregnancy also dictates when the previous lactation must end so that the cow can retain sufficient condition into her new lactation.  Pregnancy rate and estrus detection rate determine reproductive success.  From an economics point of view, we talk about calving interval or days open so that a dollar value can be easily associated with the reproductive management program.

CYCLICAL CONCENTRATION AND BIOTECH R&amp;D ACTIVITY: A NEO-SCHUMPETERIAN MODEL

Autores: 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&amp;A activity. This paper develops a formal, dynamic, neo-Schumpeterian model of endogenous R&amp;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&amp;D-activity cycles.

Implications of the Air Compliance Agreement for Livestock Producers
Provedor de dados: 31
Autores: Hadrich,   Joleen C.; Wolf,   Christopher A.
Nutrient management and air emissions continue to be an area of increased management control on all livestock operations as environmental regulations become more stringent. Agricultural producers must consider uncertainty surrounding the timing of and potential increases of environmental policy controls, such as emission taxes, when making future investment decisions. An optimal control theory framework was applied to a dairy farm facing an uncertain increase in emission taxes and an unknown date at which emission taxes will take effect. The optimal investment path considering these uncertainties was solved implicitly and compared to a full certainty case.
