| 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. |

| 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... |

| 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. |

| 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. |

| 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. |

| 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... |

| 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... |

| This report summarizes the financial and production records of 141 dairy farms from throughout Michigan. To be included, the farms must have produced at least 50 percent of gross cash farm income from milk and dairy animal sales. The farms in this report were located throughout Michigan. The records came from Michigan State University�s Telfarm/MicroTel project, the Farm Credit Service system, or by AgriSolutions in Michigan. The values were pooled into averages for reporting purposes. The farms are larger than would be the average of all dairy farms in Michigan. Farm records checked for accuracy. While considerable variation in the data exist, average values are reported in the summary tables and discussion that follow. |
