| Mathematical programming models, as typically formulated for international trade applications, may contain certain implied restrictions limiting price responsiveness, intermediate product flows, and arbitrage possibilities. These restrictions are especially important in the case of dairy, and may lead to results which are technically infeasible, or if feasible, not consistent with market equilibrating behavior. The difficulties encountered when modeling dairy trade are described, and an alternative formulation of a spatial model is presented. This formulation allows joint-inputs, multi-products, intermediate markets, and pure transshipment and product substitution forms of arbitrage. |

| A transshipment model of the Northeast dairy sector is developed to assess the potential for structural change in the manufacturing industry. It is detennined that the reduction of existing hard product processing capacity near metropolitan areas would diminish total costs. Industry-wide savings of about 60 million dollars annually would be realized by fluid, soft product, cheese and butter/powder manufacturers. The model points to finn level as well as industry level incentives to move toward a more concentrated dairy manufacturing sector in the Northeast. |

| A survey of the milk haulers in the Northeast was conducted in June 1992 to assess the status of the industry. Detailed information on characteristics of the hauling businesses as well as the equipment operated was collected. Data submitted by milk haulers with New York addresses was isolated from the survey data set and analyzed on a regional basis. Some of the general topics addressed include the number, size, and location of hauling businesses, wages paid to hired drivers, and the cost of milk hauling equipment. A section is devoted to measures of hauling efficiency. Two sections review the costs involved in milk hauling, the first of which is more general in its approach. The second cost-based section investigates differences in hauling costs between... |

| A survey of the milk haulers in New York and Pennsylvania was conducted to assess the changes in the northeast milk hauling industry since 1981. Detailed information was collected on characteristics of the hauling businesses as well as the equipment operated. Some of the general topics discussed include the number of hauling businesses, the size of hauling businesses, and the cost of milk hauling equipment. To address the subject of hauling efficiency, a section describing common measures of efficiency is included. Where possible, comparisons have been made to statistics obtained from a similar study completed in 1981. |

| After a rapid expansion of the Argentine dairy sector, lower producer prices are expected. As a means of preventing an excessive reduction in dairy farmers’ profitability, an analysis of current profitability and an evaluation of possible improved resource allocation are warranted. This study aims to: 1- establish an optimal plan for dairy farms located in the Santa Fe Sur region, and determine if and how it differs from the current plan; 2- determine if the current resource allocation is efficient in terms of the return-risk tradeoff; 3- evaluate ‘nearly optimal’ plans; and 4- determine the role of herd size in profitability improvement. The comparison of current practices on a representative dairy farm in the Santa Fe Sur region and the optimal solutions... |

| Economists have long considered issues of spatial economic activity, trade, and location values. Among all the various theories presented over the past century, it is safe to say that not one predicts that goods, services, or factors of production must attain the same value at different locations in geographic space. Only under the most extreme conditions, such as zero transportation costs, would it be even conceivable that the same commodity or factor of production be expected to command the same price in two geographically separated markets. With costly transportation, it is possible that two separate markets have nearly the same, or even identical, prices, but there are no theoretically justified reasons to expect such an outcome, a priori. When the... |
