| Human papillomavirus (HPV) infection is the most common sexually transmitted disease in the world and is related to the etiology of cervical cancer. The most common high-risk HPV types are 16 and 18; however, the second most prevalent type in the Midwestern region of Brazil is HPV-33. New vaccine strategies against HPV have shown that virus-like particles (VLP) of the major capsid protein (L1) induce efficient production of antibodies, which confer protection against the same viral type. The methylotrophic yeast Pichia pastoris is an efficient and inexpensive expression system for the production of high levels of heterologous proteins stably using a wild-type gene in combination with an integrative vector. It was recently demonstrated that P. pastoris can... |

| We examine determinants of the nearly 30 percent increase in the average age of domestically produced, registered automobiles since the mid-1960s. We find that very little of the increase in car longevity is attributable to improvements in the inherent durability of cars. Rather, we find that the temporal pattern of longevity improvement is highly correlated with the level of market concentration in the auto industry. In particular, we argue that the arrival of competition in the industry led to an increase in longevity largely by forcing a reduction in the price of auto maintenance and repair, which in turn induced consumers to maintain their cars into older age. |

| 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. |

| The purpose of the research is to improve our understanding of the adaptation process in agriculture at the farm level and the influence through the value chain. The research identified critical managerial decision areas in the strategic planning process of blackcurrant growers in Alberta and the South Island of New Zealand. The work was a comparative study of growers that attempted to determine the correspondence between the results of case study observations and a set of theoretical propositions that were developed from a review of the relevant literature. Results indicate that growers understand their own firm’s core competencies, plan strategically and contingently to maintain flexibility and retain niche advantages. Data gathered on the blackcurrant... |

| This study addresses the issues of market integration in railroad industry analyzing the export-bound grain transportation. A spatial analysis involving four origin states (Illinois, Iowa, Minnesota and Nebraska) and two destinations (Mexican Gulf and Pacific Northwest) is conducted in order to determine if pricing practices by the same or different railroads in different regions are consistent. A system of structural equations is estimated and dynamic regression tests are conducted because of the dynamic nature of interregional trade and arbitrage activities. The results indicate that grain transportation market by rail is not perfectly integrated. This is primarily due to numerous mergers and combining of railroads that took place during the last twenty... |

| The purpose of this research report is to identify the appropriate market benchmark price to use to evaluate the pricing performance of market advisory services that are included in the annual AgMAS pricing performance evaluations. Five desirable properties of market benchmark prices are identified. Three potential specifications of the market benchmark price are considered: the average price received by Illinois farmers, the harvest cash price, and the average cash price over a two-year crop marketing window. The average cash price meets all of the desired properties, except that it would not be easily implementable by producers. It can be shown, though, that the price realized via a more manageable strategy of "spreading" sales during the marketing... |

| Predominance of production and marketing contracts in the broiler industry suggests a traditional analysis of price relationships might no longer be appropriate. In this study, markets for broiler cuts are defined as spatial. Results of a vector autoregressive regression analysis of monthly USDA data from 1987 to 2000 verify the price relationship between white meat and whole broiler prices. Price shocks in the boneless skinless breast market have a greater effect than dark meat shocks, suggesting this market is most important in price transmission. These results will assist industry participants to form more effective marketing and pricing strategies, thus adding efficiency to the market. |

| The objective of this paper is to describe different types of value chain, to capture value added activities of each chain, to discuss the organizational and institutional link in each value chain and its implications for the role of small farmers. We focus on two counties in Hebei and Zhejiang of China. Taking pear for example, analysis of value chain is conducted using data of representative samples of pear value chain. For each chain, value added activities, cost composition, profit distribution, organizational and institutional linkages are illustrated, and corresponding conclusions are indicated. After a systematic analysis of organizational and institutional linkage and value adding activities of every chain as well as cost-benefit analysis of... |

| Following recent telecommunications mergers, local (mostly municipal and county) governments and the federal government are fighting over who should determine whether cable television systems must make their facilities available to unaffiliated providers of high-speed ("broadband") Internet service. This intergovernmental dispute is only the latest in a series of such clashes regarding competition and communications policy. A brief review of the policy suggests that substantively, local open-access requirements are not yet warranted. However, the economics of federalism, primarily that the relevant markets are local, indicates that local governments should have the right to choose these policies, perhaps erroneously. Federal preemption could prevent... |
