| We present a theoretical framework for understanding the relationship between anchoring bias, hypothetical bias, and cheap talk in constructed markets. In our theory, interviewers provide agents with signals such as cheap talk and bid values while eliciting the value for nonmarket goods. In response to these signals, agents revise their prior distributions over the value of the good. Previous empirical studies have failed to account for the interaction between cheap talk and anchoring during this updating process, leading researchers to incorrectly assess the effects of cheap talk in reducing hypothetical bias. In particular, we predict that cheap talk will appear to be more effective for relatively large bids. We test our theory in an experimental... |

| We develop a Bayesian implementation of the standard optimal hedging model to analyze the impact of hedgers' subjective views on their hedging behavior. The results show the subjective views have a substantial impact on hedgers' optimal positions, explaining the large cross-sectional and time series variation of hedging positions in practice. |

| Since its first detection in the North Central region in July 2000, the soybean aphid (Aphis glycines Matsamura) has caused considerable loss in soybean (Glycine max L.) yield, bean quality, and producer income. Discovered first in Wisconsin and then in adjoining states, it is currently distributed in 21 US states and parts of Canada. In 2003, over 42 million acres of soybean in the North Central US were infested and over 7 million acres were treated with insecticides to control soybean aphid (Landis et al. 2003). Populations exceeding 24,000 aphids per plant and 40% losses in seed yield have been reported (DiFonzo & Hines 2002). Even prior to the outbreak of 2003, the Soybean Strategic Pest Management Plan identified soybean aphid as one of the key... |

| A transferência de embriões (TE) já vem sendo utilizada em eqüinos há pelo menos duas décadas, sempre a partir de ovulação simples. Para aumentar a eficiência reprodutiva, este estudo avaliou a bipartição embrionária como uma alternativa para melhorar os índices de gestação na transferência de embriões em eqüinos. Foram utilizadas 21 éguas de diferentes padrões raciais, com idade variando entre 4 e 15 anos de idade, pesando entre 270 a 480kg. A partir da identificação do cio (rufiação), os animais foram monitorados através de exames ultra-sonográficos trans-retais até o momento da ovulação, sendo as receptoras, uma vez ao dia e as doadoras três vezes ao dia. As receptoras utilizadas ovularam um dia antes ou até três dias depois das doadoras. As doadoras... |

| This publication began as a need for a short summary of farm programs and farm bills for two agricultural economics courses focusing on agricultural policy -- ag. economics 429, and ag. economics 614. Over time, it became clear that many students taking these courses had less and less background in agriculture and less (even cursory) knowledge of policies than those of the recent past. After this list was developed, a number of other professional agricultural economists found copies and began to use it, hence its publication in a more structured form. The list of Farm Program Provisions is not all-inclusive. It certainly does not contain all the laws and provisions that have affected agriculture over the years. However, it is an easy reference to farm... |

| This paper presents an evaluation of a farm-business assessment model that uses financial performance measures and tracks ‘wealth change’ to evaluate performance trends over time, and ranks the relative business performance of commercial participants. Its core component involves the use of comparative analysis, which is structured as an introductory rapid-assessment model, together with a ranking system that has been designed to differentiate the relative performance levels of farm businesses. The system has been labelled as the Business Performance Index (BPI) model to reflect its performance-ranking role that explores the relationships, if any, between farmer attitudes and business performance. The BPI model is discussed within the context of the debate... |

| In China, with the cost of improved technology rising, surplus labor shrinking, and demand for food quality and safety increasing, it will be just a matter of time before the country's hog production sector will be commercialized like that of developed countries. However, even if China's cost of production converges to international levels, as shown in this case study, China may continue to retain some competitive advantage because of the labor-intensive nature of the marketing services involved in hog processing and meat distribution. The supply of variety meats offers the most promising market opportunity for foreign suppliers in China. The market may open further if the tariff rate for variety meats is reduced from 20% and harmonized with the pork... |
