| In this paper, peculiarities of the process of development of agricultural biotechnological innovations are considered, in particular the distinction between R&D races for gene discoveries and subsequent competition for developing their marketable applications in the form of genetically modified (GM) crops, the results of which determine the payoffs of discovering a gene. A formal two-stage model is specified and analyzed with regard to how different patent protection regimes and other government policies affect firm's R&D strategies and the welfare realized from an innovation. We find that different policy measures affect the outcomes of the two stages of biotechnological innovation differently, which leaves some ambiguity as to which patent... |

| In this paper, we make an attempt to rationalize the strategic behavior of major peanut exporting and importing countries in the framework of imperfectly competitive markets with the focus on the global and inter-American peanut trade. This study is motivated by the fact that liberalizing imperfectly competitive and often distorted markets can have unorthodox effects, in particular increase the incentives to overuse certain trade policies. The results suggest that the South American peanut producers stand to benefit from the reductions in the U.S. peanut production supports but, paradoxically, preservation of a tariff may still be mutually welfare enhancing. In the broader context of global peanut trade, multi-lateral tariff reduction increases the... |

| In the paper, alternative contractual arrangements between crop producers and processors are evaluated with a view of addressing the major issues present in peanut markets in the U.S., the major EU supplier of high quality peanuts. The issues are the thinness of the spot markets and the absence of quality premiums, both of which impair market efficiency. Results indicate that introducing contracts with a system of quality differentials creates incentives for producer self-selection to participate in the post harvest cash market. Moreover, in the presence of sufficiently high common production risk, tournament contracts are more efficient and preferred by the producers than the standard fixed premium schedules. |

| Rainfall Index (RI) insurance provides forage and hay producers with group risk protection against drought related losses. However, insurance premiums and risk protection are currently based on pooled weather data series and do not account for the impacts of specific climate phases, specifically the El Niño Southern Oscillation (ENSO), on local rainfall distribution. This analysis examines differences in the expected payoffs on the RI insurance under varying coverage levels based on probabilities of rainfall shortage during specific climate events at four Agricultural Experiment Stations in Alabama. Policy makers and producers are expected to benefit from the results that show the varying effects of climate on expected payouts from this insurance. |

| The elimination of the marketing quota system that regulated the peanut market since the 1930s has been accompanied by the emergence of marketing contracts between farmers and peanut buyers (mainly peanut shellers). Two types of contracts have been observed, forward contracts for delivery at harvest or at a later date and "option to purchase" contracts. We analyze the clauses of contracts used by major shellers in order to infer the motivation behind these contracts (i.e., risk sharing, reduction of transaction costs, improve coordination, exercise of market power, etc.). The analysis points out that the main role of the contracts is to replace the marketing structure existing prior the 2002 Farm Act, where peanut marketing was quite regulated. In this... |

| The paper presents preliminary results of the analysis of cost efficiency of peanut production in the South-Eastern region utilizing data from the 2001 Peanut Farm Costs and Returns Survey. Stochastic cost frontier analysis using both Cobb-Douglas and translog functional forms is used as the most suitable given data availability and the nature of the industry. Estimation results are used in a discussion of the likely farm-level effects of the 2002 Farm Act, which substituted quota support with marketing assistance loan program. Contrary to our expectations, quota ownership did not significantly affect cost efficiency, which implies that quota ownership is not a discriminating factor in considering the effects of the Farm Act. Other producer... |

| In the paper, we make an attempt to estimate the supply of farmer stock peanuts in the Southeastern Region of the U.S. and evaluate production effects of the recent changes in farm support policies and of trade liberalization that have affected prices. The choice of estimation methodology is dictated by the unavailability of suitable time-series data due to heavily regulated nature of the U.S. peanut markets before 2002. Supply estimation is performed by estimating farm-level supply using cross-sectional survey data on farm-level costs and returns. Results show that producers not able to expand peanut acreage are likely to be vulnerable to price reductions, as there might exist economies of scale. Production on dry land is likely to remain unprofitable at... |

| n the paper, we study price transmission from wholesale peanut prices to retail peanut butter prices. Using monthly data since 1984, we show that, while an increase in peanut prices is almost immediately transferred to peanut butter prices, it takes several months for a price decrease to be reflected in the peanut butter prices. Besides, the long term price transmission effect also appears to be symmetric. The observed short and long-term asymmetry is explained as a result of profit maximizing inventory management and/or some degree of market power in peanut processing. |

| The paper reports results of non-parametric analysis of peanut, corn, and cotton yield distributions by the ElNino Southern Oscillation (ENSO) phases in the Southeastern U.S. For validation purposes, the historical yield data is complemented by a set of simulated peanut yields generated using daily weather data. The hypothesis, justified by the observed South-Eastern climate differences and research on ENSO cycles and planting dates, is that different climate conditions during ENSO cycles translate into different yield distributions and, therefore, insurance premiums (loss to coverage ratios). Kernel density estimates of historical county yield data show consistent patterns in the actuarially fair rate schedules grouped by ENSO phases and geographical... |
