This article examines the emergence and benefits of contract farming in East Java, Bali, and Lombok, Indonesia. After a general review of contract farming in these regions, three contracts, for seed corn in East Java, seed rice in Bali, and broilers in Lombok are described and analyzed using key informant interviews and household survey data. A review of the contracts suggest that there is a wide array of contract types and this is related to the technical requirements of production and the associated costs. Probit analysis is used to identify factors contributing to smallholder participation in farm contracts and a two-stage estimation process used to measure the effects of farm contracts on gross margins and labor use. Results indicate participation in contracts is influenced by farm size and other factors such as smallholder's age, education, and participation in farm groups. Contracts increased returns to capital for the seed corn and broiler contracts but not for the seed rice contract. All three contracts influenced the types of labor used; however, none of them influenced total farm employment. Copyright 2005 International Association of Agricultural Economics.
This article evaluates a hybrid seed contract between Indonesian smallholders and Pioneer Hybrid International. A transaction cost approach was used to analyse contract participation, total farm gross margins and labour and chemical use. The empirical results suggest: (a) the contract favours farmers with more irrigated land; (b) the contract improved returns to farm capital and was welfare improving; (c) the contract increased the demand for non-family labour, particularly female labour; and (d) the contract increased the intensity of chemical use. The success of the contract was attributed to the nature of the contracting process, which was between Pioneer and grower groups and not individual smallholders.
In the present study, we used functional MRI in awake rats to investigate the pain response that accompanies intradermal injection of capsaicin into the hindpaw. To this end, we used BOLD imaging together with a 3D segmented, annotated rat atlas and computational analysis to identify the integrated neural circuits involved in capsaicin-induced pain. The specificity of the pain response to capsaicin was tested in a transgenic model that contains a biallelic deletion of the gene encoding for the transient receptor potential cation channel subfamily V member 1 (TRPV1). Capsaicin is an exogenous ligand for the TRPV1 receptor, and in wild-type rats, activated the putative pain neural circuit. In addition, capsaicin-treated wild-type rats exhibited activation in brain regions comprising the Papez circuit and habenular system, systems that play important roles in the integration of emotional information, and learning and memory of aversive information, respectively. As expected, capsaicin administration to TRPV1-KO rats failed to elicit the robust BOLD activation pattern observed in wild-type controls. However, the intradermal injection of formalin elicited a significant activation of the putative pain pathway as represented by such areas as the anterior cingulate, somatosensory cortex, parabrachial nucleus, and periaqueductal gray. Notably, comparison of neural responses to capsaicin in wild-type vs. knock-out rats uncovered evidence that capsaicin may function in an antinociceptive capacity independent of TRPV1 signaling. Our data suggest that neuroimaging of pain in awake, conscious animals has the potential to inform the neurobiological basis of full and integrated perceptions of pain.
A farm financial model with leverage and investment in two farm enterprises is specified. The model is extended to incorporate futures hedging and the Separation Theorem is used to show that optimal hedging is zero. The assumption of a risk‐free asset is relaxed and, while this leads to a violation of the Separation Theorem, the result that optimal hedging is zero is maintained providing that futures markets are efficient. It is concluded that if capital markets are efficient then farmers will have little interest in futures markets except to speculate.
A farm portfolio model is speci¢ed with two risky enterprises and a risk-free asset which may be held short or long by the farmer. The model is solved numerically using a genetic algorithm. It is shown that the assumption of competitive adaptation leads to a violation of normative e¤ciency. Those who survive are not the most e¤cient in a normative sense.
