| This paper employs multivariate regression to forecast the calorie intake of Bangladeshi farm households in the hunger season based on the household income, production, and demographic composition in the current (post harvest) season. Nutritional vulnerability profiles are derived from the estimation of ex ante mean and variance of future consumption. The results show the income increase induced by introducing transgenic rice will reduce each individual household's probability of suffering a future consumption shortfall and its vulnerability. The overall vulnerability profile of farm households improves in Bangladesh. |

| In this paper we consider factors that affect both crop prices and yields in order to examine supply responses of major crops in the Southeast. Due to the variable nature of crop production in the Southeast, previous studies that ignore price and yield risk may fail to capture one of the salient features of the region’s agriculture. Our results indicate supply elasticity values for corn, cotton, and soybeans of approximately 0.670, 0.506, and 0.195, respectively. Compared with the results of studies in other regions, corn and cotton acres respond more to price changes and soybean acres respond less to price changes. |

| The spread of agricultural biotechnology in developing countries has grown rapidly in recent years. Several transgenic products are under development with potential to address a variety of adverse production conditions. These products have raised hope that yield and quality improvements in rice will accelerate and help in the battle against under-nutrition, especially in areas of prevalent under-nutrition in Asia. A farm household model is developed and estimated to project ex ante effects of introducing transgenic rice on farm households¡¯ nutritional status in Bangladesh. Assuming the yield effects of transgenic rice are similar to that of previous high yield varieties, the model estimates the profit effect of introducing transgenic rice. The profit... |
