A fairly comprehensive range of planting choices made by maize farmers in Kenya (including discrete endogenous variables creating self-selectivity) is modelled and estimated as one system of interrelated decisions. Two-stage and three-stage probit procedures are used to handle the simultaneity...

The Zambian Government encourages crop production in the Gwembe Valley without taking into consideration the risks involved. These risks mainly originate from the stochastic nature of rainfall. This paper, therefore, identifies optimal cropping patterns in the Gwembe Valley by using Target MOT...

This paper develops a stochastic multi-period decision model to analyse a continuous wheat cropping system infested by wild oats (Avena fatua L.), in southern Australia. The multi-period solutions is obtained by employing a dynamic programming model in conjunction with a bioeconomic simulation...

The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water in a single-farm framework. The analysis provides a conceptual and...

Rice is the most important staple food in the People's Republic of China (PRC). In many Asian countries rice appears to have become an inferior good, with income increases leading to declines in per capita consumption as other food products are substituted for rice. In this study, human rice...

Reduced-form price spread models have been recently utilized by Wohlgenant and Mullen, and Thompson and Lyon to evaluate the economic factors affecting the marketing margins for agricultural products. Drawing on Gardner, Heien, Buse and Brandow, Waugh, Tomek and Robinson, and others they specify...

This paper compares three models of input allocation in multicrop systems. In addition to the variable input and satisficing models analyzed in previous research, an allocatable fixed input model of short-run input use is derived. The empirical application studies irrigation water use in the...

Variables related to farmers' awareness and attitudes towards intercropping of immature rubber (Hevea brasiliensis) stands, extension contacts, education level, and experience with farming other crops are positively associated with the probability of adoption. Higher levels of off-farm income...
