This chapter presents specific questions posed in this research, elements of the conceptual framework, and a synopsis of the sample design. Two levels of observation and analysis are used. At the farm level, the underlying framework is the model of the agricultural household. The economic surplus approach is applied at the industry level. Details of the models are given in each chapter of Part III. The sample villages and households are stratified by elevation and exposure of the surrounding locality to introduction of banana planting material.
