Consumption of Economic Information in Agriculture
构建了一个模型，分析决策者对农业经济信息服务的需求，利用四个商品系统的调查数据，考察人力资本和角色如何影响对不同形式信息的需求。
Abstract We develop a model of decision makers' demand for agricultural economic information services. This modeltreats choice of externaldecision‐support services as a function of actors' assessment of how alternative investments in information complement their internal competencies. Data from a survey in four commodity systems are used to evaluate hypotheses as to how human capital, and functional role of actors in commodity systems affect demand for variously formatted information. By focusing on three axes of heterogeneity—diversity among decision makers, information service providers, and information—we are able to identify key structuraland functional relationships in agricultural economic information systems.
