Demand for an Undergraduate Education in the Agricultural Sciences
分析1980年代农业与自然资源科学本科入学人数下降的原因，使用两种时间序列模型发现高机会成本是需求停滞的关键因素。
Abstract Undergaduate enrollments in the agricultural and natural resource sciences (AGNR) declined during the 1980s. The present study sought to analyze factors affecting the drop in demand for an AGNR education. Two time‐series pooled models were employed: a household production function (HPF) variant and a Mincerian human capital form. The HPF variant offers the empirical advantage of a price expression that accounts for changes in AGNR demand beyond significant wealth, structural, regional, and gender effects. High opportunity costs of AGNR careers stalled demand during the 1980s—a problem that may persist for some AGNR career areas.
