Two-Step Econometric Estimation of Farm Characteristics Affecting Marketing Contract Decisions
使用两步计量模型分析农场特征如何影响营销合同的采用、数量、频率和类型，发现影响采用决策的因素与影响后续决策的因素不同。
We examine how farm characteristics affect marketing contract decisions. We relax the restrictive assumptions of Tobit, Poisson, and multinomial logit models and consider the quantity, frequency, and contract type decisions conditional on, rather than jointly with, the contract adoption decision. In contrast to earlier studies on marketing contract decisions, we estimate a two-step econometric model using Agricultural Resource Management Study data and find that farm characteristics affecting decisions to adopt marketing contracts differ from those affecting decisions regarding quantity, frequency, and contract type.
