Evidence against Imposing Restrictions on Hurdle Models as a Test for Simultaneous versus Sequential Decision Making
论证了不能通过障碍模型的限制条件来检验决策是同时发生还是序贯发生，并发现未能拒绝这些限制与样本量负相关，证据来自自然数据和模拟数据。
Abstract Agricultural economists frequently employ hurdle models to estimate the determinants of truncated outcomes such as market participation and adoption. A pervasive belief is that restrictions can be placed on hurdle models to test whether the decisions made in the underlying data‐generating process occurred sequentially or simultaneously. This article argues against the ability to draw this conclusion and further submits there is a negative correlation between failing to reject these restrictions and sample size. Evidence to support both proposals comes from data collected in a natural setting, as well as simulated data with a known data‐generating mechanism.
