Double-hurdle and purchase-infrequency demand analysis: a feasible integrated approach
提出一个整合模型，将双重障碍模型和购买频率模型作为特例，蒙特卡洛模拟表明该模型对审查规则的误设更稳健，并应用于以色列烟草产品需求分析。
This paper proposes an integrated model that incorporates, as special cases, the double-hurdle and the purchase-infrequency models, both previously used to account for zero observations in commodity demand analyses. Monte-Carlo simulations show that the integrated model is more robust to misspecification of the censoring rule than any of the two simpler models. The integrated model is then applied to the demand for tobacco products in Israel. The purchase-infrequency results were closer to those of the integrated model than the results of the double-hurdle model.
