Econometric Analysis of the Short-run Fluctuations of Households' Purchases
提出一种扩展的低频购买模型，利用调查期间家庭购买次数的额外信息，描述随机发生的购买行为，并基于法国家庭食品支出调查数据进行了实证分析。
Infrequency of purchase models are alternatives to those derived from the classical "utility maximization with binding non-negativity constraints" scheme for modelling purchases that occur at random dates. An extension of those models is proposed that takes into account additional information about the exact number of times households purchased during the survey period. Various methods of estimation are described and an empirical illustration is presented with data drawn from the French Food Expenditure Survey (INSEE).
