dc.description.abstract	Estimates of participation or expenditure elasticities depend upon the assumptions made regarding the observation of zero expenditure at the household level. This research examines two single-hurdle models across two commodities for which nearly two-thirds of the observations are zero. The research shows that one hurdle model consistently outperforms the other, and does so for intuitively appealing reasons.	en
