Most of this debate has focussed on the application of these models to health care expenditure. This paper revisits the debate in the context of female smoking and drinking, and evaluates the two approaches on three grounds: theoretical, practical and statistical. The two-part model is generally favoured but it is stressed that this comparison should be carried out on a case-by-case basis.214726 bytesapplication/pdfenSelectionTwo-partSmokingDrinkingI12D12C24C25Health--Econometric modelsWomen--Tobacco useWomen--Alcohol useSample selection versus two-part models revisited : the case of female smoking and drinkingWorking Paperhttps://creativecommons.org/licenses/by-nc-sa/1.0/
