Double-hurdle models are estimated to determine whether decisions to smoke/drink are made independently of how much to smoke/drink. Given the potential complementarities between smoking and drinking a model which allows for the joint determination of smoking and drinking is also estimated. The paper finds that decisions to smoke/drink and how much to smoke/drink are not independent and that decisions to smoke/drink are not made independently of each other.179816 bytesapplication/pdfenSmokingDrinkingDouble-hurdleSelectionI12D12C24C25Women--Tobacco useWomen--Alcohol useDecision making--Mathematical modelsWorking Paperhttps://creativecommons.org/licenses/by-nc-sa/1.0/
