Smoke and strong whiskey : factors influencing female smoking and drinking in Ireland

This paper analyses decisions regarding smoking and drinking for a sample of Irish women. 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.
