Health knowledge and smoking among South African women
研究了南非女性吸烟选择与健康风险认知的影响因素，使用双变量Probit模型分析不同社会经济群体中无知非吸烟者或无知吸烟者的概率差异。
While several studies of developed countries have attempted to understand individual smoking using economic models, no such studies have been conducted in South Africa. The purpose of this paper is to identify which factors influence individual South African women's choice to smoke cigarettes and their knowledge of the health risks of smoking. To allow for the implied correlation between the unobservable components of the reduced form equations for these health inputs the model is estimated as a bivariate probit. In order to identify those women who are most at risk of becoming smokers and those who are most likely to benefit from health education, the results show how the probability of being an uninformed non-smoker or an uninformed smoker vary across different socio-economic groups.
