Measuring Peer Effects on Youth Smoking Behaviour
用随机效用模型和马尔可夫过程研究美国青少年吸烟中的同伴效应，发现同性别和同种族内同伴影响更强，且存在乘数效应。
This paper examines the role of peer effects in teenagers' smoking behaviour in the U.S.A. I present a random utility model that incorporates complementarity between individual and peer smoking. A Markov process model of smoking interactions between individuals is presented. I estimate the structural parameters of the model using a steady-state distribution that is determined by the Markov process. The empirical results strongly support the presence of positive peer effects. Interestingly, peer interactions are found to be stronger within the same gender than across genders. The same result is found for race. Moreover, a multiplier effect is found. Copyright 2007, Wiley-Blackwell.
