Interpreting the rational addiction model
回顾了Becker和Murphy的理性成瘾模型在理论上的争议，并指出应用该模型时需谨慎的领域，对研究成瘾行为的经济学者有参考价值。
The rational addiction (RA) model of Becker and Murphy (Becker GS, Murphy KM. A theory of rational addiction. J Pol Econ 1988; 96(4): 675-700) has rapidly become one of the standard models in the literature on addictive behaviour. This paper reviews some theoretical issues surrounding its use, and indicates areas in which caution should be used in applying this model.
