好在Becker之后有很多人做了理论研究,有人在七十年代出版了《妓女经济学》,02年在JPE上有一个Clombia的教授发表了一篇《The theory of prostitution》,他得出的结论比我还要极端,他说"wives and whores are substitute",这篇文章我怎么也找不到,不过我觉得他的结论是有问题的,至少没有把我的三个要素都考虑进去,至少只能说是部分替代。
A Theory of Prostitution Lena Edlund and Evelyn Korn February 16, 2001 Abstract Prostitution is a profession that is low-skill, labor intensive, female, and well paid. This paper proposes the following explanation. A woman can be either wife or prostitute, but not both. If marriage is a source of income for women, then the prostitute has to be compensated for foregone marriage market opportunities. Hence, prostitution must be better remunerated than other low-skill occupations. Furthermore, we discuss the link between income and prostitution, and show that prostitution may decrease not only in female income but also in male income, suggesting one reason why prostitution has seen a secular decline in developed countries. We point to the role of male sex ratios, and males in transit, in sustaining high levels of prostitution, and discuss possible reasons for its low reputation. Finally, we argue that recognition of prostitution as a female strategy may add to the understanding of the evolution of marriage patterns.
