War, Migration and the Origins of the Thai Sex Industry
研究美国越战军事存在如何通过需求冲击和女性移民供给弹性，塑造了泰国性产业的空间分布，并关联了1990年代初的HIV爆发。
This paper analyzes the determinants behind the spatial distribution of the sex industry in Thailand. We relate the development of the sex industry to an early temporary demand shock, that is, US military presence during the Vietnam War. Comparing the surroundings of Thai military bases used by the US army to districts close to unused Thai bases, we find that there are currently five times more commercial sex workers in districts near former US bases. The development of the sex industry is also explained by a high price elasticity of supply due to female migration from regions affected by an agricultural crisis. Finally, we study a consequence induced by the large numbers of sex workers in few red-light districts: the HIV outbreak in the early 1990s.
