The long shadow of the Iron Curtain for female sex workers in German cities: Border effects and regional differences
研究了德国性工作的习惯和价格决定因素，发现前东德地区（尤其是柏林等大城市）的性服务价格高于西德，且存在区域内的习惯形成和溢出效应。
This paper assesses determinants of habits and prices about sexual work in Germany. The paper alludes to a regional pattern, in particular, in pricing. This pattern varies with the size of cities and across as well as along the former East–West German border. In particular, the evidence suggests that there is a long shadow of the former Iron Curtain which leads to higher conditional prices in the former East than in the West, in particular, in larger agglomerations such as Berlin. Moreover, there is evidence of habit formation and spillovers within regions, which leads to regionally clustered prices as well as unsafe sex services being offered by sexworkers.
