Red Light States: Who Buys Online Adult Entertainment?
The fifth column shows that subscriptions are more prevalent in regions with higher measures of social capital. Following the Social Capital Index developed in Putnam (2000), I obtain DDB Life Style Survey data from 1991 to 1998 on
consumers in 340 metropolitan areas, and I form a social capital index based on
prevalence of people donating blood, engaging in volunteer activities, or participating in community projects. In a region where 1 percent more people participate in these activities, subscriptions to the adult entertainment service are 0.09 percent more widespread.
