Defending the Indefensible: Pimps

From the Economist:

...prostitutes do better with pimps—they work fewer hours and are less likely to be arrested by the police or preyed on by gang members. The paper's discussant at the conference, Evelyn Korn of Germany's University of Marburg, said that her favourite result from the study was that pimps pay “efficiency wages”. In other words, pimps pay above the minimum rate required by sex workers in order to attract, retain and motivate the best staff. Mr Levitt said that a few prostitutes asked the researchers to introduce them to pimps.
