Markets in everything: reverse prostitution edition

Thousands of people in Africa will be paid to avoid unsafe sex, under a groundbreaking World Bank-backed experiment aimed at halting the spread of Aids.

The $1.8m trial – to be launched this year – will counsel 3,000 men and women aged 15-30 in southern rural Tanzania over three years, paying them on condition that periodic laboratory test results prove they have not contracted sexually transmitted infections.

The proposed payments of $45 equate to a quarter of annual income for some participants.

Here is the full story.  It is a joint private sector, public sector initiative, in case you were wondering.  I thank Johannes for the pointer.
