On the other hand, lower prices may serve as price anchors and, through a comparison effect, decrease subsequent demand. This tension is particularly important for the distribution of health products in low-income countries, where free or heavily subsidized distribution is a common but controversial practice.

In fact, we find that the service led to an increase in promiscuity, and no ...
