Abstract:
A fundamental puzzle about human behavior is low investment in preventive health inputs. Present-biased preferences have frequently been put forth as a theoretical explanation for this, but with limited empirical evidence supporting it, especially in developing countries. We extend our previous analysis of a field experiment testing advertising strategies to increase demand for a potentially life-saving preventive health technology, voluntary medical male circumcision. Offering compensation of US$10 conditional on a complement to the procedure, a short counseling session at a providing clinic, tripled uptake of the procedure. This is consistent with the idea that subsidizing a complement encouraged procrastinating men with latent demand to invest in preventive health. In addition, framing the basic advertisement using the statement "Are you tough enough?" doubled uptake.
