BACKGROUND AND OBJECTIVES: Kangaroo mother care (KMC) is a multifaceted intervention for preterm and low birth weight infants and their parents. Short-and mid-term benefits of KMC on survival, neurodevelopment, breastfeeding, and the quality of mother-infant bonding were documented in a randomized controlled trial (RCT) conducted in Colombia from 1993 to 1996. The aim of the present study was to evaluate the persistence of these results in young adulthood.

We study the taxation of sin goods in a two-period, three-good model. Individuals can buy health care to compensate for the damages caused by their earlier sin-good consumption. Individuals are myopic and underestimate the effect of the sinful consumption on health; in their second period, they may acknowledge their mistake or persist in their error. We characterize and compare the first-best and the (linear) second-best taxes in these different settings. In particular, we examine how the results are affected by the way sin-good consumption and health care interact in health production technology.
