In the U.S., the debate around the minimum wage does not lack controversy, but it does lack up-to-date research. Academic studies on the effects of raising hourly pay—especially to $15, which has become something of a magic number for progressive cities and states—have not kept pace with the whirlwind movement. And relatively little research has focused on the non-economic impacts of such significant wage bumps: for example, how they affect the health of infants.

This is no arbitrary question. Women make up the majority of minimum-wage workers. In the U.S., income level has a pronounced, positive link to birth weight and infant mortality. Low birth weights are associated with myriad long-term poor outcomes for children, including respiratory and cardiovascular sickness, cognitive and developmental issues, and lower educational attainment. These effects have led some economists to characterize the health trajectories for some kids born to poor parents as being “unequal at birth.”
