Most minimum wage (MW) research focuses on wage and employment impacts in high-income countries. Little is known about broader impacts, including on parental and child health in low- and middle- income countries (LMICs) where most people affected by MWs live. This study studies MW effects on employment, earnings, parental health and child health in Indonesia, the third most-populous LMIC. Results include: MWs improve men’s earnings, parental hemoglobin, and child height-for age and reduce pregnancy complications. This study highlights nuanced but positive roles MWs may play in improving parental and child health, despite not directly affecting women’s earnings and labor supplies.
