The Effects of Child Physical Maltreatment on Nutritional Outcomes: Evidence from Peru
利用秘鲁0-5岁儿童数据，通过工具变量法处理内生性，发现遭受体罚的儿童短期营养状况显著更差，且更易生病、更少获得医疗保健。
Do children whose parents use physical punishment as a disciplinary method have lower anthropometric measures? Using data for Peruvian children aged 0-5 years, we employ instrumental variables for physical punishment to overcome endogeneity problems common to the household violence literature. Across varying levels of controls, children exposed to physical punishment have significantly poorer short-term nutritional outcomes; although there is no effect on long-term nutrition. We explore heterogeneous effects and potential mechanisms. Children exposed to physical maltreatment fall ill more frequently and are less likely to access preventive and curative healthcare.
