As a source of income, remittances can be spent on consumption and investment. The aim of this study is to quantify the effect of remittances on investment in education: Do remittances increase household education expenditure? To answer this question we apply meta-regression analysis to 1,343 estimates of this effect drawn from 73 studies, covering 30 countries. Our findings confirm the importance of economic resources to educational choices. The incidence of remittances increases education expenditure by about 15% in the average household. When the evidence base is corrected for sample selection, reverse causality, and research design differences, the incidence of international remittances increases education expenditure by about 35% in most countries, by about 53% in Latin America, but remittances have no effect in Eastern Europe and East Asia. Remittances from domestic migration have smaller effects on education expenditure than international remittances. Grouping all estimates relating to females (female headed households, female recipient, and female student), we find no differences in the effect between males and females.
