Data from Ecuador's Living Standard and Measurement Surveys were used to analyze the characteristics and determinants of child labor and schooling. Of particular interest was the influence of adult wages on child labor. Survey data on children aged 10-17 included sex, age, rural or urban residence, monthly wages, whether or not attending school, and whether or not working. Family characteristics included educational level and occupational sector of household head and spouse, region of residence, presence of babies or other older children in household, and age and wages of the head of household. Household demographic variables had an impact on the probabilities of children working and of children attending school and had a stronger impact in urban than rural areas. However, in rural areas boys were more likely to work and less likely to attend school than were girls. Parental education had direct and indirect effects on the work and schooling of children. Household head's occupational sector had an impact on both schooling and work. Rural children of household heads working in agriculture were more likely to work than other children. Increasing wages of the household head had a small positive impact on child schooling in rural areas. Implications for public policy are discussed. (Contains 14 statistical tables.) (SV)
