This paper examines the effects of birth order on the child labor incidence and school attendance of Brazilian children. Evidence from the psychology and sociology literature suggests that earlier-born children tend to have higher innate abilities. The economic implications of these findings are that earlier-born children may have more intra -household(More)
BACKGROUND Anatomic segmentectomy has been proposed as a reasonable alternative to lobectomy in the management of small early-stage non-small cell lung cancers. We reviewed our outcomes with anatomic segmentectomy versus lobectomy for stages IA and IB non-small cell lung cancer stratified by age and stage. METHODS We conducted a retrospective review of(More)
This paper presents new evidence of the causal effect of family size on child quality in a developing-country context. We estimate the impact of family size on child labor and educational outcomes among Brazilian children and young adults by exploring the exogenous variation of family size driven by the presence of twins in the family. Using the Brazilian(More)
This paper explores the question: is working as a child harmful to an individual in terms of adult outcomes in earnings? Although this is an extremely important question, little is known about the effect of child labor on adult outcomes. Estimations of an instrumental variables earnings model on data from Brazil show that child labor has a large negative(More)
Health and the Evolution of Welfare across Brazilian Municipalities This paper describes the pattern of reductions in mortality across Brazilian municipalities between 1970 and 2000, and analyzes its causes and consequences. It shows that, as in the international context, the relationship between income and life expectancy has shifted consistently in the(More)
An extensive survey data set of Brazilian households is used to test whether intrahousehold gender bias affects the decisions of mothers and fathers to send their sons and daughters to work and to school. An intrahousehold allocation model is examined in which fathers and mothers may affect the education investment and the child labor participation of their(More)
This paper we examine intra-household gender differences and the incidence of child labor and children’s school attendance in Brazil to test whether the unitary model of household allocations is suitable in the child labor context. We begin by building an intra-household allocation model where fathers and mothers may affect the education investment and the(More)
Child Labor and Learning This paper investigates the impact of working while in school on learning outcomes through the use of a unique micro panel dataset of students in the São Paulo municipal school system. The potential endogeneity of working decisions and learning outcomes is addressed through the use of a difference-in-difference estimator and it is(More)
This work investigates the Movement Imagination training using Principal Component Analysis (PCA) and Magnitude-Squared Coherence (MSC) as features extractor. The characteristics were extracted by using the Delta band (0.1-2 Hz), Alpha band (8-13 Hz) and Beta band (14-30 Hz) and the classifier was Multilayer Perceptron (MLP). Thus., the electroencephalogram(More)
