El impacto de la educación temprana en el mediano plazo

To the best of our knowledge this is the first study to evaluate the medium term impact of early childcare (0-2 years old child). This is carried out by the estimation of efective (actual) marginal returns of early childcare in a non observable heterogeneity context. We estimate the impact on cognitive tests (SIMCE) (Math and Lenguage) taken in the 4th grade of elementary school. Results suggest that early childcare attendance has a nearly zero effect on average population but a negative e¤ect on those who were treated (those who attended all levels of childcare (early, midium, Pre Kinder and Kinder) relative to those non treated (those who attended the latter three levels but not the former). The distribution of the Marginal Treatmente Effect and the estimated parameters of interest suggest that the zero-negative effect would be related to the quality of early childcare.
