We examine the channels through which a randomized early childhood intervention
in Colombia led to signi cant gains in cognitive and socio-emotional skills among a
sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the
determinants of material and time investments in these children and evaluate the im-
pact of the treatment on such investments. We then estimate the production functions
for cognitive and socio-emotional skills. The e ects of the program can be explained
by increases in parental investments, which have strong e ects on outcomes and are
complementary to both maternal skills and child's baseline skills.
