The effect of a land titling programme on households’ access to credit

This paper assesses the effects of property titling on households’ access to and use of credit by focusing on household responses to an exogenous change in their formal ownership status. We isolate the credit effect on legal ownership by comparing households from communities in Osasco, Brazil. Our statistical estimates suggest that land titling increases credit use, decreases reliance on credit borrowed from relatives, and increases credit borrowed from commercial banks. We also find that treated households increased their consumption of time-saving durable goods, which explains an observed reallocation of time among household members, with adults working more and children less.

Impact evaluation helps deliver development projects

Does research add value to aid? Specifically, does impact evaluation research help or hinder the delivery of development projects? This paper analyzes the question by constructing a new data set of 100 impact evaluations and 1,135 projects approved by the World Bank between 2005 and 2011. The analysis finds that the delivery of projects with impact evaluation is significantly timelier: common delays are avoided and the gap between planned and actual disbursements is reduced by half. Evidence-based mid-course corrections, a clearer implementation road map, strengthened capacity on the ground, and observer effects are possible channels to explain the results. Hopefully, this analysis will stimulate discussion over the optimal balance between project financing and the impact evaluation research needed to deliver development outcomes.

The Distributive Effects of Land Titleon Labor Supply : Evidence From Brazil

This paper studies the effects of property-titling on labor supply. The role of legal ownership security is isolated by comparing the effect that being part of, or excluded from, a land title program in a unique quasi-experiment in two similar communities in the Brazilian city of Osasco. Our main innovation is the estimation of the distributive impact of land title on hours worked via the quantile regression methodology and the weighting estimator of Firpo (2007). The estimates suggest that the impact of land-titling on labor supply is heterogeneous and greater for those households with fewer hours worked before the program.

Short- and Long-Term Effects of a Child-Labor Ban

This is the first study to investigate the short- and long-term causal effects of a child-labor ban. The study explores the law that increased the minimum employment age from 14 to 16 in Brazil in 1998, and uncovers its impact on time allocated to schooling and work in the short term and on school attainment and labor market outcomes in the long term. The analysis uses cross-sectional data from 1998 to 2014, and applies a fuzzy regression discontinuity design to estimate the impact of the ban at different points of individuals’ lifecycles. The estimates show that the ban reduced the incidence of boys in paid work activities by 4 percentage points or 27 percent. The study finds that the fall in child labor is mostly explained by the change in the proportions of boys working for pay and studying, and observes an increase in the proportion of boys only studying as a consequence. The results suggest that the ban reduced boys’ participation in the labor force. The study follows the same cohort affected by the ban over the years, and finds that the short-term effects persisted until 2003 when the boys turned 18. The study pooled data from 2007 to 2014 to check whether the ban affected individuals’ stock of human capital and labor market outcomes. The estimates suggest that the ban did not have long-term effects for the whole cohort, but found some indication that it did negatively affect the log earnings of individuals at the lower tail of the earnings distribution.
