We study the impact of natural resource royalties on educational outcomes in Colombia. We analyze a reform enacted in 2012 that made the distribution of these royalties more equitable. Before the reform, most royalties were assigned to the regions where the natural resources were exploited; with...

This study examines the effect of quality of electrification on empowerment of women in terms of economic autonomy, agency, mobility, decision-making abilities, and time allocation in fuel collection in India. It moves beyond the consensus of counting electrified households as a measure of...

The public mechanical clock and the movable type printing press were two of the most important and complex general purpose technologies of the late medieval period. We document two of their most important, yet unforeseeable, consequences. First, an instrumental variables analysis indicates that...

This paper analyzes the identifying power of weak convexity assumptions in treatment effect models with endogenous selection. The counterfactual distributions are constrained either in terms of the response function, or conditional on the realized treatment, and sharp bounds on the potential...

This paper explores semi-monotonicity constraints in the distribution of potential outcomes, first, conditional on an instrument, and second, in terms of the response function. The imposed assumptions are strictly weaker than traditional instrumental variables assumptions and can be gainfully...

The credibility of standard instrumental variables assumptions is often under dispute. This paper imposes weak monotonicity in order to gain information on counterfactual outcomes, but avoids independence or exclusion restrictions. The outcome process is assumed to be sequentially ordered,...
