The econometrics literature proposed several new causal machine learning methods (CML) in the past few years. These methods harness the strength of machine learning methods to flexibly model the relationship between the treatment, outcome and confounders, while providing valid inferential...

A new and rapidly growing econometric literature is making advances in the problem of using machine learning (ML) methods for causal inference questions. Yet, the empirical economics literature has not started to fully exploit the strengths of these modern methods. We revisit influential...

We present a theoretical framework which allows for the comparison of the effectiveness of tax measures, loans and funding, in supporting industry-oriented research. We estimate for each of the instruments the exact contribution required by a firm to decide on investing in R&D, given the costs...

This paper explores how a conditional cash transfer program influences students' schooling decisions when program payments stop in the middle of the school career. To that end, I examine Mexico's Progresa, which covered students only until the end of middle school (at age 15) in its early years....

In practice, social and development interventions are often targeted at groups or individuals with the largest expected benefits. In such cases, treatment effects are usually affected by selection on unobservable factors. We show that modeling the process of selective intervention placement...

Public benefit-cost analysis of market policies often relies on a particular definition of market surplus that adds up consumer and producer surplus and external costs. This paper provides an overview of conceptual strategies to deal with moral considerations and then develops an adjusted market...

Policies need not only to be well designed to effectively address market failures, but their parameters also need to be part of agents’ information sets. This is illustrated by government student loans in the Netherlands which are intended to alleviate liquidity constraints. Despite generous...

This paper presents evidence about the impact on school enrollment of a program in Ecuador that gives cash transfers to the 40 percent poorest families. The evaluation design consists of a randomized experiment for families around the first quintile of the poverty index and of a regression...

We apply theories of capital market failure to ana1yzeoptima1 financing of risky higher education. In the market solution,students can only finance their education through debt. There isunderinvestment in human capita1, because some students with socia1lyprofitable investments in human capita1...

Recent studies for primary and secondary education find positive effects of the share of girls in the classroom on achievement of boys and girls. This study examines whether these results can be extrapolated to post-secondary education. We conduct an experiment in which the shares of girls in...
