This paper quantitatively compares water infrastructure interventions that prioritize equity with those that prioritize efficiency. The community-based model developed by Haiti Outreach (HO) trains communities to operate and maintain wells, and has clear effi ciency gains over the status quo aid...

Structural Causal Models define causal effects in terms of a single Data Generating Process (DGP), and the Rubin Causal Model defines causal effects in terms of a model that can represent counterfactuals from many DGPs. Under these different definitions, notationally similar causal effects make...

The Moving to Opportunity (MTO) experiment randomly assigned housing vouchers that could be used in low-poverty neighborhoods. Consistent with the literature, I find that receiving an MTO voucher had no effect on outcomes like earnings, employment, and test scores. However, after studying the...

The international community has pledged $11 billion to Haiti, a country where nongovernmental organizations (NGOs) provide nearly all public goods and services. This raises at least two questions: How can NGOs most effectively perform their own work, and how can NGOs integrate their programs...

Kindergarten-entrance-age effects are difficult to identify due to the nonrandom allocation of entrance-age and simultaneous relative-age effects. This paper presents evidence that instrumental variable frameworks do not identify age effects for the youngest children of a cohort using the...

This paper presents a new perspective on results from the Moving to Opportunity (MTO) housing mobility program. Building on recent developments in the program evaluation literature, this paper defines several treatment effect parameters and then estimates and interprets these parameters using...

The interpretation of estimates from Moving to Opportunity (MTO) as neighborhood effects has created significant controversy among social scientists. This paper presents a framework that clarifies the interpretation of results from the MTO housing mobility experiment. The paper defines several...

A wide literature uses date of birth as an instrument to study the causal effects of educational attainment. This paper shows how parents delaying their children’s initial enrollment in kindergarten, a practice known as redshirting, can make estimates obtained through this identification...

This paper estimates Local Average Treatment Effects (LATEs) of neighborhood quality from the Moving to Opportunity (MTO) housing mobility experiment in a generalized model with multiple treatment levels. We propose a new approach to identifying parameters that exploits the identification of...

Trying to learn about neighborhood effects from the Moving to Opportunity (MTO) housing mobility experiment by focusing on its program effects obfuscates the evidence on neighborhood effects from MTO. This paper shows that using Intent-to-Treat (ITT) and Treatment-on-the-Treated (TOT) program...
