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 efficiency gains over the status quo aid...

This paper presents a generalization of the DeGroot learning rule in which social learning can lead to polarization, even for connected networks. I first develop a model of biased assimilation in which the utility an agent receives from past decisions depends on current beliefs when uncertainty...

This paper performs a subgroup analysis on the effect of receiving a Moving to Opportunity (MTO) housing voucher on test scores. I find evidence of heterogeneity by number of children in the household in Boston, gender in Chicago, and race/ethnicity in Los Angeles. To study the mechanisms...

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...

This paper estimates neighborhood effects on adult labor market outcomes using the Moving to Opportunity (MTO) housing mobility experiment. We propose and implement a new strategy for identifying transition-specific effects that exploits identification of the unobserved component of a...

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 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...

This paper evaluates a new technology for providing water. The technology, developed by Haiti Outreach (HO), is distinguished by a program training communities to manage wells. The effects of training are identified by comparing HO's wells with wells refurbished by HO but subsequently managed...

Landlords in high-opportunity neighborhoods screen out tenants using vouchers. In our correspondence experiment, signaling voucher status cuts landlord responses in half. This voucher penalty increases with posted rent and varies little with signals of tenant quality and race. We repeat the...
