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...

Our understanding of effects from kindergarten entrance age is complicated by at least two facts: a child's age relative to their classmates may be just as important as their entrance age, and the choice of parents or schools to delay a child's enrollment is likely to be correlated with entrance...

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...

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...
