Many social commentators have raised concerns over the possibility that increased sorting in a society can lead to greater inequality. To investigate this we construct a dynamic model of intergenerational education acquisition, fertility, and marital sorting and parameterize the steady state to...

Why do low-income individuals often oppose redistribution? We hypothesize that an aversion to being in "last place" undercuts support for redistribution, with low-income individuals punishing those slightly below themselves to keep someone "beneath" them. In laboratory experiments, we find...

Existing theoretical models of intergenerational transmission of socioeconomic status have strong implications for the association of outcomes across multiple generations of a family. These models, however, are highly stylized and do not encompass many plausible avenues for transmission across...

We examine how economic stratification affects inequality and growth over time. We study economies where heterogenous agents interact through local public goods or externalities (school funding, neighborhood effects) and economy-wide linkages (complementary skills. knowledge spillovers). We...

The high degree of variance of crime rates across space (and across time) is one of the oldest puzzles in the social sciences (see Quetelet (1835)). Our empirical work strongly suggests that this variance is not the result of observed or unobserved geographic attributes. This paper presents a...

Social commentators from William Julius Wilson to Charles Murray have argued that increased sorting of people into internally homogeneous" neighborhoods,schools, and marriages is spurring long-run inequality. Cali- bration of a formal model suggests that these fears are misplaced. In order to...

We study how class size and class composition affect the academic and labor market performance of college students, two crucial policy questions given the secular increase in college enrollment. Our identification strategy relies on the random assignment of students to teaching classes. We find...

Tiebout's classic 1956 paper has strong implications regarding stratification across and within jurisdictions, predicting in the simplest instance a hierarchy of internally homogeneous communities ordered by income. Typically, urban areas are less than fully stratified, and the question arises...

In Beijing, the metropolitan government has made enormous place based investments to increase green space and to improve public transit. We examine the gentrification consequences of such public investments. Using unique geocoded real estate and restaurant data, we document that the construction...
