"What Matters for Choosing Your Neighbors? Evidence From Canadian Metropolitan Areas." (Job Market Paper, with Kristian Behrens). Submitted.
A corollary of the First Law of Geography and the Principle of Homophily is that “near things are more similar than distant things.” We test that proposition using spatially fine-grained data on thousands of ethnic colocation patterns in the six largest Canadian metropolitan areas. These colocation patterns reveal that groups that are more similar along various non-spatial dimensions—language, culture, religion, genetics, and historico-political relationships—colocate more. Our results provide a quantitative glimpse at the ‘deep roots’ of homophily and the role that different characteristics—such as language or religion—play in the ethnic stratification of cities. Our results hold for a wide range of alternative measures and different Census. We also find a heterogenous effect across cities, even an east-west gradient for some variables.

This paper provides new measures that help to overcome the weakness of existing measures of segregation, and allow a researcher to assess its magnitude. We apply point-pattern based measures of geographic concentration—used to assess the spatial clustering of plants—to the measurement of segregation. Our measures of excess segregation satisfy a number of desirable properties, encompass numerous existing approaches to segregation, and succeed in dealing with the problems raised in the literature. It allows us to finely assess the geographic distribution of different groups using spatially fine grained data and offer statistical testing of the observed patterns against various reference distributions, i.e., benchmarks. We show how our measures can be used to partly disentangle segregation by race from the geographic concentration of poverty. Our preliminary results show, for instance, the presence of segregation for black groups compared to a random benchmark. Moreover, after controlling for race, we found that poor black people are even more segregated than black people with higher incomes.

This paper provides a measure for, and empirical application of, the spatial mismatch hypothesis in order to better understand patterns of firms and individuals locations. We first explore how the dynamic of decentralization in the New York area affected different groups in a different magnitude between 1990 and 2010. We then test the spatial physical disconnection between individuals and their potential employers. The article shows a robust empirical regularities of the effect of race and poverty on the spatial mismatch. For instance, we find that White shifted towards jobs while Black, Hispanic and Asian shifted away from total employment. Within each group, the shift between jobs and poor individuals is even more pronounced.
