For a variety of reasons described in the paper, improving the performance of urban school districts is more difficult today than it was several decades ago. Yet economic and social changes make performance improvement especially important today. Two quite different bodies of research provide...

Will improvements in information technology eliminate face-to- face interactions and make cities obsolete? In this paper, we present a model where individuals make contacts and choose whether to use electronic or face-to-face meetings in their interactions. Cities are modeled as a means of...

What impact does inequality have on metropolitan areas? Crime rates are higher in places with more inequality, and people in unequal cities are more likely to say that they are unhappy. There is also a negative association between local inequality and the growth of both income and population,...

Three quarters of American children have been exposed to neighborhood violence in their lifetimes. Most of the existing research has concluded that exposure to violence leads to restricted emotional development, aggressive behavior and poor school outcomes. However, this literature fails to...

Chinese rural industry has grown three times faster than national GDP, surpassing agriculture in size in 1987, and now nearing half of the total Chinese economy. We use a rich, new county-level data set to explore this dramatic growth. We find that a Cobb-Douglas production function explains...

The standard revealed-preference estimate of a city's quality of life is proportional to that city's cost-of-living relative to its wage-level. Adjusting estimates to account for federal taxes, non-housing costs, and non-labor income produces more plausible quality-of-life estimates than in the...

Urban crime rates in the United States fell markedly during the 1990s and remain at historically low levels. The statistical evidence presented here indicates that that decline, like the crime surge that preceded it, has been largely uncorrelated with changes in socioeconomic conditions across...

Covid-19 is the single largest threat to global public health since the Spanish Influenza pandemic of 1918-20. Was the world better prepared in 2020 than it was in 1918? After a century of public health and basic science research, pandemic response and mortality outcomes should be better than in...

Since the '80s the US has experienced not only a steady increase in income inequality, but also a contemporaneous increase in residential segregation by income. Using US Census data, we first document a positive correlation between inequality and segregation at the MSA level between 1980 and...

We provide measures of ethnic and racial segregation in urban consumption. Using Yelp reviews, we estimate how spatial and social frictions influence restaurant visits within New York City. Transit time plays a first-order role in consumption choices, so consumption segregation partly reflects...
