This paper reviews five striking facts about inequality across countries. As Kuznets (1955) famously first documented, inequality first rises and then falls with income. More unequal societies are much less likely to have democracies or governments that respect property rights. Unequal societies...

Advocates of rent control often argue that rent control aids the mixing of rich and poor, and perhaps of the races as well. Economic theory does not necessarily predict that rent control will reduce segregation. The best case for rent control as an aid to integration is that it creates pockets...

Like many other assets, housing prices are quite volatile relative to observable changes in fundamentals. If we are going to understand boom-bust housing cycles, we must incorporate housing supply. In this paper, we present a simple model of housing bubbles that predicts that places with more...

Urban economists understand housing prices with a spatial equilibrium approach that assumes people must be indifferent across locations. Since the spatial no arbitrage condition is inherently imprecise, other economists have turned to different no arbitrage conditions, such as the prediction...

Does America face an affordable housing crisis and, if so, why? This paper argues that in much of America the price of housing is quite close to the marginal, physical costs of new construction. The price of housing is significantly higher than construction costs only in a limited number 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,...

Why are some places more entrepreneurial than others? We use Census Bureau data to study local determinants of manufacturing startups across cities and industries. Demographics have limited explanatory power. Overall levels of local customers and suppliers are only modestly important, but new...

Urban proximity can reduce the costs of shipping goods and speed the flow of ideas. Improvements in communication technology might erode these advantages and allow people and firms to decentralize. However, improvements in transportation and communication technology can also increase the returns...

When members of deliberating groups speak with one another, their predeliberation tendencies often become exacerbated as their views become more extreme. The resulting phenomenon -- group polarization -- has been observed in many settings, and it bears on the actions of juries, administrative...

Why do levels of entrepreneurship differ across America's cities? This paper presents basic facts on two measures of entrepreneurship: the self-employment rate and the number of small firms. Both of these measures are correlated with urban success, suggesting that more entrepreneurial cities are...
