Occupational Matching and Cities

Endogenous Job Destruction and Job Matching in Cities

We propose a spatial search-matching model where both job creation and job destruction are endogenous. Workers are ex ante identical but not ex post since their job can be hit by a technological shock, which decreases their productivity. They reside in a city and commuting to the job center involves both pecuniary and time costs. Thus, workers with high wages are willing to live closer to jobs ...

RepMatch: Robust Feature Matching and Pose for Reconstructing Modern Cities

A perennial problem in recovering 3-D models from images is repeated structures common in modern cities. The problem can be traced to the feature matcher which needs to match less distinctive features (permitting wide-baselines and avoiding broken sequences), while simultaneously avoiding incorrect matching of ambiguous repeated features. To meet this need, we develop RepMatch, an epipolar guid...

Urban geographers conceptualize the distribution of economic activity across city systems in terms of hierarchy, where functions are related to size, and specialization, where places compete against each other for functional primacy. Using occupational data, we explore the salience of each for U.S. metropolitan areas. We find that large, urbanized places — including “world cities” and “second t...
