Agglomeration and job matching among college graduates
We examine job matching as a potential source of urban agglomeration economies. Focusing on college graduates, we construct two direct measures of job matching based on how well an individual?s job corresponds to his or her college education. Consistent with matching-based theories of urban agglomeration, we find evidence that larger and thicker local labor markets increase both the likelihood and quality of a job match for college graduates. We then assess the extent to which better job matching of college-educated workers increases individual-level wages and thereby contributes to the urban ...

IT and Urban Polarization
We show that differential IT investment across cities has been a key driver of job and wage polarization since the 1980s. Using a novel data set, we establish two stylized facts: IT investment is highest in firms in large and expensive cities, and the decline in routine cognitive occupations is most prevalent in large and expensive cities. To explain these facts, we propose a model mechanism where the substitution of routine workers by IT leads to higher IT adoption in large cities due to a higher cost of living and higher wages. We estimate the spatial equilibrium model to trace out the ...
