Abstract: |
The correlation between wage premia and concentrations of firm activity may
arise due to agglomeration economies or workers sorting by unobserved
productivity. A worker's residential location is used as a proxy for their
unobservable productivity attributes in order to test whether estimated work
location wage premia are robust to the inclusion of these controls. Further,
in a locational equilibrium, identical workers must receive equivalent
compensation so that after controlling for residential location (housing
prices) and commutes workers must be paid the same wages and only wage premia
arising from unobserved productivity differences should remain unexplained.
The models in this paper are estimated using a sample of male workers residing
in 33 large metropolitan areas drawn from the 5% Public Use Microdata Sample
(PUMS) from the 2000 U.S. Decennial Census. We find that wages are higher when
an individual works in a location that has more workers or a greater density
of workers. These agglomeration effects are robust to the inclusion of
residential location controls and disappear with the inclusion of commute time
suggesting that the effects are not caused by unobserved differences in worker
productivity. Extended model specifications suggest that wages increase with
the education level of nearby workers and the concentration of workers in an
individual's own industry or occupation. |
