Task Specialization in U.S. Cities from 1880-2000∗

چکیده
We introduce a new methodology for measuring the production tasks undertaken within occupations. We use this methodology to provide the first evidence on the evolution of production tasks in urban and rural areas in the United States from 1880-2000. We find that tasks involving thought, communication and intersocial activity (“interactiveness”) were more concentrated in densely-populated areas in 2000, but not in 1880. We provide evidence in support of the predictions of a model of agglomeration and the task composition of employment, in which reductions in trade costs lead to an increased concentration of interactive tasks in metro areas.

U . S . Cities , 1880 - 1930
We investigate the role of industrial structure in labor productivity growth in U.S. cities between 1880 and 1930 using a new dataset constructed from the Census of Manufactures. We find that increases in specialization were associated with faster productivity growth but that diversity only had positive effects on productivity performance in large cities. We interpret our results as providing s...
متن کاملWeb Appendix for Task Specialization in U.S. Cities from 1880-2000: Not for Publication
In this section, we outline a theoretical model that we use to rationalize the empirical results reported below. First, the model explains a secular reallocation of employment over time towards more interactive occupations in terms of differences in productivity growth across occupations and inelastic demand. Second, the model predicts that this reallocation is stronger in metro areas than in n...
متن کاملEconomic Trends in the Desert Southwest
trong economic interaction exists between communities on both sides of the U.S.–Mexico border. Just count the number of Mexican license plates on autos parked in U.S. malls, or note the many service and goods suppliers in U.S. border cities that support manufacturing in Mexico. Casual observation reveals patterns of local specialization, where work is often divided between the two cities on a s...
متن کاملCities as Hierarchists or Specialists? Evidence from Occupational Profiles
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...
متن کاملSpatial Structural Change∗
This paper studies the spatial implications of structural change. The secular decline in spending on agricultural goods hurts workers in rural locations and increases the return to moving towards nonagricultural labor markets. We combine detailed spatial data for the U.S. between 1880 and 2000 with a novel quantitative theory to understand this process and to quantify its macroeconomic implicat...
