Subset of data from Autor, Dorn and Hanson (2013, ADH) that is used to illustrate the confidence intervals implemented in this package.
A list, consisting of a data frame, a vector, and a matrix. The first
ADH$reg, has 1,444 rows and 16 variables. The rows
correspond to 722 commuting zones (CZ) over 2 time periods (1990-1999 and
2000-2007), and the variables are as follows:
Change in the share of working-age population
Change in the share of working-age population employed in manufacturing.
Change in the share of working-age population employed in non-manufacturing.
Change in sectoral U.S. imports from China normalized by U.S. total employment in the corresponding sector, aggregated to regional level. This is the variable of interest in ADH.
Change in sectoral imports from China by rest of the world,
aggregated to regional level. This is the variable used to instrument for
d_tradeotch_pw_lag in ADH.
Regression weights corresponding to start of period CZ share of national populations
State FIPS code
Indicator for 2000-2007
Employment share of manufacturing
percent population college-educated
percent population foreign-born
percent employment among women
percent employment in routine occupations
Offshorability index of occupations in CZ
US Census division of CZ
The second list component, the vector
ADH$sic is a vector of length
770 that gives 4-digit SIC industry codes for the sectors used to construct
the shift-share IV
ADH$W is a 1444-by-700
matrix of shares that correspond to the CZ employment shares in 4-digit SIC
We thank David Dorn for helping us with the construction of the share matrix. The remaining data was obtained from David Dorn's website, http://ddorn.net/data.htm.
