ADH {ShiftShareSE}

Dataset from Autor, Dorn and Hanson (2013)

Description

Subset of data from Autor, Dorn and Hanson (2013, ADH) that is used to illustrate the confidence intervals implemented in this package.

Usage

ADH

Format

A list, consisting of a data frame, a vector, and a matrix. The first data frame, 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:

d_sh_empl

Change in the share of working-age population

d_sh_empl_mfg

Change in the share of working-age population employed in manufacturing.

d_sh_empl_nmfg

Change in the share of working-age population employed in non-manufacturing.

shock

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.

IV

Change in sectoral imports from China by rest of the world, aggregated to regional level. This is the variable used to instrument for shock, called d_tradeotch_pw_lag in ADH.

weights

Regression weights corresponding to start of period CZ share of national populations

statefip

State FIPS code

czone

CZ number

t2

Indicator for 2000-2007

l_shind_manuf_cbp

Employment share of manufacturing

l_sh_popedu_c

percent population college-educated

l_sh_popfborn

percent population foreign-born

l_sh_empl_f

percent employment among women

l_sh_routine33

percent employment in routine occupations

l_task_outsource

Offshorability index of occupations in CZ

division

US Census division of CZ

The second list component, the vector ADH$sic is a vector of length 770 that gives 4-digit SIC industry codes for the sectors used to construct the shift-share IV ADH$reg$IV. Finally, ADH$W is a 1444-by-700 matrix of shares that correspond to the CZ employment shares in 4-digit SIC sectors.
