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.
