Shift & Share Exercise Option II / Powerpoint
Alternative S&S Exercise
Gary W. Smith, Department of Agricultural Economics
Washington State University Cooperative Extension
has provided us with extensive
shift and share information for Washington counties. You just have to
select your county and
the period for your analysis and the remainder is done for you:
Analysis Applications of County Employment Growth within Washington
"Welcome to the WSU Cooperative Extension Northwest Income Indicators
Project (NIIP) experimental shift-share analysis web page.
[...] The shift-share results you will derive here offer a
thumbnail guide to examining the sources of growth and
changing compostion of local employment among the major
The program will compile and output a
tabular summary of shift-share results based on the
options you choose, a tailored report on how the results
may be interpreted, and a customized technical
summary of how the results are derived...!"
[data up to 2000 as of October 2002]
- Please select two periods, namely 1980-1990 and 1990-2000.
[If there are
others in the class who selected the same county as you, please contact
them and decide on different periods for your respective analyses;
i.e. everyone selects two periods which are as least 2 years but not
longer than 10 years. The idea is that, together, you are generating more
results which will be meaningful for all of you.]
- You need to get an understanding of the terminology used and the
numerical results you are receiving.
- Develop a multi-coordinate graph similar to this
one (Click!) for at least 5 industries and your 2 periods.
You may use Powerpoint, any other graphic software or paper, a ruler and
- Establish the table which shows the different characteristics of your
5 industries for the two different periods.
Interpret your results. In what ways do the 5 different industries differ
in their "contributions" to regional growth and the "total shift" through
their composition and differential effects and
what kind of changes (if any) can you detect between the two different
periods of time.
