"The loss is evident in the lines at the soup kitchens. And the loss is evident in the homes where unemployed workers, anxious, depressed, sunk in despair, lash out at their loved ones or find solace in alcohol or drugs.”
– Archbishop Thomas Murphy

Endangered Species and Running Out
– Spotted Owl, Marbled Murrelet, Many
Salmonids
– Just plain ran out of big trees to cut
“And then came the spotted owl, and almost overnight the hauling jobs dried up and we had our electricity turned off and finally we received a foreclosure notice on this farm”

Reduce Poverty in Timber dependent counties?
Increase Employment
– by more than one job for each new timber job?
– by one job or less?
5
CGE/IO/SAM multiplier models
– capture all relevant economics
– assumptions on difficult to measure parameters can drive results
• labor mobility (no real migration data)
• openness to trade (interstate trade unmeasured)
• relation of product to labor input (product unmeasured)
6
Nearly no economics imposed on model
Uses available real data
Can’t explain why
but Can measure impact multipliers
and be used to find Long Run

Johansen’s MLE of the possibly cointegrated VAR using the 3 county and 2 state variables.
– lag length
– rank of cointegrating space
– coefficient estimates, incl. coint vectors
– Exclusion and Weak Exogeneity tests

Exclusion of Timber or Poverty
– Not Poverty: Humboldt, Siskyou
– Not Timber: Trinity, Del Norte, Amador,
Tuolumne.
Poverty Weakly exogenous
– Plumas, Mendocino
Increase Timber, INCREASE poverty
– Tehama

Rank 3: Stabile povery unless state level variables change
– Shasta
Only in Lassen of the 11 counties may timber employ reduce AFDC-UP in LR

“Job is a Job”
In four of 11 counties timber jobs shift cointegrating space same as any other job. Poverty same.
100 new timber jobs = 78 jobs 2 years later. Mult is less than 1!
15
100 new timber jobs = 3 less cases of
AFDC-UP or
1% timber jobs increase = 14/100% poverty decrease
Non timber employment does fractionally better
16
Cutting more trees won’t do anything for poverty in the LR and very little in the
SR.
Employment Cutting more trees doesn’t have base like multipliers.
