Implan Understates Agricultural Input-Output Multipliers: An Application To Potential Agricultural/Green Industry Drought Impacts In Colorado


  • McKean, John R.
  • Spencer, William P.


Synthesized input-output models are widely used by industry and government economists. The IMPLAN program is popular because it provides user access to the base data so that modifications can be made. The Washington survey-based model and IMPLAN for Washington State are compared, and differences in multipliers are traced to differences in final payments leakages. An adjustment technique for IMPLAN is demonstrated. An application is made to a Colorado potential drought impact analysis. More than 51,000 part- and full-time jobs and $1.6 billion of household income are at stake in the Colorado farm and "green industry" sectors.
