On adding over-identifying instrumental variables to simultaneous equations

Author

Listed:
  • Hendry, David F.

Abstract

Reducing the number of over-identifying instruments, or adding them to a structural equation, increases estimation dispersion. Added instruments should be insignificant under correct specification, with parameter estimates nearly unaffected, confirmed by Monte Carlo. Selecting instruments does not affect these results.
