Abstract
The paper develops and explores tests, based on standard moment specif ications, for the identifiability of parameters apparently estimable b y instrumental variables. An asymptotic expansion under standard restr ictive assumptions on the error distribution suggests a correction to the asymptotic distribution. A small sampling experiment indicates tha t the tests are of use.
