| ''Which null hypothesis do overidentification restrictions actually test?'' |
| ( 2008, Vol. 3 No.76 ) |
| |
| |
| In this note I investigate which alternatives are detected by over-identifying restrictions tests, when we test the null hypothesis that all excluded instruments are exogenous. A reformulated null hypothesis will result in a consistent test. |
