Estimation in Dynamic Linear Regression Models with Infinite Variance Errors

Keith Knight

Econometric Theory, 1993, vol. 9, issue 04, pages 570-588

Abstract: This paper considers the asymptotic behavior of M-estimates in a dynamic linear regression model where the errors have infinite second moments but the exogenous regressors satisfy the standard assumptions. It is shown that under certain conditions, the estimates of the parameters corresponding to the exogenous regressors are asymptotically normal and converge to the true values at the standard n rate.
