New Distribution Theory for the Estimation of Structural Break Point in Mean
主讲人 Jun Yu 简介 <div>Based on the Girsanov theorem, this paper obtains the exact distribution of&nbsp;the maximum likelihood estimator of structural break point in a continuous time&nbsp;model. The exact distribution is asymmetric and tri-modal, indicating that the&nbsp;estimator is biased. These two properties are also found in the ?nite sample distribution of the least squares (LS) estimator of structural break point in the discrete&nbsp;time model, suggesting the classical long-span asymptotic theory is inadequate.&nbsp;The paper then builds a continuous time approximation to the discrete time model&nbsp;and develops an in-?ll asymptotic theory for the LS estimator. The in-?ll asymptotic distribution is asymmetric and tri-modal and delivers good approximations&nbsp;to the ?nite sample distribution. To reduce the bias in the estimation of both the&nbsp;continuous time and the discrete time models, a simulation-based method based&nbsp;on the indirect estimation (IE) approach is proposed. Monte Carlo studies show&nbsp;that IE achieves substantial bias reductions.</div>
