LAD Asymptotics under Conditional Heteroskedasticity with Possibly Infinite Error Densities

Cho, Jin Seo; Han, Chirok; Phillips, Peter C.B. - Cowles Foundation for Research in Economics, Yale University - 2009

Least absolute deviations (LAD) estimation of linear time-series models is considered under conditional heteroskedasticity and serial correlation. The limit theory of the LAD estimator is obtained without assuming the finite density condition for the errors that is required in standard LAD...
