Abstract

Conventional parametric approach to dealing with zero expenditures is not robust to heteroscedastic and/or non-normal error structure. This paper applies symmetrically censored least squares estimation as a robust approach to dealing with zero expenditures on mobile communications in Seoul, Korea. The result of specification test indicates the robust approach outperforms the parametric approach significantly.
