A COMPARISON OF TOBIT AND OLS ESTIMATES OF JAPANESE PEANUT IMPORT DEMAND
研究了1973-1988年日本花生进口配额限制下，使用Tobit模型估计需求，并评估忽略配额时OLS估计的偏差，发现OLS会产生有偏结果。
A Tobit analysis is applied to estimate Japanese peanut imports under quota restrictions for the period 1973–1988, and to assess the bias when the presence of quota is ignored by using OLS estimation. The results show that biased estimates are obtained by using OLS in the presence of quota restrictions.
