502 observations (<5%) valued at 1. further, for the year of 2000-2002,
the missing value rate is 61.19%, 31.91%, and 13.33%, respectively. for
other variables of the regression, i can get relatively complete data
value of each observation. therefore, is it still necessary to include
this dummy in my regression? thanks!

What is this dummy variable supposed to measure?
