Starting in 2006 both the post 2002 and post 2006 indicators are one. The baseline of the subdistrict post 2006 interaction includes the fixed effect of post 2002. Since the policy fixed effects of being in the subdistrict after 2002 is identical to table \ref{reg2002} these are omitted from the summary. }
