<> It is not clear that this is a -merge- job, in spite of the constant position within the datasets. You could also -append- them and save yourself the trouble of -reshape-ing...

Juni 2010 21:13 To: statalist@hsphsun2.harvard.edu Subject: st: Best way to construct panel dataset from mutiple cross sectional files. I have separate datasets for each year from 1998 through 2008. Within each dataset, each observation represents a single firm that maintains the exact same observation number across all eleven years (e.g., GM is obs. #9 in the 1998, 1999, 2000, etc. dataset). I would like to create a panel for all 14,247 firms. I think I need to first merge all the datasets and then use the reshape command to go from wide to long form. Is this the best to way to go? Thanks so much.
