I am sorry that the dataset that I wanted to create was accidentally sent before. I am trying to create the last two columns, where

tsum for id 1 for year 2000=sum(tvol for all for year=2000),
tshare1= tvol/tsum, and tshare2=tvol/(tsum-tvol).

Thanking you all for your cooperation (not least my econ colleagues:) for their generous support).

Best regards,
