Betreff: st: Generating a new variable....tricky question?
hello,
I have a panel dataset with variables for 88 countries each for 5 time
periods.
E.g.
country year GDP FDI
Algeria 1 x .
Algeria 2 . .
Algeria 3 . .
Algeria 4 . .
Algeria 5 . .
Argentina 1 y .
Argentina 2 . .
Argentina 3 . .
Argentina 4 . .
Argentina 5 . .
etc
etc
Where the dots indicate particular numeric observations. I want to generate
a new variable which for EACH country multiplies FDI by the INITIAL GDP
value in year 1. E.g. for the case of Algeria, FDI in year 1 would be
multiplied by GDP in year 1 (denoted by x), then FDI in year 2 would be
multiplied by GDP in year 1 (denoted by x), then FDI in year 3 would be
multiplied by GDP in year 1 (denoted by x) and so on. Then obviously, once
we get to argentina, it should start multiplying by GDP in argentina's year
1 (denoted by y) and then year 2 FDI in argentina by y and so on.
My question is: How can I generate this variable?
I would really appreciate your help.
