dear statalist,
sorry again to bother you with some very stupid question but I'm
getting stuck again on some simple matter that I believe is in the
writing of scalar.
the story is that I have a panel data and I'ld like to generate a new
variable called kstck (by country (cy)).
so I run this loop:
bysort cy: gen kstck = 0
reshape wide gdp gfc kstck, i(cy) j(yr)
* Calculate capital stock from 1990 to 2000 using the following
formula (where gfc* is the investment in year *)
bysort cy: replace kstck1990 = gfc1990
forvalues i = 1991/2000 {
bysort cy: replace kstck`i' = .93*kstck`i-1' + gfc`i'
}
However, it is not giving me the required result of the recursive
summation. why ?
any advice would be most welcome.
and many thanks in advance.
Marwan
