```Tim is correct; thanks!

I think Nick meant:

gen partnerprofit = profit[5] in 3

But following this logic, and if your dataset is not large, you could do it in a loop, I think:

gen partnerprofit = .
forval i=1/`=c(N)' {

local partnerid = partnerid[`i']
replace partnerprofit = profit[`partnerid'] in `i'

}

where I assume you have a partnerid variable which gives you the observation number of the partner.

If your id's do not go in 1,2,3,...,n, however, you may need to do a bit more programming... and probably -merge- is the easiest.

Nick Cox

If the problem is just this, the solution would be

gen partnerprofit = profit[5] in 13

In general, think about a -merge-.

How can I write the value of the variable called profit for e.g.,
subject i as the value into another variable called "partnerprofit" of
another subject j?

For example: I am subject 3, my partner is subject 5; his profit is 13,
now I would like to stata write in my "partnerprofit" the value 13.
