If you have a nation id variable, just place an "i." in front of the nation id variable in models.  Assuming you are using version 11 or later that will produce dummies for each nation in your model.  If you want permanent dummies, look up tabulate oneway.  If a generate modifier is added after a coma to tabulate, this creates separate dummy variables for every value of a variable.

Dear statalist.

I want to choose oecd members from all countries and make dummy variables.
So I wrote like this way:

gen oecd=1 if country=="Australia" | country=="Austria" |
country=="Belgium" | country=="Canada" | country=="Chile" |
country=="Czech Republic" | country=="Denmark" | country=="Estonia" |
country=="Finland" | country=="France" | country=="Germany" |
country=="Greece" | country=="Hungary" | country=="Iceland" |
country=="Ireland" | country=="Israel" | country=="Italy" |
country=="Japan" | country=="Korea, Republic of" |
country=="Luxembourg" | country=="Mexico" | country=="Netherlands" |
country=="New Zealand" | country=="Norway" | country=="Poland" |
country=="Portugal" | country=="Slovakia" | country=="Slovenia" |
country=="Spain" | country=="Sweden" | country=="Switzerland" |
country=="Turkey" | country==" United Kingdom" | country=="United
States"
replace oecd=2 if oecd==.

Is there more efficient way than mine? I think it's very tough to make
variables.

Thanks.
