st: GOOGLE ANSWERS FORWARDED

Someone @ google answers asks:

Ok, I'm trying to run a fixed-effects panel in stata. My regression: (where var1 is the depend. variable)

(PLEASE SEE DATA AT END) - Data pasted from excel into stata via editor Stata commands were as follows:

"tsset id year" "gen var1 = ln(x3)" "gen var2 = ln(var 1[_n-1])" ie. require ln(x3 i,t-1) "gen var3 = ln(x2)" "gen var4 = ln(5 +x1)"

xtreg var1 var2 var3 var4, i(id), fe

Now for the coefficient on var2 I get 0.177, and I'm looking for something around the 0.5 region. I've gone wrong somewhere - can someone please help??? It's pretty urgent as I need this by Thursday morning at latest. If it helps, I'm trying to estiamte the model on page 1146 for OECD countries, (but with my own data) in Islam's paper: "Growth Empirics: A Panel Data Approach" (1995) I'm online all the time, so if necessarty, I can clarify things beforehand.

Thanks for your help,
