Hi Anees,

Thank you for suggesting articles. They are related to my work as well. I was trying to use VAR for panel data but unfortunately couldn't find proper solution to panel var models in Stata. If you have any clue other than I.Love's PVAR.

 

Thanks

Aasim

I have tested the variables for stationary and cointegration. They are stationary at first differance but have unit root at levels. So in my VAR model I am using them in difference. I tried VECM but it fails to include one trend variable (technological growth) which covers affectiveness of labour. If I use 3lags and Var at difference all is fine for other two countries but for one country only LM test fails at 1st lag it works on other two lags. What would you suggest in this case? Any reference which I can use to deal with bit of autocorelation. > > > > > > > > !

It is difficult to test them for stationarity given only 30 obs. but if other research using these variables has focused on their differences rather than their levels, I would heed it. > > Kit > > > Kit Baum | Boston College Economics & DIW Berlin | http://ideas.repec.org/e/pba1.html > An Introduction to Stata Programming | http://www.stata-press.com/books/isp.! > ht! > > ml > An I!
