Yes. It does, but actually when I try without any additional calculation
or generation of variables... There Is no observations...
xi: xtabond res2 capacita SFTPW USFTPW FTNPW TFTW ptemporales inno
gradolic i.ISIC
xi: xtabond res2 l(0/1).capacita l(0/1).ptemporales, lags(1)
no observations
r(2000);
All variables are for two periods (years)
