I think Aymen means to have the same lags in each equation, but with a
"gappy" structure, for example include the first and third lags, but not
the second (everywhere). Then the VAR-OLS-estimation would still apply.
Vaguely I think there was a discussion about this some time back, but I
don't remember the result. Of course it's still possible to specifiy
this manually as a system and do OLS, but it's not very convenient.
sorry,
sven
