Hi Oliver, 

Thank you for your kind reply!

I am not quite sure whether I got your hint or not...maybe my explanation
was just not clear enough, sorry about that!!!
I think my case is slightly different from what you were describing
because I am not interested in the missing data between 2003 and 2007.
In that case, as you said, I would just fit a line.
What I am trying to impute are the missing data inside the year 2003 and
2007 respectively. 
And things are made even more complicated by the fact that for the main
explanatory variable of my model I have got only observations for the year
2003 but not for 2007. That's why I was thinking about multiple imputation!
But maybe you are right, I just have too many missing data.

Best,

Veronica
