What I want to do now, is to keep only those observations for each firm
which are part of the longest consecutive streak of existing entries.

This was discussed last fall on this list, and a question that arose then applies to your question also: what would you want done in the case where a firm has two streaks of equal length?

Obs Firm year
1 1 1981
2 1 1980
3 1 1985
4 1 1986
