Check match of activist directors to Equilar

[iangow]

We identify 1,318 activist directors (of our full sample of \Sexpr{dirs$all_dirs}) on Equilar; we find that some activist directors leave within a year (e.g., if the firm is acquired) and Equilar appears not to capture most such directors, as they often do not appear in the proxy statement (DEF 14A), which is the primary source for Equilar's data. % Actually some of these directors were categorized as "activism" or "board demand" depending on when they were appointed as directors.

I think activist directors should always go in this sample as activist directors.

> temp <- new.dir.data %>% filter(activist_director) %>% select(company_id, executive_id, period, activism_firm, activist_demand_firm, activist_director_firm, activist_director, category) %>% collect()
> table(temp$category, temp$activist_director)

                                   TRUE
  New directors: No activism          0
  New directors: Other activism       0
  New directors: Activist director 1312

It seems that all activist directors are categorized as activist director now.
