| Abstract: | Existing studies of British trade union membership concentration have used the variance of logs and concentration ratio measures to show a tendency towards increasing concentration. The Herfindahl index is proposed as a more appropriate measure. The annual variation in concentration is analysed by means of the Herfindahl index and shows some fluctuation, particularly prior to 1947. Divergent trends are shown for manual and white-collar membership concentration. An explanation of the aggregate trend and of these different occupational trends is advanced. |
