Shackleton's comment on my earlier article seems to me to raise a number of interesting questions. He is very critical of my methodology and suggests alternative ways of testing Olson's model. He places most emphasis on the need to consider aggregate data on the changing patterns of interest group membership over time. In this short note I do not intend to reply at length to Shackleton's criticisms. Instead, I shall re-examine Olson's analysis using aggregate data on the changing patterns of CBI membership in the last decade.
1 I do not have space here to look at the CBI's precedessors, but Olson's analysis is applied to this period in Grant, W. and Marsh, D., The Confederation of British Industry (London: Hodder and Stoughton, 1977).Google Scholar

It is informative to quote Olson on this point: ‘The cost of voting and signing petitions is thus insignificant and imperceptible to many people… The point is that there is a “threshold” above which costs and returns influence a person's action, and below which they do not.’ Olson, M. Jr., The Logic of Collective Action (Cambridge, Mass.: Harvard University Press, 1971), p. 164.Google Scholar
