Having made the statement earlier that McCabe's thesis falls down if he assumes an inexorable link between purchase and price rises, it is clearly not enough to explain that this is not my own experience and I hope to be able to produce evidence (in time!) to back up my assertion. This would be evidence to back up my own memory of what was done by Chapman & Hall - nothing more general. However an example of a purchase that did not result in price rises has been pointed out to me: it is the purchase of Gordon & Breach by Taylor & Francis. I have not checked this and indeed (as an independent researcher) it is very difficult for me to do so, but perhaps someone on this list could see if I am correct in assuming that Gordon & Breach prices were not put up dramatically by their new owners.
