I find that interesting. Did your case study involve Motherwell? I've always be led to believe that the numerous Boyle initiatives involving reduced pricing have lowered revenue and thus been an expensive failure.
Another thing that you probably looked into would be the amount of travel/expense the average fan incurs for home matches. For example clubs like say Falkirk, Stirling, Arbroath, Raith etc probably draw the lion's share of their support from the home town and travel costs will be on average very low. Thus when you bracket expense of travel and entrance costs together a reduction in gate money will be a large percentage to fans of those example clubs.
Whereas clubs like Aberdeen, Hearts, Hibs, St Johnstone, Ross Co plus maybe Killie, Ayr etc will have a much higher percentage of fans travelling extra distance. Any reduction in gate money will be of a much lower percentage of overall matchday cost. I would suggest that Jags fans might tend more to the latter camp. In short the incentive of attending a game at Firhill by reducing the gate price may not have the desired effect if the cost of travel remains static or, as has happened from the turn of the year, considerably increased.
