Pricing at the British Library
At the British Library, the special exhibition about Georgian England has a concession (old folks) price of ₤7, but also a listed concession (gift) price of ₤8. With the latter, one gets a receipt and can deduct the ₤8 from one’s income at tax time. If one is in the 20 percent bracket (taxable income from almost nothing up to ₤32,000), the net admission price is ₤6.40. So the incidence of the subsidy is typically shared nicely by the library and the taxpayer. But for the highest-income visitors — tax rate of 40 percent — the overwhelming share of the benefit goes to the taxpayer. I’ve never seen this double-pricing scheme made so explicit — and the sharing of the gains made so clear — in the U.S.
