A mobilization by French publishers at last month’s Frankfurt Book Fair has proven successful: Last Tuesday the French Senate voted for a law imposing a fixed price on eBooks for sale within French territory – that is, just as with print books in France, everyone has to sell a given ebook for the same price. No discounting.
Here is more; solve for the equilibrium! Oddly, in the United States, the market has been moving toward an approximation of this outcome, at least for new books, though not for classics. Probably both prices need to fall, though perhaps they will in rough tandem. I believe the equilibrium value of a hardcover or e-version of a bestseller is below $10, given the recent shift out of the supply curve for the written word.
