Public Member Functions
	PublicTrackerMarket (const Creativity &creativity, eris::SharedMember< Book > b)
	Constructs a PublicTrackerMarket that sells copies of the given Book at marginal cost of the lower of `unit_cost` or `piracy_cost`.

virtual void	added () override
	Sets the initial price and registers this as the book's market when added to the simulation.

virtual void	interAdvance () override
	Updates the market price of the book to the minimum of unit_cost or piracy_cost (in case those changed for the upcoming period).

virtual void	intraFinish () override
	Overrides BookMarket finish to just discard proceeds instead of transferring them to the author: since price is at marginal cost, net proceeds will come out to 0 anyway, so there is never any profit to redistribute. More...

Detailed Description

This class extends BookMarket by always pricing the book at marginal cost (and thus never has any profits).

It is created by PublicTracker for books that are taken off (or are never placed on) the market by authors.

Member Function Documentation

§ intraFinish()

virtual void creativity::PublicTrackerMarket::intraFinish ( )

overridevirtual

Overrides BookMarket finish to just discard proceeds instead of transferring them to the author: since price is at marginal cost, net proceeds will come out to 0 anyway, so there is never any profit to redistribute.

(Technically, the proceeds should be transferred to the PublicTracker, which should also subtract costs, but we just skip that step by just clearing any proceeds).

Reimplemented from creativity::BookMarket.
