Porque as Filas são Ruins

"A lot of things in economics will turn in one way or another on price. Price has a lot going for it as a generalized expression of commitment. The thing we don’t like about, say, first-come, first-serve, is that if someone really wants to get in, they could start lining up now. But the problem is that I don’t really benefit from your expression of interest, whereas if you pay me, we both are benefiting.”
