Economics

Pulp fiction has returned as Japanese light novels.

Why do kpop groups have lots of members? Is it only more recent ones that do? Was it always optimal and just more recently is tried/became possible?

Why do artists like charli xcx and taylor swift now release remixes of lead singles after the album with major features. Idea is you can get more hype per hour of work this way. But more precisely you want a hype threshold, such that the consumer is hyped enough to take some action, previously buying the LP, then buying online, now streaming. The change is that the consumer is becoming more informed about the product, and the ‘purchase’ becomes cheaper, as when the spotify subscription is amortized (kinda) over all the songs you stream than month.

How will the lower search costs associated with music streing change the time by which people’s music taste locks in, and how will this change music more generally?

Why are used book stores more densely stocked than new bookstores? Something about economies of scale working differently? Different average prices of stock? Higher variance in willingness to pay for different stock? Just product differentiation between new and used booksellers/what customers want from the two experiences?
