Question

maynard, jewel, vivi, and cindy are trying to form a band. they each have some basic skills on most instruments, so their current plan is for each of them to rotate among vocals, guitar, bass, and drums. after a year of practice and rehearsals the band still sounds awful. maynard cannot keep a steady beat when on bass or drums, vivi sounds terrible on everything except the bass, nobody except jewel can remember all the chords on guitar, and even cindy’s own mother thinks her singing sounds like a dying cow. at their current rate, they expect it will be several years before they are good enough to land their first paid performance. none of them have enough money saved up to last that long. they all know you are taking economics and ask your advice. what would you say to them? continue with the current plan, as economies of scale should eventually kick in. change the rotation to be random rather than equal to take advantage of heteroskedasticity. invest their remaining savings in new instruments, as they are at a point where the marginal product of capital exceeds the marginal product of labor. abandon the band, as continued practice is doomed to suffer diminishing marginal returns. have each member specialize in the role that they are best in to take advantage of benefits from specialization.

Explanation:

The core issue is leveraging each member's comparative advantage to maximize the band's quality, which aligns with the economic principle of specialization. Each member has a demonstrated relative strength: Jewel with guitar chords, Vivi with bass, and the others have clear weaknesses in other roles. Specialization allows them to focus on their best skills, improving overall performance instead of wasting effort on roles they are bad at. The other options are incorrect: economies of scale don't apply here, heteroskedasticity is a statistical term irrelevant to this context, investing in capital is not feasible with limited savings, and abandoning the band is unnecessary when specialization can fix their issues.

Answer:

Have each member specialize in the role that they are best in to take advantage of benefits from specialization.
