Why does specialization require a convenient means of exchanging goods?

Question

Quizplus · Accepted Answer

The Answer is As consumers, individuals prefer to have a wide range of products to satisfy their desires.However, when individuals specialize in production, they focus their efforts on producing one or a few goods.This limited range of production does not match their preferences in consumption.Therefore, individuals must be able to exchange the goods that they specialize in for other goods that they desire to consume.Without a convenient means of exchanging goods, individuals could only consume what they produce.Instead, individuals would be jacks-of-all-trades producing a wide variety of products for their own consumption.There would be little incentive to specialize and to take advantage of the resulting increase in productivity.
