If price were not used as a rationing device, would something else have to be used? why or why not? how might tickets for a concert be rationed without using price?

Price rationing is very important for counting or determining the worth of a service or good.

Explanation:

According to me price rationing is important factor for determining the cost and actual value of any good or service. Fixing price for a service or good gives the consumer a sense of trust that he/she is paying the same cost that other consumer is paying.

Like in the past time, there was barter system of selling and buying goods and services. But this system of not as appropriate as price rationing is.

If the price rationing system will not available then people must use the old barter system to buy a ticket of a concert.
