Question

Suppose that at prices of $1, $2, $3, $4, and $5 for product Z, the corresponding quantities supplied are 3, 4, 5, 6, and 7 units, respectively. Which of the following would increase the quantities supplied of Z to, say, 6, 8, 10, 12, and 14 units at these prices?A. improved technology for producing ZB. an increase in the prices of the reasources used to make ZC. an increase in the excise tax on product ZD. increase in the incomes of the buyers of Z

Answer 1

A.

Step-by-step explanation:

An improve in technology will allow firms to produce in an effective way therefore, with the same resources, firms will produce more units. This will cause an increase in total supply: at the same price, firms will offer more units. In this case, at prices $1, $2, $3, $4 and $5 the new quantities will be 6,8,10,12. In the demand and supply graph, this looks as shift to the right of the supply curve (figure attached).

It is not option B because the problem says increase in quantities "at these prices". It is not option C because an increase in taxes will increase costs of production, thus firms will decrease units of production. It is not option D because changes in income will affect demand.
