D

E

The firm will always reduce its variable costs when it adopts new technology.

Understanding the Answer

Let's break down why this is correct

Answer

When a technological advancement reduces marginal costs for a firm in a perfectly competitive market, it means the firm can produce its goods at a lower cost for each additional unit made. This decrease in cost allows the firm to either lower its prices or increase its production level. Lower prices can attract more customers, leading to higher sales, while increased production can help the firm take advantage of economies of scale. For example, if a bakery invests in a new oven that bakes bread faster and cheaper, it can sell more bread at a lower price, benefiting both the firm and consumers. Overall, this advancement can lead to increased competition in the market, benefiting consumers through lower prices and more choices.

Detailed Explanation

In a perfectly competitive market, all firms face the same prices. Other options are incorrect because Some might think that lowering costs lets a firm produce more without changing prices; It's a common belief that if marginal costs drop, average total costs will also drop.
