Explanation of Solution

Technically, the statement the “firm’s entire marginal cost curve is its short-run supply curve”, which is not true. The marginal cost curve and its short-run supply curve are different. The short-run supply curve is the firm’s entire marginal cost curve only when the price of the goods is above the minimum point of the average cost curve. A firm must cover its variable cost in the short run.

Economics Concept Introduction

Marginal cost (MC): Marginal cost refers to the amount of additional costs incurred in the process of increasing one more unit of output. Marginal cost curve shows the additional cost for the different levels of output.

Short-run supply curve: In the short run, it is a curve that shows the relationship between the price level in the economy and the supply in the economy by the firms.

“The firm’s entire marginal cost curve is its short-run supply curve.” Is the preceding statement true or false? Why?
For each of the following events identify which of the determinates of demand or supply are affected. Also indicate whether demand or supply is increased or decreased. Why? A stock market crash lowers people’s wealth. Batelco increases the prices of mobile services. Diminishing returns mean rising costs while economies of scale mean falling costs. Therefore, a firm cannot be facing both diminishing returns and economies of scale. Do you agree? Why or why not?
Explain why a firm might want to produce its good even after diminishing marginal returns have set in and marginal cost is on the rise. People often believe that large firms in an industry have cost advantages over small firms in the same industry. For example, they might think a big oil company has a cost advantage over a small oil company. For this to be true, what condition must exist? Explain your answer.
