Consider a town in which only two residents, Daniel and Gabrielle, own wells that produce water safe for drinking. Daniel and Gabrielle can pump and
sell as much water as they want at no cost. For them, total revenue equals profit. The following table shows the town's demand schedule for water.

- 3. Working with Numbers and Graphs Q4 The following graph shows the marginal cost (MC) and average total cost (ATC) and the initial demand (D₁) curves of a perfectly competitive firm. Suppose this firm forms a cartel with other firms in the industry. Because of the cartel agreement, it has been assigned a production quota of 25 units. The cartel price is $85 per unit of output. You may use the purple rectangle (diamond symbols) to help you answer the questions that follow. You will not be graded on any changes you make to the graph.arrow_forward5.

Barriers to entry A monopoly, unlike a perfectly competitive firm, has some market power. Thus, it can raise its price, within limits, without quantity demanded falling to zero. The main way monopolies retain their market power is through barriers to entry, which prevent other companies from entering monopolized markets and competing for customers. Consider the market for diamonds. Throughout much of the twentieth century, South Africa's De Beers group was viewed as a monopoly, because it controlled a large percentage of diamond production and sales. Which of the following best explains the barriers to entry that exist in this scenario? O Control of essential resources O Legal restrictions O Economies of scalearrow_forward

In order to increase its profit, the firm will OA. raise its price and move to the segment of the demand line where PED exceeds 1 in absolute value.
