Graphing Perfect Competition Practice- Microeconomics

Mr. Clifford presents a task to identify the correct graph for a perfectly competitive firm making a profit. He explains that all provided graphs are incorrect and guides students through common mistakes, such as incorrect placement of ATC and MR=MC. He emphasizes the importance of correct labeling and understanding graph elements to avoid errors. The video concludes with a reinforcement of key economic concepts.

What is the main task given by Mr. Clifford in the video?

• To find the right graph for a perfectly competitive firm making a profit.

• To identify the correct graph for a monopoly firm.

• To calculate the profit of a firm using a graph.

• To draw a new graph for a perfectly competitive market.

What common mistake do students make with the first graph?

• Placing ATC below the price line.

• Ignoring the demand curve.

• Producing at MR equals MC but misplacing ATC.

• Labeling the graph incorrectly.

In the second graph, what is the error related to quantity production?

• Producing at MR equals MC but at the wrong price.

• Producing less than MR equals MC.

• Producing at the intersection of ATC and MC.

• Producing more than MR equals MC.

What is the mistake in the third graph regarding the area of profit?

• Showing profit below the ATC line.

• Ignoring the marginal cost curve.

• Calculating profit using the wrong cost curve.

• Going down to minimum ATC instead of ATC and over.

What labeling error is highlighted in the last graph?

• Incorrectly labeling the profit area.

• Mislabeling the demand curve as supply.

• Forgetting to label the axes.

• Switching the labels of marginal cost and ATC.
