Consumer and producer surplus in a monopoly diagram
What is the loss of consumer and producer surplus called?
Deadweight loss
In this diagram where is industry output in perfect competition? And output in a monopoly?
Point A for perfect competition
Point B for monopoly
-monopoly restricts output from Q1 to Q2 and prices prices from P1 to P2
Deadweight loss def?
Loss of economic welfare when the maximum attainable levels of total welfare fails to be achieved
When happens when a monopoly raises prices?
Increase of producer surplus at expense of consumer surplus
What is deadweight loss evidence of?

Both the shaded triangles
Diagram to illustrate price discrimination and the transfer of consumer surplus
Diagram for a combined market after price discrimination?
Describe this diagram
(Of the combined marker after price discrimination)
The average revenue curves of male and female are added together
The marginal curves of male and female have also been added together
For the combined market the marginal cost slopes upwards depicting the impact of the law of diminishing returns
Diagram for price discrimination (the limiting case where each customer is charged the maximum they are willing to pay)
What does this diagram highlight?
A situation where all the consumer surplus is transferred to producer surplus (every customer charged the max they are willing to pay)
In the absence of price discrimination where should the firm produce?
Q1 where MC=MR
Describe how this diagram depicts how the poorest customers can benefit from price discrimination
Each time the firm sells to one more customer total sales revenue rises by the extra units sold multiplied by the price the customer pays(customers are changed different prices to different customers)
-the absence of price discrimination the firms AR curve continues to be the demand curve and the MR curve is below the ar curve
However with price discrimination the demand curve if the same as the MR curve
