The accompanying diagram illustrates a taxi driver's individual supply curve (assume that each taxi ride is the same distance).a. Suppose the city sets the price of taxi rides at $\$ 4$ per ride, and at $\$ 4$ the taxi driver is able to sell as many taxi rides as he desires. What is this taxi driver's producer surplus? (Recall that the area of a right triangle is $1 / 2 \times$ the height of the triangle $\times$ the base of the triangle.) b. Suppose that the city keeps the price of a taxi ride set at $\$ 4,$ but it decides to charge taxi drivers a "licensing fee." What is the maximum licensing fee the city could extract from this taxi driver? c. Suppose that the city allowed the price of taxi rides to increase to $\$ 8$ per ride. Again assume that, at this price, the taxi driver sells as many rides as he is willing to offer. How much producer surplus does an individual taxi driver now get? What is the maximum licensing fee the city could charge this taxi driver?

Key Concepts

Area Calculation in Graphs

Area calculation methods, such as finding the area of a right triangle using the formula 1/2 × base × height, are important in microeconomics for quantifying measures like producer surplus on supply and demand graphs. This approach allows us to translate changes in prices and quantities into monetary benefits or costs.

Producer Surplus

Producer surplus is the extra benefit producers receive when they sell a product at a market price that is higher than the minimum price they would accept. Graphically, it is represented as the area above the supply curve and below the actual price received, capturing the difference between the price and the producer's cost for each unit sold.

Supply Curve

The supply curve is a graphical representation that shows the relationship between the price of a product and the quantity that producers are willing to supply. Typically upward sloping, it reflects how higher prices encourage producers to offer more of the product, as the profitability of producing additional units increases.

Price Controls

Price controls are government-imposed limits on the prices that can be charged for goods or services. They can include price floors or ceilings, affecting market outcomes by altering the balance of supply and demand. When prices are set above or below the equilibrium, they can lead to additional measures or adjustments in market operations.
