- 2. U-To is a price leader in the market for truck rentals. There are many small follower firms that take U-To’s price P as given and then supply truck rentals according to the supply function S(P)=P-50 for P≥50, and S(P)=0 for P<50. The demand for truck rentals is given by QD(P)=100-P. U-To’s cost function is C(QL)=100+40QL. Questions d. Find U-To’s first order condition for profit-maximization. e. Find the profit-maximizing price and quantity chosen by U-To, and the quantity supplied by the follower firms.Be sure to explain your answers. 2. Consider a market for a homogenous good with the following inverse demand function: P = 52 – 20 where Qis total sold quantity on the market. + (a) If there is only one firm serving the market and the firm's cost function is C(O) = 4Q, what quantity will be sold on the market? What will be the market price? What is the firm's profits? Is the market outcome efficient? (b) Suddenly, there is a potential rival firm considering entering the market. It would produce the same good as the incumbent firm and would have an identical variable cost but has a fixed cost of entry, F = 100. The two firms would be faced with a problem of simultaneously deciding on how of the good to sell on the market (the inverse demand function is still the same). Derive both firms' best response functions and draw these in a diagram. Explain the Nash equilibrium in the diagram. (c) Following from (b), what would be the new equilibrium quantity sold in the market and what is the…Suppose that YouYeet is one of over a dozen competitive firms in the Oviedo area that offers moving truck rentals.

Jabari initially produced five trucks, but then decided to increase production to six trucks. The following graph gives the demand curve faced by Jabari's HookNLadder. As the graph shows, in order to sell the additional fire truck, Jabari must lower the price from $160,000 to $120,000 per truck. Notice that Jabari gains revenue from the sale of the additional engine, but at the same time, he loses revenue from the initial five engines because they are all sold at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial five engines by selling at $120,000 rather than $160,000.
