What area represents the firm's profit? e. At which output level are economies of scale exhausted? f. Does this graph most likely represent the long run or the short run? Why?

Gasoline and bicycles are substitutes in consumption. Suppose we increase the federal gasoline tax to $1 per gallon

Initially, the gasoline price rises due to the tax, and the demand curve for bicycles shifts rightward because these goods are substitutes. Then, the bicycle price rises, and the demand curve for gasoline shifts rightward. Assuming the general equilibrium is achieved in both markets after these two steps, which of the following statements is NOT true? A) Partial equilibrium analysis only focuses in the first-round changes in the gasoline market (ignoring the secondary effects that arise from changes in the bicycle market). B) Partial equilibrium analysis would predict a larger shift in the price and quantity demanded for gasoline than a general equilibrium analysis. C) The price increase in gasoline is larger under the general equilibrium approach, but the change in the quantity of gasoline demanded is smaller than under partial equilibrium analysis. D) All of these statements are true.
