Avi and Maya are the only two consumers in an economy. Avi’s demand for apples is given by the equation xA(p) = 6 − p, where p is the per unit price of apple. Maya’s demand for apples is given by the equation xB (p) = 10 − p.
(a) Derive the aggregate demand x(p) = xA(p)+xB(p). Draw the aggregate demand where price of apples is on the vertical axis and the aggregate quantity consumed is on the horizontal axis.
(b) Suppose p = 4. Calculate the consumers’ surplus at this price.
(c) Find the elasticity of aggregate demand with respect to price when p = 4.

Suppose that the demand for apples is perfectly elastic and the government levies a tax on the producers of apples. Assume that the supply of apples is neither perfectly elastic nor perfectly inelastic. 1. How will the price paid by consumers change? Is this change bigger or smaller than the price change that would result if the demand for apples were not perfectly elastic? 2. How will the quantity of apples consumed change because of the tax? Is this change...

1)Suppose Demand for Apples (in bushels) is given by Q = 90-P and Supply is given by Q = P. The market for apples is dominated by a single, monopolistic firm "NYC Apples". Suppose you could regulate the market for Apples and impose a price ceiling. What price would maximize social welfare (combined producer and consumer surplus)? 2)Suppose Demand for Apples (in bushels) is given by Q = 90-P and Supply is given by Q = P. The market for...
