Consider a competitive (C) market for ‘hamburger combos’ (hamburger, fries, and a drink) at a fast food restaurant with the following aggregate demand (PD) and aggregate supply (PS) relationships:
PD =30−0.5QD PS =10+0.5QS
(a) Graph these equations in a Demand/Supply diagram (be sure to show the value of any intercept points and label the axis). Calculate the competitive market equilibrium price (PC) and output (QC), and show them on the graph. Show your calculations.
(b) Suppose that a negative pollution externality in ‘hamburger combos’ exists result- ing from the health damages of air pollution produced in the production process. Calculate the socially efficient equilibrium price (P∗) and output (Q∗) given that the socially efficient demand (MWTP) and supply (MSC) for ’hamburger combos’ is as follows:
MWTP =30−0.5QD MSC = 20 + 0.5QS
(c) Graph your results from part (b) in a new Demand/Supply diagram and show the total social benefits (willingness to pay) and costs from the socially efficient price and output (identify these areas in your diagram using A, B, C, etc.). Calculate and explain the net social value in the socially efficient equilibrium. Show your calculations.
(d) Based on your results in parts (a), (b), and (c) use a new Demand/Supply diagram to show the area of the total social benefits, total social costs, and the dead weight loss (DWL) from the competitive market economy. Calculate and explain the net social value as well as the value of the DWL from the competitive market economy. Show your calculations.

Draw tareks budget constraint and consumption
: Tarek commutes on the subway, and buys all-other-goods (AOG). He has $100 to spend on subway tickets and AOG. The price of AOG is $1, and the price of a subway ride is $1, as well. Draw Tarek’s budget constraint and consumption, making sure to label ..

Assume perfectly competitive firm is producing
: Assume a perfectly competitive firm is producing 300 units of output, P = $10, ATC of the 300th unit is $11, marginal cost of the 300th unit = $10, and AVC of the 300th unit = $9. Based on this information, the firm is:

Aggregate marginal abatement cost and marginal damage
: Consider a pulp mill that emits air and water pollution emissions (E) that impose negative external costs (damages) onto society. The aggregate marginal abatement cost (MAC) and marginal damage (MD) curves have been estimated follows:

Compute the inflation rate
: Given: CPI in 2006 = 160.0; CPI in 2007 = 170.5; CPI in 2008 = 172.4; CPI in 2009 = 168.2.l Compute the inflation rate in 2007, in 2008, and in 2009. Based on the given data and your computations above, in which year did disinflation occur?
