Exercise 5: Aggregate Demand and Consumers' Surplus There are three types of consumers. Demand for the first group of consumer is d₁ (p) = 4 demand for the second consumer group is d₂ (p) = demand for the third consumer group is d3 (p) 60-3p if p < 20 0 otherwise 100-2p 0 if p < 50 otherwise 200-5p 0 if p < 40 otherwise 1. Find the aggregate demand function, D(p) = d₁ (p) + d₂ (p) +d3(p). 2. Draw the graph of the aggregate demand function D(p) and clearly mark all important points. Follow the convention in economics and put quantity on the horizontal axis and price on the vertical axis. 3. For the aggregate demand function, D(p), that you found in part 1, find the corresponding inverse aggregate demand function, P(Q). 4. What is the marginal social value of the 90-th unit of the good, MSV (90)? 5. What is the social value of Q = 90 units of the good, SV (90)?

Imagine you are the mayor of a town and you are trying to decide if you should pay for a fireworks show. Your staff survey your 400 citizens who say that they each value a fireworks show at $10. The fireworks show only costs $3,000 so you put on the show but when you ask for donations to pay for the fireworks you only receive $25 total. What does this result show? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. You staff's survey must have overestimated the value of a fireworks show. b The fireworks cost must have been greater than their economic benefit. The firework show suffered from the Tragedy of the Commons problems d The town's citizens were free-riders.
