3. Which is faster, red or green cars?
You are a purchasing manager at a large car dealership in a busy urban area. You purchase on average 250 cars monthly for the dealership. People are buying new and used cars from your dealership regularly, and business is doing well. Most of your customers are average middle-income households, and they typically purchase bigger cars that are pricey. Your boss, Natalya, invited you for lunch to discuss the next big purchase in preparation for the big Summer sales event. While chatting about the business, Natalya told you the following: "While surfing social media today, I read a government report that says the economy is growing and inflation is rising. As the economy continues to grow due to an increase in consumption by consumers, the prices are expected to rise to a higher level than usual. The report also said that the increase in consumption has caused a shortage in the auto industry, which I think might be good for us (or bad, I don’t know.)…
1. Homemade Lasagna and the Pursuit for Knowledge
Your sister, Jamila, a newly appointed human resource manager at a fast-growing assisted living facility, was sitting with you at the dinner table. While you were enjoying a homemade Lasagna and watching TV together, a news report stated that "According to government officials, we are now headed into a recession that could last up to 10 months. The decline in economic activities is expected to affect all major industries."
Your sister raised her eyebrows and showed an expression of confusion as she looked at you and stated, "Oh dear, what should I do now as an HR manager? My company is opening a large facility in a couple of months, and we need at least 60 people to run it. I oversee finding those people, but now I am afraid of doing so because it looks like the economy is in trouble. So, dear brother, help me understand a couple of things:"
First, what on earth is a “recession”, and how does it affect the economy?

Consider the simple discrete job search model that we studied in class. Only the
unemployed can receive one offer per period from F(w) that is a uniform distribution on
[0,2]. There is a constant probability of being laid off at the end of each period while
employed. Assume that she can get a new offer right away when laid off. We want to
understand the reservation wage, WR, in this model. Assume that u(c) = c. The
parameters are a discount factor ẞ and an unemployment benefit b.R and show that T is contraction on [0, ∞). Explicitly state
any additional assumptions that you may need.(Grading guide line: 5pt for the
exact form of T, 10pt for showing contraction, and 5pt for stating correct
assumptions.)<

Assume that the marginal damage function for pollution is given by: MDF = 3E where damages are measured in dollars and E is the level of emissions.

Graph the marginal damage function (MDF) and the marginal abatement cost function (MAC). b. What is the unregulated level of emissions Eu? What is the social welfare of this emissions level? c.
