- 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?

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.)< (b) Discuss why (a) is useful to understand the reservation wage wд in this economy.< (c) We write WR = WR (b,ẞ,λ) to reveal its dependence on (b,ẞ,λ).

The process of producing paper creates pollution. 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. Assume further that the function describing the marginal abatement cost of emissions is given by MAC 120-E where benefits are measured in dollars and E is the level of emissions. a. 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. Assume an existing emission quota limits emissions to E = 60. Show on the graph why this policy is inefficient. What is the deadweight loss caused by this policy?arrow_forward

What is the unregulated level of pollution for each firm? b. Assume policymakers have decided to cut the level of pollution in half. The way they intend to accomplish this goal is to require both firms to cut their pollution in half. What are the total costs of abatement from the policy?

- Thanks in advance!arrow_forwardI need help figuring this out. I'm pretty sure this is correct?If Zambia is open to international trade in oranges without any restrictions, it will import 180 tons of oranges.I can't figure these two out: 1) Suppose the Zambian government wants to reduce imports to exactly 60 tons of oranges to help domestic producers. A tariff of ???? per ton will achieve this. 2) A tariff set at this level would raise ????in revenue for the Zambian government.arrow_forward16:10 ← BEC 3701 - Assignments-...
