Question
Chapter 21, Problem 2DAP
(a)
To determine
Go to the St. Louis Federal Reserve databased, and find data on the monthly U.S dollar exchange rate to the Chinese yuan (EXCHUS), the Canadian dollar (EXCAUS) and the South Korean won (EXKOUS).
For the most recent 5-year period of data available, use the average, max, min, and standard deviation functions in Excel to calculate the average, highest, and lowest exchange rate values, as well as the standard deviation of the exchange rate to the dollar (this is an absolute measure of the volatility of the exchange rate)
(b)
To determine
Using the maximum and minimum values of each exchange rate over the last five years, calculate the ratio of the difference between the maximum and minimum values to the average level of the exchange rate (expressed as a percentage by multiplying by 100). Based on the results, which of the three countries is most likely to peg its currency to the US dollar? How does this country’s currency compare with the other two?
(c)

(a) Suppose there are two firms 1 and 2, whose abatement costs
are given by c₁(e₁) and c₂ (e₂), where e denotes emissions and
subscripts denote the firm.
We assume that c{(e;) 0 for i = 1,2 and for any
level of emission e we have c₁'(e) # c₂'(e).
Furthermore, assume the two firms make different contributions
towards pollution concentration in a nearby river captured by the
transfer coefficients ε₁ and 2 such that for any level of emission
e we have 2(e) +2 The regulator does not know the resulting
C₁'(e) Τι
environmental damages. Using an analytical approach explain
carefully how the regulator may limit the concentration of
pollution using (i) a Pigouvian tax scheme and (ii) uniform
emissions standards. Discuss the cost-effectiveness of both
approaches to control pollution.

- Exotic Coffee for the Poor? What a Genius Idea! you are a business consultant at a coffee shop. Your team leader came to you one morning with excitement on her face and told you, "Guess what? I have an idea for a great location for our next coffee shop. Think about it, Riceville is a city that has 150,000 people. Most of them are above the age of 16, which means they are potential coffee drinkers. Well, even though the majority of people in that city are making minimum wage and are considered poor, but the good news is that there are no coffee shops in Riceville and the only places you could get coffee there either restaurants or gas stations.

Furthermore, assume an additively separable utility function in consumption C and pollution stock S so that, U(C,S) = u(C) + v(S), where uc > 0; Ucc 0. Note that the first derivative, and the second subscript denotes the second derivative. The evolution of the pollution stock S over time is a function of consumption, decay rate of the stock of pollution & and abatement through the function, g(S) with gs > 0 and 9ss < 0.

- 2. Question The 'Democratic Family' consists of three members {mother m, father f, daughter d}, that have different preferences with respect to how much money X € [0,8] they think should be invested in the new family car. These preferences can be represented by the following utility functions: - Mother m: um(X) = 2X - X² Father f: uf(X) = 10X - X² - Daughter d: ud(X) = 4X - X² Calculate for each family member (f, m, d) the preferred amount of money to invest in the new car denoted by X; for i = {m, f,d}. Assume that (Xf, Xm, Xd) are the three alternatives on which the family must decide. Show that each family member has rational preferences over this domain. Preferences on the family level are determined by pairwise majority voting (all family members vote on two alternatives). Derive the family preference and check whether it is rational. Assume that the final family decision is made by conducting sequential pair- wise majority voting, where the loosing alternative is eliminated. Does…arrow_forward3. Question You invented a new lateral-flow test for asymptomatic Covid-19 detection, where saliva is entered into a test-tube and then the result is shown directly on the device. However, to save on costly chemicals you designed the tests such that it always reports a negative test result. Assume that the incidence rate is 5 per 1000 and that your test is used for detection of asymptomatic cases (without symptoms). (a) Calculate the probability that 100 randomly determined volunteers receive a correct test result by using the AND-rule and the OR-rule. Can your test be qualified as a diagnostic test? (b) The health authorities are investigating the performance of your test. Government guidelines require a specificity (conditional probability to re- ceive a negative test result given that the test-taker is not infected with COVID19) of at least 97% and a sensitivity (conditional probability to receive a positive test result given that the test-taker is infected with COVID-19) of at…arrow_forward3.
