[Related to the Chapter Opener] In the chapter opener it is mentioned that: "For example, in early 2020 , if you wanted to invest in a corporate bond that matured in 2026 , you could earn an interest rate of 2.0% on a bond issued by Apple Inc., or you could earn an interest rate of 8.9% on a bond issued by U.S. Steel."\nThe Apple bond was rated Aa1 by Moody's, while the U.S. Steel bond was rated B3.\nDo these ratings help explain the difference in the yields on the firms' bonds noted in the chapter opener?\nA. No, credit ratings do not impact or explain interest rates on bonds, they only reflect interest rate risk in the overall economy.\nB. No, the ratings indicate that the Apple Inc. bond has a greater default risk than the U.S. Steel bond, yet it has a lower yield.\nC. Yes, the ratings indicate that the U.S. Steel bond has a greater default risk than the Apple Inc. bond, therefore a higher yield on this bond makes sense.\nD. Yes, the ratings indicate that the Apple Inc. bond has a greater default risk than the U.S. Steel bond, therefore a higher yield on this bond makes sense.

Consider a model of disease spread that contains a compartment for the density of susceptible (S) individuals, infective (I) individuals, and recovered (R) individuals. This disease is like smallpox or many other diseases where you are immune once you've had it. For this reason, recovered individuals (R) are the best people to care for and to treat the infectives. These treatments and care increase recovery rates. Assume there are no births or deaths. a. How would you modify the SIR equations to account for this new interaction between I and R? Let Î² be the average rate at which infectives are infecting recovereds, and Î³ is the recovery rate of infectives that receive no care. b. Is your total density of individuals, N = S + I + R, constant in time or does it change in time? Use your differential equations above to prove your answer. Use this to reduce the number of independent variables and equations. c. Find all of the fixed points for this system. d. What is the interaction matrix for this system? e. To see if a newly introduced disease will spread, which fixed point should you examine and perform a stability analysis around? To analyze the stability of this system, should you use the Jacobian calculated according to the standard method below in the REMINDER or use the interaction matrix, or is either ok? f. Calculate eigenvalues to see if a disease will spread when newly introduced into a population. Determine whether the Ro parameter from class or some new version of it will dictate the chances of spread. Explain why biologically. REMINDER: The Jacobian for a pair of predator-prey equations is defined by: J(X*) = [f1(N,P) / f1(N,P)] [f2(N,P) / f2(N,P)] where N' = rN - CNP = f1(N,P) dt P' = CNP - ZP = f2(N,P) dt The Jacobian for the SIR model, for example, is derived similarly but starting from: S' = -Î²SI dt I' = Î²SI - Î³I dt R' = Î³I dt
