1. Explain why the Ricardian Equivalence Theorem is unlikely to hold in an economy that experiences net immigration flows.
2. Demonstrate, with the aid of a diagram, how the Ricardian Equivalence Theorem will not hold for an economy where individuals are debt-constrained.
1) For each of the following, state whether it is True or False. No need to provide an explanation. a) US businesses relies more on the stock market than the bond market for funding. b) US business relies more on indirect finance than Japan. c) US business relies more on bank loans than nonbank loans. d) US business relies more on nonbank loans than Germany. e) US business relies more on direct finance than the UK.

1. Given a system transfer function G(s) = 3s^3 + 2s^2 + s / s^6 + 4s^5+ 3s^4 + 2s^3 + s^2 + 2s + 6 Determine the steady state response of the system to an excitation: 8sin2t + 15sin3t 2. Construct root loci for (i) s^3 + s^2 + (K+2)s + 3K = 0 (ii) s^4 + 6s^3 + 9s^2 + K(s^2 + 4s + 5) = 0 (iii) s^3 + 5Ks^2 +10 = 0 (iv) s^5 + 2s^4 + 3s^3 +2s^2 + s + K = 0 3. Show that the system with rate feedback in Fig. P6.8a may be reduced to system shown in Fig. P6.8b 4. A linear control system is described by G(s) =10^4(s+1) / s^2 + 110s + 10s^3 (i) obtain Bode magnitude and phase plots (ii) calculate G(s) for w=50 and 1000 rad/s 5. Draw a generic block diagram of a closed loop controls system and describe each of the blocks. Document Preview:

1. Give the 3 × 3 matrix that represents the inverse of the transformation in Exercise II.8.
2. Give an example of how two different 3 × 3 homogeneous matrices can represent the same affine transformation.
3. Consider the transformation shown in Figure II.12. Suppose that a function drawF() has been written to draw the F at the origin as shown in the left-hand side of Figure II.12.
a. Give a sequence of pseudo-OpenGL commands that will draw the F as shown on the right-hand side of Figure II.12.
b. Give the 3 × 3 homogeneous matrix that represents the affine transformation shown in the figure.
1. Give a way to multiply two complex numbers together using fewer than four integer multiplication operations.
2. How much storage would be used by the FFT' if we didn't circumvent the storage-management problem with the perfect shuffle?
1. Give an example of a trading economy of scale.
2. Give two examples of diseconomies of scale.
3. Why has the small-firm sector of the economy grown in the 1980s and 1990s?
1. Give a possible use of port migration in Chorus.
2. It is possible to send a message to a port group in Chorus. Does the message go to all the ports in the group, or to a randomly selected port?
3. Chorus has explicit calls to create and delete ports, but only a call for creating port groups (
). Make an educated guess as to why there is no grpDelete.
1. Hettinger Hospital bases its budgets on patient-visits. The hospital’s static budget for March appears below: Budgeted number of patient-visits 8,900 Budgeted variable cost; Supplies (@$10.00 per patient-visits) $89,000 Laundry (@$9.70 per patient-visit) 86,330 Total variable cost 175,330 Budgeted fixed costs; Wages and Salaries 99,840 Occupancy costs 107,840 Total fixed cost 207,680 Total cost $383,010 The total variable cost at the activity level of 9,000 patient-visits per month should be:
