A utility maximizing saver has u(f1, f2) = f11/2f21/2 and earns m1 = 90, m2 = 90. She can save at an interest rate of 25 percent. If she hires an investment advisor she can save at an interest rate of 80 percent. What is the most that she would pay in fees to this advisor?

Let M1 = (Q1, Σ, δ1, q1, F1) and M2 = (Q2, Σ, δ2, r1, F2)...
Let M1 = (Q1, Σ, δ1, q1, F1) and M2 = (Q2, Σ, δ2, r1, F2) be DFA's where Q1 = {q1, q2, q3, q4}, F1 = {q1, q3, q4}, Q2 = {r1, r2, r3} and F2 = {r1, r3}. Assume that the cross product construction has been applied to M1 and M2 to produce a new DFA M = (Q, Σ, δ, s0, F), and that all possible states in M are reachable from s0.

Romeo lives two periods, and he earns m1 =$10,000 in period 1 and m2 =$12,000 in period 2, respectively. His utility function is u(c1; c2) = c1*c2. Answer the following questions. (a) Suppose that market interest rate is 50% (r = 0:5). Write down Romeo‘s budget constraint. How much does he save or borrow in period 1? Calculate. Explain your answer. Draw a diagram, too. (b) The interest rate goes down from 50% to 25%. What happens his saving or...

two masses m1 = 4.70 kg and m2 which has a mass 50.0% that of m1, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m1 and m2 start from rest, after they have each traveled a distance h = 2.90 m, use energy content to determine the following. (a) speed v of the masses (b) magnitude of the tension T in the cord

Block 1 with m1 = 0.127 kg and block 2 with m2 = 0.163 kg are supported on a horizontal frictionless table whose surface is 1.75 m above a horizontal floor as shown in the Figure. Block 1 has an initial speed of v = 5.50 m/s toward block 2 which is initially at rest. A) (7 pts) Block 1 collides with block 2 and coalesces (forms one object). Calculate the velocity of the coalesced object. B) (10 pts) The...

Question 2: Simultaneous quantity choice: Two firms F1 and F2 producea homogeneous product and compete on the same market. The market price isdescribed by the inverse demand curve P= 11−2Q, where Q is total industry output and P is the market price. To keep things simple, suppose that each firm can produce either 1 or 2 units (these are the only possible choices of production).Further suppose that both firms have a constant marginal cost equal to 2, so that the...

1) Define MB, M1, M2 and M3. 2) What is the reason for using these different measures of money supply? 3) Is there a measure of money supply that is NOT affected by the banking multiplier, i.e. that is determined solely by the actions of the Central Bank? 4) Which nominal interest rate is controlled by the Central Bank? How?
