Recent data suggests that, as of 2013, the rate of growth predicted by Moore’s Law no longer holds. Growth has slowed to a doubling time of approximately three years. Find the new function that takes that longer doubling time into account.
Suppose that I years from now, one investment plan will be generating profit at the rate of P1'(t)= 90e0.1t thousand dollars per year, while a second investment will be generating profit at the rate of P2'(t)= 140e0.07t thousand dollars per year. (a) For how many years does the rate of profitability of the second investment exceed that of the first? (b) Compute the net excess profit assuming that you invest in the second plan for the time period determined in part (a). (c) Sketch the rate of profitability curves y = P1'(t) and y = P2'(t) and shade the region whose area represents the net excess profit computed in part (b).
Suppose that the real money demand function is L(Yr+ ? ?=0.3Yr+c) Where Y is real output, r is the real interest rate, and πe is the expected rate of inflation. Real output is constant over time at Y = 1500. The real interest rate is fixed in the goods market at r = 0.5 per year. (a) Suppose that the nominal money supply is growing at the rate of 10% per year and that this growth rate is expected to persist for ever. Currently, the nominal money supply is M = 400. What are the values of the real money supply and the current price level? (Hint: What is the value of the expected inflation rate that enters the money demand function?)
Find the marginal -revenue function if the demand function is p=(15)/(ln(q+4)).
Suppose the Marginal product of labor in the economy is given by MPN= .002(16,000-N), while the supply of labor is N=1000 + 1000w. Find the market clearing real wage rate and level of employment. What happens to the wage rate and employment if wealth rises, reducing the supply of labor to N= 500 + 1000w? As in (a), what is the unemployment rate if real wage is 1 more than the equilibrium wage? (hint: solve the real wage and then add it by 1, then find the difference of quantity of labor supplied and demanded).
Determine the AV at time 9 of $100 invested at time 4 given the accumulation function a(t)=0.05t2+1.
The quoted futures price corresponds to a forward rate of 8% per annum with quarterly compounding and actual/360. The parameters for Black’s model are therefore:Fk = 0.08, K=0.08, R=0.075, tk=0.75, SDk=0.15and P(0,tk+1)=e-0.075x1=0.9277 . Use these information to estimate the call price.
Find the present value of a continuous stream of income over 3 years if the rate of income is 80e-0.08t thousand dollars per year at time t and the interest rate is 11%.
A continuous stream of income is being produced at the constant rate of $8,000 per year. Find the present value of the income generated during the time from t = 0 to t = 6 years, with a 12% interest rate.
Consider the function price = $100 – ($3/yr) x time. The initial value of this function is
