The Sharpe ratio of an asset Alpha is 0.8. Alpha has and expected return of 12% and a standard deviation of 20%. Youhavebeen tasked to arrive at the expected return of an asset Gamma. Themarketreturn in this economy is 14% and the beta (systematic risk) of Gamma with market return is 1.4. What is the expected return of asset Gamma?

Consider the long-run model of a closed economy with a marginal propensity to consume of 0.8.

a. Public saving (Sg):
b. Private saving (Sp):
c. National Saving (S):
d. Investment (I)

The Kretovich Company had a quick ratio of 0.8, a current ratio of 4.0, a days' sales outstanding of 36.5 days (based on a 365-day year), total current assets of $920,000, and cash and marketable securities of $95,000. What were Kretovich's annual sales? Do not round intermediate calculations. Round your answer to the nearest dollar.

Suppose the stock in Watta Corporation has a beta of 0.8. The market risk premium is 6 percent, and the risk-free rate is 3 percent. Watta’s dividend will be $1.20 per share next year and the dividend is expected to grow at 6 percent indefinitely. The stock currently sells for $45 per share. What is Watta’s cost of equity by the CAPM? ______%

Suppose the market values of Watta’s debt and equity are $10 million and $20 million respectively. Its cost of debt is 9 percent before taxes and the tax rate is 35 percent. What is its WACC? Please use the cost of equity by the CAPM in this question.

Consider a hypothetical economy where: • C(Yd) = 105 + 0.8 × (Y − T) • I(r) = 74 − 1 × r • G = 65 • T = 50 1. Using the information above, write out the planned Aggregate Expenditure equation. 2. Write down an expression for the Investment-Savings (IS) Curve. 3. Assume that inflation is zero, so that i = r. This economy’s central bank follows a given Monetary Policy Rule: r = i = 0.003 × Y + 0.001 × P where P is the price level. Given this and the expression for the IS Curve, write down an expression for the Aggregate Demand Curve. 4. Suppose that the price level (P) is 1000. What is the equilibrium value of aggregate income, Y ? 5. What are the equilibrium values of the interest rate, r, and investment, I? 6. Suppose that the price level (P) falls to 500. What is the equilibrium value of aggregate income, Y ? 7. What are the new equilibrium values of the interest rate, r, and investment, I? 8. Discuss why the change in the price level has the identified impacts on Y , r and I
