1. CRRA Utility Function: Constant relative risk aversion, or CRRA, utility function has been extensively used in macroeconomic analysis to represent consumer behavior. It takes the following general form u(x)- where σ is known as the curvature parameter. For the remainder of this question assume that σ>0.

PLEASE EXPLAIN WHY ANSWER IS TRUE OR FALSE: "Risk aversion" implies that investors require higher expected returns on riskier than on less risky securities. a. True b. False When adding a randomly chosen new stock to an existing portfolio, the higher (or more positive) the degree of correlation between the new stock and stocks already in the portfolio, the less the additional stock will reduce the portfolio's risk. a. True b. False An individual stock's diversifiable risk, which is measured...
