Which of the following is consistent with the capm and efficient capital markets? a security with only systematic risk has an expected return that exceeds the risk-free interest rate. a security with a beta of 1 has a return last year of 8% when the market has a return of 12%. small stocks with a beta of 1.5 tend to have higher returns on average than large stocks with a beta of 1.5. a security with only diversifiable risk has an expected return that exceeds the risk-free interest rate.

The media specialist suggests a library reading program that will correlate highly with the teaching program and reward the students as they read. the rewards will be provided by the business community. a pencil carrier will be the reward for having read 25 books, a baseball cap the reward for having read 30 books, a tee shirt for 50 books, and a backpack for having read 100 books. the media specialist's suggestion is based on her knowledge that:

David consumes two things: gasoline (g) and bread (b). david's utility function is u(g, b) = 10g^0.25 b^0.75. use the lagrange technique to solve for david's optimal choices of gasoline and bread as a function of the price of gasoline, p_g, the price of bread, p_b, and his income m. with recent decrease in the price of gasoline (maybe due to external shock such as shale gas production) does david increase his consumption of gasoline? for david, how does partial differential g/partial differential p_g depend on his income m? that is, how does david's change in gasoline consumption due to an increase in the price of gasoline depend on his income level? to answer these questions, find the cross-partial derivative, |partial differential^2 g/partial differential m partial differential p_g.
