T/F -Variance is a measure of the variability of returns, and since it involves squaring the deviation of each actual return from the expected return, it is always larger than its square root, the standard deviation. -If an investor owns two stocks, one whose standard deviation is 0.21 and the other whose standard deviation is 0.10, the required return could be higher on the stock with the lower standard deviation. -Different investors have different degrees of risk aversion but this...

Given ACi = f (qi, w, v, t) where t is technology and technology is cost-reducing, as t increases: A) What will be the long run effect on market price, P, and quantity, Q, and the number of firms in the industry, N, if it is a constant cost industry. Draw a graph of the long run supply and demand. On what will the size of the change in Q depend? B) If this is an increasing cost industry, how...

T/F The variance of an asset's return can be less than the standard deviation of that asset's return. If an investor owns two stocks, one whose standard deviation is 0.21 and the other whose standard deviation is 0.10, the required return will be higher for the stock with the higher standard deviation. Different investors have different degrees of risk aversion, and the result is that investors with greater risk aversion tend to hold securities with lower risk (and therefore a...

6.(a) Show that if f : [a,b]→R is Riemann integrable and if m ≤ f (t) ≤ M holds for all t in the subinterval [c,d] of [a,b], then m(d −c) ≤ ∫cd f(t) dt ≤ M(d −c). (that is supposed to be f integrated from c to d) (b) Prove the fundamental theorem of calculus, in the form given in the Introduction to this book. (Hint: Use part (a) to estimate F(x)−F(x0)/x−x0.)
