ECO 55O MIDTERM EXAM PART 1 LATEST NOTE: TWO VERSIONS POSTED Version 1 Question 1 In the shareholder wealth maximization model, the value of a firm's stock is equal to the present value of all expected future ____ discounted at the stockholders' required rate of return. Answer profits (cash flows) revenues outlays costs investments Question 2 The flat-screen plasma TVs are selling extremely well. The originators of this technology are earning higher profits. What theory of profit best reflects the performance of the plasma screen makers? Answer risk-bearing theory of profit dynamic equilibrium theory of profit innovation theory of profit managerial efficiency theory of profit stochastic optimization theory of profit Question 3 Income tax payments are an example of ____. Answer implicit costs explicit costs normal return on investment shareholder wealth Question 4 The Saturn Corporation (once a division of GM) was permanently closed in 2009. What went wrong with Saturn? Answer Saturn’s cars sold at prices higher than rivals Honda or Toyota, so they could not sell many cars. Saturn sold cars below the prices of Honda or Toyota, earning a low 3% rate of return. Saturn found that young buyers of Saturn automobiles were very loyal to Saturn and GM. Saturn implemented a change management view that helped make first time Saturn purchasers trade up to Buick or Cadillac. Question 5 Recently, the American Medical Association changed its recommendations on the frequency of pap-smear exams for women. The new frequency recommendation was designed to address the family histories of the patients. The optimal frequency should be where the marginal benefit of an additional pap-test: Answer equals zero. is greater than the marginal cost of the test is lower than the marginal cost of an additional test equals the marginal cost of the test Question 6 To reduce Agency Problems, executive compensation should be designed to: Answer create incentives so that managers act like owners of the firm. avoid making the executives own shares in the company. be an increasing function of the firm's expenses. be an increasing function of the sales revenue received by the firm. Question 7 The standard deviation is appropriate to compare the risk between two investments only if Answer the expected returns from the investments are approximately equal the investments have similar life spans objective estimates of each possible outcome is available the coefficient of variation is equal to 1.0 Question 8 The approximate probability of a value occurring that is greater than one standard deviation from the mean is approximately (assuming a normal distribution) Answer 68.26% 2.28% 34% 15.87% Question 9 The ____ is the ratio of ____ to the ____. Answer standard deviation; covariance; expected value coefficient of variation; expected value; standard deviation correlation coefficient; standard deviation; expected value coefficient of variation; standard deviation; expected value Question 10 Based on risk-return tradeoffs observable in the financial marketplace, which of the following securities would you expect to offer higher expected returns than corporate bonds? Answer U.S. Government bonds municipal bonds common stock commercial paper Question 11 An closest example of a risk-free security is Answer General Motors bonds AT&T commercial paper U.S. Government Treasury bills San Francisco municipal bonds an I.O.U. that your cousin promises to pay you $100 in 3 months Question 12 The primary difference(s) between the standard deviation and the coefficient of variation as measures of risk are: Answer the coefficient of variation is easier to compute the standard deviation is a measure of relative risk whereas the coefficient of variation is a measure of absolute risk the coefficient of variation is a measure of relative risk whereas the standard deviation is a measure of absolute risk the standard deviation is rarely used in practice whereas the coefficient of variation is widely used Question 13 An income elasticity (Ey) of 2.0 indicates that for a ____ increase in income, ____ will increase by ____. Answer one percent; quantity supplied; two units one unit; quantity supplied; two units one percent; quantity demanded; two percent one unit; quantity demanded; two units ten percent; quantity supplied; two percent Question 14 When demand elasticity is ____ in absolute value (or ____), an increase in price will result in a(n) ____ in total revenues. Answer less than 1; elastic; increase more than 1; inelastic; decrease less than 1; elastic; decrease less than 1; inelastic; increase Question 15 Those goods having a calculated income elasticity that is negative are called: Answer producers' goods durable goods inferior goods nondurable goods Question 16 Suppose we estimate that the demand elasticity for fine leather jackets is .7 at their current prices. Then we know that: Answer a 1% increase in price reduces quantity sold by .7%. no one wants to buy leather jackets. demand for leather jackets is elastic. a cut in the prices will increase total revenue. leather jackets are luxury items. Question 17 Auto dealers slash prices at the end of the model year in response to deficient demand/excess inventory but restaurants facing the same problem slash production because Answer auto customers are less price sensitive than restaurant customers price elasticity of demand (in absolute values) is higher for auto than restaurant customers price elasticity of supply is lower in auto than in restaurants restaurant food spoils quickly and is much more perishable price elasticity of supply in autos is smaller than the absolute value of price elasticity of demand but the reverse is true for restaurants Question 18 If demand were inelastic, then we should immediately: Answer cut the price. keep the price where it is. go to the Nobel Prize Committee to show we were the first to find an upward sloping demand curve. stop selling it since it is inelastic. raise the price Question 19 Marginal revenue (MR) is ____ when total revenue is maximized. Answer greater than one equal to one less than zero equal to zero equal to minus one Question 20 The constant or intercept term in a statistical demand study represents the quantity demanded when all independent variables are equal to: Answer 1.0 their minimum values their average values 0.0 Question 21 The standard deviation of the error terms in an estimated regression equation is known as: Answer coefficient of determination correlation coefficient Durbin-Watson statistic standard error of the estimate Question 22 In regression analysis, the existence of a significant pattern in successive values of the error term constitutes: Answer heteroscedasticity autocorrelation multicollinearity nonlinearities a simultaneous equation relationship Question 23 All of the following are reasons why an association relationship may not imply a causal relationship except: Answer the association may be due to pure chance the association may be the result of the influence of a third common factor both variables may be the cause and the effect at the same time the association may be hypothetical Question 24 In testing whether each individual independent variables (Xs) in a multiple regression equation is statistically significant in explaining the dependent variable (Y), one uses the: Answer F-test Durbin-Watson test t-test z-test Question 25 In which of the following econometric problems do we find Durbin-Watson statistic being far away from 2.0?
