Let Kt denote the quantity of capital a country has at the beginning of period t. Also, suppose that capital depreciates at a constant rate d, so that dKt of the capital stock wears out during period t. If investment during period t is denoted by It, and the country does not trade with the rest of the world (the current account surplus is always zero), then we can say that the quantity of capital at the beginning of period t + 1 is given byKt+1 = (1 - d)Kt + ItSuppose at the beginning of year 0 that this country has 80 units of capital. Investment expenditures are 10 units in each of years 0, 1, 2, 3, 4, . . . , 10. The capital stock depreciates by 10% per year.(a) Calculate the quantity of capital at the beginning of years 0, 1, 2, 3, 4, . . . , 10.(b) Repeat part (a), except assume now that the country begins year 0 with 100 units of capital. Explain what happens now, and discuss your results in parts (a) and (b).

Alandowner and his neighbor purchased adjoining undeveloped lots. after both built homes on their respective lots, the landowner suggested to the neighbor that a common driveway be built where the two lots joined. the neighbor agreed. the landowner and the neighbor split the cost of constructing the driveway and entered into a written agreement to equally share the costs of its upkeep and maintenance. the agreement was recorded in the county recorder's office. two years later, the neighbor built a new driveway located entirely on his lot. the common driveway, which the landowner continued to use but which the neighbor no longer used, began to deteriorate. the landowner asked the neighbor for money to maintain the common driveway, but the neighbor refused to contribute. three years later, the neighbor conveyed his lot to a friend. the friend entered into possession and used only the driveway built by the neighbor. by this time, the common driveway had deteriorated badly and contained numerous potholes. the landowner asked the friend to pay half of what it would take to repair the common driveway. the friend refused. the landowner repaired the driveway and sued the friend for 50% of the cost of repairs. will the landowner prevail?

There are three factors that can affect the shape of the treasury yield curve (r* t , ip t , and mrp t ) and five factors that can affect the shape of the corporate yield curve (r* t , ip t , mrp t , drp t , and lp t ). the yield curve reflects the aggregation of the impacts from these factors. suppose the real risk-free rate and inflation rate are expected to remain at their current levels throughout the foreseeable future. consider all factors that affect the yield curve. then identify which of the following shapes that the us treasury yield curve can take. check all that apply.a. downward-sloping yield curveb. upward-sloping yield curvec. inverted yield curve

Which of the following statements is correct? stockholders should generally be happier than bondholders to have managers invest in risky projects with high potential returns as opposed to safe projects with lower expected returns. potential conflicts between stockholders and bondholders are increased if a firm's bonds are convertible into its common stock. takeovers are most likely to be attempted if the target firm’s stock price is above its intrinsic value. one advantage of operating a business as a corporation is that stockholders can deduct their pro rata share of the taxes the firm pays, thereby eliminating the double taxation investors would face in a partnership.
