A $1,000 par value bond sells for $1,216. It matures in 20 years, has a 14 percent coupon, pays interest semiannually, and can be called in 5 years at a price of $1,100. The bond's yield to maturity is: (Round the answer to two decimal places.)

In the short-run, marginal costs are equal to the change in variable costs as output changes. ( mc = change in variable cost / change in quantity) assume that capital is fixed in the short-run. (a) start with the equation for marginal cost and derive an equation that relates marginal cost of production to the cost and productivity of labor. (b) draw a standard looking short-run marginal cost curve and use the equation you derived to explain its shape.
