Imagine that someone offers you $100 today or $200 in 10 years. You would prefer to take the $100 today if the interest rate is Group of answer choices 4 percent. 6 percent. 8 percent. All of the above are correct.

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.
