The information below applies to a competitive firm that sells its output for $40 per unit. • When the firm produces and sells 150 units of output, its average total cost is $24.50.
• When the firm produces and sells 151 units of output, its average total cost is $24.55.

How does the firm's marginal revenue (MR) compare to its marginal cost (MC) when it increases its output from 150 units to 151 units?
a. MR exceeds MC by $7.95.
b. MR exceeds MC by $11.05.
c. MC exceeds MR by $11.05.
d. MC exceeds MR by $13.50.

Suppose the production function in an economy is y = k0.5l0.5, where k is the amount of capital and l is the amount of labor. the economy begins with 64 units of capital and 16 units of labor. use a calculator and equations in the chapter to find a numerical answer to each of the following questions. what are the wage and the rental price of capital? the wage is equal to unit(s) of output and the rental price of capital is equal to unit(s) of output.

Crowding out is a phenomenon focused upon most by the macroeconomists of whereby a government deficit interest rates, which in turn private investment spending. this group also believed that fiscal policy is the only thing that can lower natural unemployment. is just as effective in countering recessions as monetary policy. can be used most of the time, but monetary policy becomes a better option when velocity is fluctuating. should be used only if the central bank follows a monetary policy rule. faces problematic lags in propagating changes throughout the economy.

Four key marketing decision variables are price (p), advertising (a), transportation (t), and product quality (q). consumer demand (d) is influenced by these variables. the simplest model for describing demand in terms of these variables is: d = k – pp + aa + tt + qq where k, p, a, t, and q are constants. discuss the assumptions of this model. specifically, how does each variable affect demand? how do the variables influence each other? what limitations might this model have? how can it be improved?
