Long-run average cost is based on economies of scale (or increasing returns to scale) and diseconomies of scale (or decreasing returns to scale).

The Fed is responsible for ensuring that the economy has the proper amount of money in circulation.- In the old days, governments controlled the money supply by printing and minting money.
- In modern times, with bank checkable deposits in the money supply, the Fed controls money by controlling banks.
Two reasons: - First: Too much money causes inflation and too little money leads to recession and unemployment. The challenge is to keep enough money in circulation.
- Second: Money is absolutely essential in a modern complex economy. Faith in the value of fiat money is best provided by a centralized, national government that has the authority to ensure the value of money.

MARGINAL REVENUE CURVE, MONOPOLISTIC COMPETITION A curve that graphically represents the relation between the marginal revenue received by a monopolistically competitive firm for selling its output and the quantity of output sold. Because a monopolistically competitive firm is a price maker and faces a negatively-sloped demand curve, its marginal revenue curve is also negatively sloped and lies below its average revenue (and demand) curve. A monopolistically competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.
