Average Variable Cost
Total variable costs divided by the number of units of output.
Marginal Cost
The increase in total cost that arises from an extra unit of production, the increase or decrease in costs as a result of one more or one less unit of output
Law of Diminishing Return
When additonal units of a variable input are added to fixed inputs after a certain point, the marginal product of the variable input declines.

Aggregate Supply
The total amount of goods and services in the economy available at all possible price levels
Keynesian Economics
Theory stating that government spending should increase during business slumps and be curbed during booms, economics argues that private sector decisions sometimes lead to inefficient macroeconomic outcomes and therefore, advocates active policy responses by the public sector, including monetary policy actions by the central bank and fiscal policy actions by the government to stabilize output over the business cycle.
Money Demand
A relationship between the interest rate and the quantity of money that people are willing to hold at any given interest rate.
Money Supply
The quantity of money available in the economy
Federal Reserve System
The country's central banking system, which is responsible for the nation's monetary policy by regulating the supply of money and interest rates
Money Multiplier
The amount of money the banking system generates with each dollar of reserves, the multiple by which deposits can increase for every dollar increase in reserves; equal to 1 divided by the required reserve ratio.
An increase in the overall level of prices in the economy
A period of slow economic growth and high unemployment while prices rise (inflation)
The state of the economy declines, A period of an economic contraction, sometimes limited in scope or duration.
Automatic Stablizers
Taxes and transfer payments, Federal government expenditures or receipts that automatically increase or decrease without requiring action by Congress or the President. Examples are unemployment compensation and corporate and individual income tax.
Trade Restrictions
Tariffs and quotas restrict the amount of a good imported and supply will decrease
Captial Account
The net result of public and private international investments flowing in and out of a country. The net results includes foreign direct investment, plus changes in holdings of stocks, bonds, loans, bank accounts, and currencies.
Long Run Phillips Curve
Relationship between the inflation rate and the unemployment rate in the long run, looks at long-term natural rate of unemployment.
Equilbrium Exchange Rate
Exchange rate at which demand for a currency is equal to the supply of the currency in the economy.
Price Level
An index that traces the relative changes in the price of an individual good (or a market basket of goods) over time
Protectionist Policy
A way to "protect" or insulate a domestic industry from competition by foreign producers of the same good. import tariff allows domestic producers to both capture a larger share of the domestic market and charge a higher price than would otherwise be possible
Comparative Advantage
The ability of an individual, firm, or country to produce a good or service at a lower opportunity cost than other producers.
Absolute Advantage
The ability of an individual, firm, or country to produce more of a good or service than competitors using the same amount of resources.

Are maximum prices set by the government for particular goods and services that they believe are being sold at too high of a price and thus consumers need some help purchasing them.
Diseconomies Of Scale
An economic concept referring to a situation in which economies of scale no longer function for a firm. Rather than experiencing continued decreasing costs per increase in output, firms see an increase in marginal cost when output is increased.
Economies of Scale
The increase in efficiency of production as the number of goods being produced increases.
Growth Rate
Is the percentage increase or decrease of GDP from the previous measurement cycle. It is annualized so it can be compared to the previous year.

Trade Quotas
Restritions to free trade, put a legal limit on the amount that can be imported, creating shortages which cause prices to rise.
Taxes on imports, raise the price of imported goods, which increases the demand and price for the same goods produced by domestic suppliers. Revenues from these are collected by the domestic government.
Prohibit trade with other nations. They bar a foreign nation's imports or ban exports to that nation or both.
