13445212236GDP = C + I + G + XnThe expenditure approach to measuring GD correlates well with aggregate demand (AD)11
13445212239GDP DeflatorA price index used to adjust nominal GDP to arrive at real GDP. Called the "deflator" because nominal GDP will usually overstate the value of a nation's output if there has been inflation. The Consumer Price Index (CPI) is another commonly used price index.12
13445212240GDP Growth Rate:( Current year's GDP - Last year's GDP)/ (Last year's GDP) x 100. The GDP growth rate is a percentage change in a nation's real output between one year and the next.13
13445212241The Inflation Rate via the CPI(This year's CPI - Last year's CPI)/(Last year's CPI) x 100. The inflation rate is the percentage change in the CPI from one period to the next.14
13445212242Real Interest Ratethe interest rate corrected for the effects of inflation; Nominal interest rate - inflation rate15
13445212243Unemployment Rate(Number of unemployed/Number in the labor force) x 100. The labor force includes all non-institutionalized people of working age who are employed or seeking employment.16
13445212244Money Multiplier1/RR where RR equals the required reserve ratio. Application: an initial injection of $1,000 of new money into a banking system with a reserve ratio of 0.1 will generate up to $1,000 x (10) = $10,000 in total money.17
13445212245Quantity Theory Of MoneyMV = PQ = Y. A monetarist's view that explains how changes in the money supply (M) will affect the price level (P) and/or real output assuming the velocity of money (V) is fixed in the short run.18
13445212246MPC + MPS = 1The fraction of an increase in disposable income that is spent (MPC) plus the fraction that is saved (MPS) must equal 1.19
13445212247Spending Multiplier= 1/(1-MPC) or 1/MPS. This tells you how much total spending an initial interjection of spending in the economy will generate. For example, if the MPC = .8 and the government spends $100 million, then the total increase in spending in the economy = $100 x 5 = $500 million.20
13445212248Tax Multiplier = (-MPC)/MPSThis tells you how much total spending will result from an initial change in the level of taxation. It is negative because when taxes decrease, spending increases, and vice versa. The tax multiplier will always be smaller than the spending multiplier.21
13445212249Absolute AdvantageA country or individual has an absolute advantage in the production of a good when the country can produce the good using fewer resources (inputs) than another country or individual.22
13445212250AppreciationAn increase in the value of one currency relative to another, resulting from an increase in demand for or a decrease in supply of the currency on the foreign exchange market.23

13445212255Capital Account (AKA Financial Account)Measures the flow of funds for investment in real assets (such as factories or office buildings) or financial assets (such as stocks and bonds) between a nation and the rest of the world.28
13445212257Circular Flow DiagramA model of the macroeconomy that shows the interconnectedness of businesses, households, government, banks, and the foreign sectors. Money flows in a circular direction, and goods, services, and resources flow in the opposite circular direction.29
13445212258Classical Economic TheoryThe view that an economy will self-correct from periods of economic shock if left alone. AKA "laissez-faire"30
13445212259Comparative AdvantageWhen an individual, a firm, or a nation is able to produce a particular product at a lower opportunity cost than another individual, firm, or nation. Comparative advantage is the basis on which nations trade with one another.31
13445212260Consumer Price Index (CPI)An index that measures the price of a fixed market basket of consumer goods bought by a typical consumer. The CPI is used to calculate the inflation rate in a nation.32
13445212261Consumption.A component of a nation's aggregate demand; measures the total spending by domestic households of goods and services.33
13445212262Contractionary Fiscal PolicyA policy whereby government increases taxes or decreases its spending in order to reduce aggregate demand. Could be used in a period of high inflation to bring down the inflation rate.34
13445212263Contractionary Monetary PolicyA demand-side policy whereby the central bank 1. Increases reserve requirments 2. Decreases discount rate 3. Sells bonds on the open market35
13445212264Cost-Push InflationInflation resulting from a decrease in AS (from higher wage rates and raw material prices, such as the price of oil) and accompanied by a decrease in real output and employment. Also reffered to as "stagflation" or "adverse aggregate supply shock".36
13445212265Crowding-Out EffectThe rise in interest rates and the resulting decrease in investment spending in the economy caused by increased government borrowing in the loanable funds market. Seen as a disadvantageous side effect of expansionary fiscal policy.37
13445212266Current AccountMeasures the balance of trade in goods and services and the flow on income between one nation and all other nations. It also records monetary gifts or grants that flow into or out of a country. Equal to a country's net exports (its exports minus its imports).38
13445212267Cyclical UnemploymentUnemployment caused by a fall in aggregate demand in a nation. Not included in the natural rate of unemployment. When a nation is in a recession, there will be cyclical unemployment.39

13445212273Economic ResourcesLand, labor, capital, and entrepreneurial ability that are used in the production of goods and services. They are "economic" resources because they are scarce (limited in supply and desired). Also known as "factors of production".45
13445212274Excess ReservesThe amount by which a bank's actual reserves exceed its required reserves. Banks can lend excess reserves; when they do, they expand the money supply. The amount of excess reserves in the banking system determines equilibrium interest rate.46
13445212275Exchange Rate:The price of one currency in terms of another currency, determined in the forex market.47
13445212276ExportsThe spending by foreigners on domestically produced goods and services. Counts as an injection into a nation's circular flow of income.48
13445212277Federal Funds RateThe interest rate banks charge one another on overnight loans made out of their excess reserves. The FFR is the interest rate targeted by the FEd through it's open market operations.49

13445212286InflationA rise in the average level of prices in the economy over time (percentage change in the CPI)57
13445212288Interest RateThe opportunity cost of money. Either the cost of borrowing money or the cost of spending money (e.g., the interest rate is what would be given up by not saving money). Conversely, this is the price a lender is paid for allowing someone else to use money for time.58
13445212289InvestmentA component of aggregate demand, it includes all spending on capital equipment, inventories, and technology by firms. This does not include financial investment, which is the purchase of financial assets (stocks and bonds). Also includes household purchasing of newly constructed residences.59
13445212290Law of Increased Opportunity CostAs more of particular product is produced, the opportunity cost, in terms o what must be given up of other goods to produce each unit of the product, increases. Explains the convex shape of a nation's production possibilities curve.60
13445212291Loanable Funds MarketThe market in which the demand for private investment and the supply of household savings intersect to determine the equilibrium real interest rate.61

13445212304MoneyAny object that can be used to facilitate the exchange of goods and services in a market.70
13445212305Money DemandThe sum of the transaction demand and the asset demand for money. Inversely related to the nominal interest rate.71
13445212306Money MarketThe market where the supply of money is set by the central bank; includes the downward sloping money-demand curve and a vertical money-supply curve. The "price" of money is the nominal interest rate.72

13445212308Multiplier EffectThe increase in total spending in an economy resulting from an initial interjection of new spending. The size of the multiplier effect depends upon the spending multiplier.74
13445212309Natural Rate Of Unemployment (NRU)The level of unemployment that prevails in an economy that is producing at a full employment level of output. Includes structural and frictional unemployment. While countries NRUs can vary, the NRUs in the US tend to be close to 5 percent.75
13445212311Open-Market OperationsThe central bank's buying and selling of government bonds on the open market from commercial banks and the public. This is aimed at increasing or decreasing the level of reserves in the banking system and thereby affects the interest rate and the level of aggregate demand.76
13445212312Opportunity CostWhat must be given up to have anything else. Opportunity costs are not neccesarily monetary costs, but rather include what you could do with the resources you use to undertake any activity or exchange.77

13445212318Rational Expectations TheoryThe hypothesis that business firms and househlds expect monetary and fiscal policies to have certain effects on the economy and take, in pursuit of their own self interests, actions which make these policies ineffective at changing real output.83
13445212319RecessionA contraction in total output of goods and services in a nation between two periods of time. Could be caused by a decrease in aggregate demand or in aggregate supply.84
13445212320Recessionary GapThe difference between an economy's equilibrium level of output and its full employment level of output when an economy is in a recession.85
13445212321Self-CorrectionThe idea that an economy producing at an equilibrium level of output that is below or above its full employment will return on its own to its full employment level left to its own devices. Requires flexible wages and prices and is associated with classical economic views.86
13445212322StagflationA macroeconomic situation in which both inflation and unemployment increase. Caused by a negative supply shock.87
13445212323Sticky Wage and Price ModelThe short run Aggregate-Supply Curve is sometimes referred to as the "sticky wage and price model", because worker's wage demands take time to adjust to changes in the overall price level, and therefore, in the short run an economy may produce well below or beyond its full employment level of output.88
13445212324Structural UnemploymentUnemployment caused by changes in the structure of demand for goods and in technology; workers who are unemployed because they do not match what is in demand by producers in the economy or whose skills have been left behind by economic advancement89
13445212325Supply ShockAnything that leads to a sudden, unexpected change in aggregate supply. Can be negative (decreases AS) or positive (increases AS). May include a change in energy prices, wages, or business taxes, or may result from a natural disaster or a new discovery of important resources.90
13445212326Trade DeficitWhen a country's total spending on imported goods and services exceeds its total revenues from the sale of exports to the rest of the world. Synonymous with a surplus in the current account of the balance of the payments and with a negative net export component of the GDP.91
13445212327Trade SurplusWhen a country's sale of exports exceeds its spending on imports. Synonymous with a surplus in the current account of the balance of payments.92

13445212335expansionary fiscal policyenacted when the government deliberately increases its deficit to stimulate the economy; the government increases its spending (increases G), cuts taxes (decreases T), or both, and stimulates the economy by expanding aggregate demand (AD).97
13445212336expansionary monetary policymonetary policy methods by which the Fed aims to increase the money supply and lower interest rates, thereby creating an increase in output; in pursuit of expansionary policy goals, the Fed can lower the required reserve ratio, lower the discount rate, or purchase government securities on the open market.98
13445212337expenditure approacha way of measuring the GDP by adding up all spending on final goods and services during a given year.99
13445212339hyperinflationa very high rate of inflation, under which prices go up very rapidly, often more than 1,000 percent in a year. This causes money to become a poor store of value.100
