ECON 3123 Exam 1 Study Guide Terms: Economics – the study of how people/society manage(s) their scarce resources; goal is to maximize happiness/utility with what we have available National Income Accounting – the system used to measure GDP and many related statistics National Income Account Identity – Total output = total income = total expenditure; buyers’ expenditure = sellers’ income (shown in circular flow of economic activity diagram) Inputs – resources used for production (resources aren’t always inputs) Endogenous variable – variable that is determined by the model (change causes a move along the curve) Exogenous variable – variable given from outside the model (change causes the curve to shift) Measuring GDP o Product Method – value added summed across industries o Income Method – total factor payments (household income) Y = wL + rK o Expenditure Method – Y = C + I + G + NX **2/3 of GDP is consumption** Consumer Price Index (CPI) – a measure of price level and a good indicator of cost of living; measure of the overall cost of goods and services bought by a typical consumer o Problems with CPI – why it will always overstate the inflation rate (usually by about 1% per year) Substitution bias – when the price of a good goes up, consumers may buy its substitute; however, that good will not be replaced in the fixed market basket Introduction of new goods and services – market basket is fixed in the base year, so goods that weren’t available at that time aren’t included Unmeasured quality changes – linked to intro. of new goods and services Producer Price Index (PPI) – measure of the cost of a basket of goods and services bought by firms Crowding out – fall in private investment due to government borrowing Twin deficit – government budget deficit and trade deficit Study Questions: Q: What are the 6 key variables of macroeconomics? A: Real GDP – adjusted for inflation Inflation – increase in overall price level Unemployment rate – defines business cycle, labor market and short run economy Interest rate – cost of borrowing, opportunity cost of holding money, rate of return Stock Market Exchange rate – real and nominal, international trade Q: What is the primary goal of macroeconomics? A: to explain how economic changes affect many households, firms and markets at the same time Q: Who measures GDP and reports CPI? A: Bureau of Labor Statistics Q: What are the assumptions and implications of the theory of production in the long run? A: factors of production are in fixed supply and are fully employed output will also be fixed Q: What condition determines the amount of labor a firm should hire in order to maximize profit? A: marginal product of labor = real wage Q: What are the assumptions and implications of the theory of distribution in the long run? A: demand for capital and labor are given by marginal product in a competitive market and supply of capital and labor are fixed supply and demand together determine r* and w* Q: Households receive wL and rK (with L and K being fixed); do these payments exhaust national output? A: Yes, because GDP = Y = wL + rK (National Income Account Identity) Q: What makes the S (fixed) curve shift to the right or left? A: taxes, changes in MPC, changes in G & changes in output (because we assumed all these things were fixed in the long run in the national saving equation) Q: What makes the investment curve shift to the right or left? A: investment tax credit from government, uncertainty about future demand & productivity (MP of capital)
