What is the difference between capitalism, socialism, communism • Capitalism: an economic system where most property is privately owned. Private markets are the primary vehicles used to allocate resources and generate incomes • Socialism: Theory that all the means of production should be owned by the community • Communism: State owns and controls the means of production 7. What is the definition of Microeconomics? Macroeconomics? Economics? • Macro: study of the behavior of the economy as a whole • Micro: studies individual prices, quantities and markets CIRCULAR FLOW,NATIONAL INCOME ACCOUNTING AND OTHER MEASUREMENTS 1. 2 Important points of the Circular flow model • GDP can be measured as either a flow of final products or as a flow of earnings or incomes • Leakages (saving, tax, imports) and Injections (investment, exports) 2. What are 4-5 key points in the definition of GDP (i.e., define GDP carefully)? • C+I+G+nx= GDP • Consumption • Investment • Government spending • Net exports 3. 3 Ways to calculate GDP (Value Added is one) • Value added: difference between the value of goods produced and the cost of materials and supplies used in producing them • a flow of final products • a flow of earnings or incomes 4. What is the relation between Gross and Net Investment and Depreciation • Gross investment is everything that remains of total expenditure after consumption government spending and net exports are subtracted. Net investment subtracts depreciation from gross investment. Depreciation: decline in the value of an asset 5. Definition of Real and Nominal GDP • real: quantity of goods and services produced in a nation during a year. Corrects nominal gdp for inflation • nominal: the value, at current market prices, of the total final output produced inside a country during a given year 6. How do you calculate real gdp from nominal? Formula • real GDP= nominal gdp / gdp price index • real=nominal-inflation 7. What is meant by deflating nominal gdp? • Factoring out inflation 8. How do we measure/calculate Unemployment, Labor Force, Employment • Unemployed/ labor force x100= unemployment • Labor force= employed + unemployed • Employment= employment/ civilian non-institutionalized population 9. What are Discouraged Workers and Hidden Unemployment • Discouraged worker= aren’t looking for jobs. • Hidden unemployment= Hidden, or covered, unemployment is the unemployment of potential workers that is not reflected in official unemployment statistics, due to the way the statistics are collected 10.

What is the efficient markets hypothesis, and how does it relate to random walks? • Efficient market hypothesis: market prices contain all available information. It is not possible to make profits by acting on old information or at patterns of past price changes. Random walks: movements over time are completely unpredictable • In an efficient market, all predictable things have already been built into the prices; efficient market theory explains why stock prices look so erratic. Stock prices move in response to erratic events so prices do also. 11. What are Bonds? Bond Ratings, Junk Bonds, Treasury Bonds, Corporate Bonds, Muni/S&L Bonds? • Bond: certificate of indebtedness • Bond ratings: A grade given to bonds that indicates their credit quality • Junk Bonds: high yield high risk bonds • Treasury Bond: A government bond issued by the US Treasury • Corporate Bond: a bond issued by a corporation; carries no claim to ownership and pays no dividends but payments to bondholders have priority over payments to stockholders • Municipal Bond: A security issued by or on behalf of a local authority. 12.

What are the condition(s) for equilibrium? • aggregate D = Agg S=y • unintended inventories=0 • planned=actual investment • desired leakages=desired investment (without G,T,NX) -> I=S (or I=S+(T-G)+(M-X) • Agg D = y 7. What is the role of inventories? • 8. What factors shift the aggregate demand curve? The aggregate supply curve? • Exogenous changes in C+I+G+X-M, monetary and fiscal policy 9.
