The Circular Flow and GDP - AP Macroeconomics

1. State the formula for the income approach to GDP.

   $GDP = Wages + Rent + Interest + Profit$. Sums all factor payments earned in production.

2. What does the 'I' represent in the GDP formula?

   Investment. Business spending on capital goods and inventory.

3. Define the circular flow of income.

   A model that shows how money flows through the economy between households and firms. Shows economic interdependence through spending and income flows.

4. What role do firms play in the circular flow model?

   Firms produce goods and services and pay for factors of production. Supply goods and demand factors of production.

5. State the formula for the GDP deflator.

   $GDP\ Deflator = \frac{Nominal\ GDP}{Real\ GDP} \times 100$ . Ratio showing price level changes over time.

6. Identify a limitation of GDP as a measure of economic performance.

   GDP does not account for the distribution of income. GDP ignores inequality and non-market activities.

7. Identify the leakages in the circular flow model.

   Savings, Taxes, Imports. Money flows that exit the circular flow system.

8. What is the role of government in the circular flow model?

   Collects taxes and provides public goods and services. Government participates through spending and taxation flows.

9. What is the difference between total GDP and GDP per capita?

   Total GDP measures total output; GDP per capita measures output per person. Per capita adjusts for population differences between countries.

10. State the formula for calculating net exports.

    $Net\ Exports = Exports - Imports$. Measures trade balance in GDP calculations.

11. What is the income approach to GDP?

    Calculating GDP by summing all incomes earned in the economy. Measures GDP through factor payments to households.

12. Identify the injections in the circular flow model.

    Investment, Government Spending, Exports. Money flows that enter the circular flow system.

13. What do 'X' and 'M' represent in the GDP formula?

    X = Exports, M = Imports. Trade components where net exports equals $X - M$.

14. What is depreciation in the context of GDP?

    The decrease in value of capital assets over time. Capital consumption that reduces productive capacity.

15. What does the 'G' represent in the GDP formula?

    Government Spending. Public sector purchases of goods and services.

16. What is the production approach to GDP?

    Calculating GDP by summing the value added at each stage of production. Measures GDP through value creation at each production stage.

17. What is a transfer payment?

    A payment for which no goods or services are exchanged, not included in GDP. Redistributes income without creating new production.

18. Define GDP.

    The total market value of all final goods and services produced within a country in a year. Measures total economic output using market prices for final goods only.

19. What is GDP per capita?

    GDP divided by the population of a country. Measures average economic output per person.

20. What role do households play in the circular flow model?

    Households provide factors of production and consume goods and services. Supply labor and demand goods in the circular flow.

21. What are the four components of GDP?

    Consumption, Investment, Government Spending, Net Exports. The four spending categories that sum to total GDP.

22. What is double counting in GDP calculation?

    Counting intermediate goods more than once in GDP. Including intermediate goods inflates GDP measurement incorrectly.

23. What does GNP stand for?

    Gross National Product. Measures total national production regardless of location.

24. What does the 'C' represent in the GDP formula?

    Consumption. Household spending on goods and services.

25. What is the role of financial markets in the circular flow?

    Channel savings into investments. Connect savers with borrowers for investment funding.

26. What is the purpose of the GDP deflator?

    To adjust nominal GDP for inflation. Removes inflation to show real economic growth.

27. Identify the primary sectors in the circular flow model.

    Households, Firms, Government, Financial Markets, Foreign Sector. All economic agents participating in circular flow.

28. What is the GDP deflator?

    A measure that converts nominal GDP into real GDP. Price index that removes inflation effects from nominal GDP.

29. What does the product market do in the circular flow model?

    Where goods and services are bought and sold. Where firms sell output and households buy goods.

30. What does GDP stand for?

    Gross Domestic Product. Standard acronym for measuring total economic output.

31. What is the difference between nominal and real GDP?

    Nominal GDP is not adjusted for inflation; real GDP is adjusted for inflation. Real GDP removes price level changes to show actual output changes.

32. What is the formula for GDP using the expenditure approach?

    $GDP = C + I + G + (X - M)$. Standard expenditure method where net exports equals exports minus imports.

33. What is the black market's impact on GDP measurement?

    Black market activity is not included in GDP. Underground activities escape official measurement systems.

34. What is an open economy?

    An economy that engages in international trade. Includes foreign sector through imports and exports.

35. What is the difference between GNP and GDP?

    GNP includes income from abroad; GDP does not. GNP measures national income regardless of location.

36. What does the factor market do in the circular flow model?

    Where factors of production are bought and sold. Where households sell labor and firms buy inputs.

37. What is the underground economy?

    Economic activity not reported to the government and not included in GDP. Hidden economic activity that avoids taxation and regulation.

38. What is the purpose of national income accounting?

    To measure economic activity and performance. Systematic recording of economic transactions and output.

39. What is a closed economy?

    An economy with no international trade. No foreign sector involvement in economic activity.

40. What is the significance of the base year in GDP calculation?
