The small and isolated island of Bithaca has no contact with the outside world. Only two firms operate in this economy: Joe & Bros. Farm which produces wheat, and Big Bakery, which makes bread (the only final product in the economy) using the wheat provided by Joe & Bros. Farm. The following data are given for the year 2005. Joe & Bros. ($) Total output Total Expenses Wages Rent & Interest Intermediate Goods Purchased 50,000 Big Bakery ($) 150,000 27,000 4,000 0 51,500 9,000 ? a) Answer the following questions: i.What is the value of the intermediate goods purchased by Big Bakery? ii.What is the value added to GDP by Joe & Bros.? iii.What is the value added to GDP by Big Bakery? iv.What is the GDP for Bithaca? Show your calculations. v.What is the GNP for Bithaca? Show your calculations. b) Assume that although Big Bakery produces $150,000 worth of bread it is only able to sell $125,000. The remaining $25,000 thousands worth of bread is stored. What is the GDP of Bithaca now? 8. Suppose the following data apply to the United States for the year 2004 (all figures are in billion of dollars). (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) Depreciation Personal consumption expenditures Rental income Government expenditures on goods and services Net interest Compensation of employees Proprietors’ Income Indirect taxes less subsidies Corporate profits Gross private investment Net exports Net factor payments to the rest of the world 1,500 8,231 163 2,183 546 6,765 946 803 1,118 1,922 -609 -114 Assume that all income and expenditure data not listed above is equal to zero. a) Compute gross domestic product (GDP) using the expenditure approach. Show what numbers you used. b) Compute gross domestic product (GDP) using the income approach. Show what numbers you used. 2 9. Freestone is an isolated community that produces only three final goods: pizza, notebooks, and tonic water. Information on population, nominal prices and total output for each good in the years 1980 and 2004 is given below. pizza notebooks tonic water (bottle) 1980 per unit Price Output ($’s) (in millions) 1.00 1 4.00 4 1.50 2 2004 per unit Price Output ($’s) (in millions) 2.75 3 7.00 10 2.50 4 NOTE: THE POPULATION IN 1980 IS 10,000 AND IN 2004 IS 15,000 a) Calculate nominal GDP for 1980. b) Calculate nominal GDP for 2004. c) Calculate real GDP for 1980 and 2004 if the BASE YEAR is 1980. d) Has the standard of living increased or decreased since 1980? HINT: compare real GDPs per capita. e) Calculate real GDP for 1980 and 2004 if the BASE YEAR is 2004. f) What is the implicit GDP deflator for 1980 and for 2004? (Use 1980 as the base year.) g) By what percent has the price level increased between 1980 and 2004? (Use GDP deflators from part f as price indices). h) Assume that the base year is 1980 and in the basket purchased by the representative consumer is one pizza and one bottle of tonic water. What is CPI for 1980? What is CPI for 2004? What is an average annual rate of inflation? (Hint: to get the average annual rate of inflation just divide the overall percentage price change from 1980 to 2004 by 24 years). 3
