Economics 101: Winter 2017 UC Davis Sketch Solutions February 28, 2017 PART A: Multiple Choice Questions Each question is worth 3 marks (30 marks in total). MARK YOUR ANSWERS ON YOUR SCANTRON FORM 1. For the years 1948–1973, output per person in the private sector grew 3.3 percent. The growth contribution from labor composition was 0.2 percent, and total factor productivity grew by 2.2 percent. What was the growth contribution from capital per person? (a) 1.5 percent (b) 1.3 percent (c) 3.2 percent (d) 5.3 percent (e) 0.9 percent Answer: (e). The growth accounting decomposition is: growth in output per person = the contribution from capital per person + contribution of labor composition + TFP growth. The answer is therefore: 3 . 3 - 2 . 2 - 0 . 2 = 0 . 9 2. In the Romer model, if an economy’s research share decreases, there will be: (a) an immediate decrease in output and output growth slows (b) an immediate increase in output but output growth slows (c) an immediate increase in output and output growth accelerates (d) an immediate decrease in output but output growth accelerates (e) no change in output but output growth slows. Answer: (b). The fall in the research share means more people to work in final output production. Initially output goes up, but fewer researchers eventually means less innovation and lower growth. 3. Consider the following table and answer this question using the bathtub model of unemployment. Recall that in the bathtub model, U = ¯ s ¯ L ¯ s + ¯ f . Separation rate Finding rate Labor force 2015 2% 20% 130 2016 2.5% 15% 100 In 2015 the natural rate of unemployment is: 1 This study source was downloaded by 100000881534062 from CourseHero.com on 05-19-2024 19:11:29 GMT -05:00 https://www.coursehero.com/file/193350263/MT22017SketchSolutionspdf/
(a) 11.8 (b) 0.2 percent (c) 10.0 percent (d) 90.9 percent (e) 9.1 percent Answer: (e). u = U / ¯ L = (2 / (2 + 20)) = 0 . 091 4. Suppose a college student earns $70,000 per year after graduating and works for 45 years. The interest rate is 2%. What is the present discounted value of their life-time earnings (assuming no growth in wages)? (a) $0.1 million (b) $0.4 million (c) $2.1 million (d) $1.8 million (e) $23 million Answer: (c). PDV = w (1 - ( 1 1+ R ) T ) (1 - ( 1 1+ R )) = 70000 (1 - ( 1 1 . 02 ) 45 ) (1 - ( 1 1 . 02 )) = $2 . 1 million 5. In 2007, the movie Transformers generated about $27.8 million on its opening day. In 1995, Batman Forever generated $20 million on its opening day. The CPI in 2005 was 100, the CPI in 1995 was 78.0, and the CPI in 2007 was 106.2. Which is the larger single-day grossing movie in 2005 dollars? And what was the revenue of this movie in 2005 dollars. (a) Transformers; $27.8 million (b) Transformers; $35.6 million (c) Batman Forever; $35.6 million (d) Batman Forever; $27.8 million (e) Transformers; $26.2 million Answer: (e). Transformers: 27 . 8 / 106 . 2 100 = 26 . 18. Batman: 20 / 78 . 0 100 = 25 . 64. 6. You are the head of the central bank and you want to maintain 2 percent long-run inflation. You use the quantity theory of money. If the real GDP growth is 4 percent and velocity is constant, you suggest a: (a) 6 percent interest rate (b) 6 percent money supply growth (c) 2 percent money supply growth (d) 0 percent money supply growth (e) 2 percent interest rate Answer: (b). From the quantity theory in growth rates: = g m - g y (with constant velocity). 2 = g m - 4 implies g m = 6. 7. During the Great Recession, the US unemployment rate peaked at around: (a) 12.1 percent (b) 25.8 percent (c) 9.5 percent (d) 6.7 percent (e) 10 percent 2 This study source was downloaded by 100000881534062 from CourseHero.com on 05-19-2024 19:11:29 GMT -05:00 https://www.coursehero.com/file/193350263/MT22017SketchSolutionspdf/
Answer: (e) - see Chapter 10 in the textbook for a discussion of the Great Recession. 8. Consider the balance sheet of the following bank: Assets Liabilities Loans 5000 Deposits 6000 Investments 2000 Short Term Debt 500 Reserves and cash 200 What is the leverage ratio? And what the capital ratio? (a) 9.3; 9.7% (b) 10.8; 10.3% (c) 0.1; 10.3% (d) 9.3; 3.3% (e) 14.1; 5.6% Answer: (a). Assets: 7200, Liabilities: 6500, Equity: 700. Leverage ratio: 6500 / 700 = 9 . 3. Capital ratio: 700 / 7200 = 9 . 7 9. If the economy’s natural rate of unemployment is 5 percent and the unemployment rate is 7 percent, according to Okun’s Law what is short-run output? Assume the parameter in this relationship is - 1 / 2, as we studied in class. (a) zero (b) -4 % (c) 4 % (d) -1 % (e) None of the above Answer: (b). Okun’s Law states: u t - ¯ u = - (1 / 2) ˜ Y t , which means (7 - 5) ( - 2) = ˜ Y t = - 4%. 10. At the end of 2009, in the midst of the Great Recession, short run output was -7%. If potential output was approximately $16 trillion, what was actual output at the end of 2009? (a) $17.1 trillion (b) $16.0 trillion (c) $14.9 trillion (d) $15.9 trillion (e) $4.8 trillion Answer: (c). ˜ Y t = Y t - ¯ Y t ¯ Y t = Y t - 16 16 = - 0 . 07. Y t = 14 . 9. 3 This study source was downloaded by 100000881534062 from CourseHero.com on 05-19-2024 19:11:29 GMT -05:00 https://www.coursehero.com/file/193350263/MT22017SketchSolutionspdf/
