B) the idea that the standard pattern of contraction—trough—expansion—peak occurs again and again in industrial economies. C) the tendency of many economic variables to move together in a predictable way over the business cycle. D) the idea that peaks and troughs of the business cycle occur at regular intervals. Answer: A 22) The idea that the business cycle is recurrent means that A) declines in economic activity tend to be followed by further declines, and growth in economic activity tends to be followed by more growth. B) the standard pattern of contraction—trough—expansion—peak occurs again and again in industrial economies. C) many economic variables to move together in a predictable way over the business cycle. D) peaks and troughs of the business cycle occur at regular intervals. Answer: B 23) Define the following characteristics of business cycles: recurrence and persistence. Answer: Business cycles exhibit recurrence and persistence: (1) Recurrence means that each complete cycle is followed by another complete cycle. (2) Persistence means that, once begun, each contraction tends to continue. Likewise, once begun, each expansion tends to continue. For example, the contraction lasted for 16 months, and the expansion lasted for 93 months. These are persistent events. 24) Describe the major features of the business cycle. Be sure to discuss what variables are affected by the cycle, a description of the key features that are apparent in the data, how variables are related to one another, how regular the cycle is, and how predictable the cycle is. Answer: The business cycle is defined as a fluctuation of aggregate economic activity. There are recurrent but not periodic movements of aggregate activity, with many variables moving in the same direction at the same time (comovement). Increases in aggregate economic activity are expansions, while reductions in aggregate economic activity are contractions, or recessions. Both expansions and contractions exhibit persistence, so once an expansion or contraction begins, it tends to last some time. 25) When a recession occurs, do economists expect it to be a temporary phenomenon? Or is there some degree of permanence? What is the empirical evidence? Answer: Recent research suggests that recessions may contain permanent components. Some economists argue that only the recession led to a permanent change in the U.S. economy, because it changed the economy's use of oil permanently. Other studies suggest that perhaps 30% of changes in real output are permanent and 70% are temporary for the postwar United States. 8.2 1) The longest contraction in American history occurred A) during the 1870s.

B) misuse of historical data had caused economists to understate the size of cyclical fluctuations in the post-World War II era. C) economists had ignored the roles of the government and international trade in mitigating economic fluctuations prior to World War II. D) economists had left out important components of GDP, such as wholesale and retail distribution, transportation, and services, in their pre-World War II estimates. Answer: D 13) Christina Romer argued that A) measured properly, GNP before 1929 varied substantially less over time than the official statistics showed. B) measured properly, GNP after 1929 varied substantially more over time than the official statistics showed. C) measured properly, economic expansions after 1929 were shorter than the official statistics showed. D)measured properly, economic expansions before 1929 were shorter than the official statistics showed. Answer: A 18) Stock and Watson found that monetary policy was responsible for about ________% of the reduction in output volatility that occurred in the mid-1980s. A) 0 to 10 B) 10 to 20 C) 20 to 30 D) 30 to 40 Answer: C 19) Stock and Watson found that ________ was responsible for about 20—30 % of the reduction in output volatility that occurred in the mid-1980s. A) reduced shocks to productivity B) reduced shocks to food and commodity prices C) better monetary policy D) better inventory control Answer: C 20) The widespread decline in the volatility of many macroeconomic variables after 1984 led economists to term this period the A) Great Moderation. B) Low Volatility Era. C) Steady State. D) Long Boom. Answer: A 21) How has the severity and duration of business cycles changed over time in the United States? Answer: Though it is a controversial subject, it appears that business cycles have become less severe over time. Recessions have certainly been shorter since World War II than they were before 1929. There is some disagreement about how severe they were before 1929, with Christina Romer arguing that measurement problems in the old data misled economists about how severe those recessions were. But others find that the old data is just about right and conclude that the business cycle is much less severe today. 22) If you were a member of the NBER business-cycle dating committee, would you declare that the U.S. economy is now in a recession? Why? Describe the major variables that you would look at to determine whether the economy is in a recession or not, and what features of the data you would look for. Answer: Many answers are possible. You should discuss GDP and other major macroeconomic variables. You should note that you are looking for co-movement and persistence. Diff: 1 Topic: Section: 8.2 Question Status: Previous Edition 23) Use the NBER data in Table 8.1 in the textbook on U.S. business cycle turning points to calculate: a) the shortest business cycle from peak to peak; b) the shortest business cycle from trough to trough; c) the longest business cycle from peak to peak; and d) the longest business cycle from trough to trough. Answer: (a) The shortest business cycle from peak to peak is 17 months, which extended from August 1918 to December 1919. This includes 7 months of contraction followed by 10 months of expansion. (b) The shortest business cycle from trough to trough is 28 months, which extended from July 1980 to October 1982. This includes 12 months of expansion followed by 16 months of contraction. (c) The longest business cycle from peak to peak is 128 months, which extended from July 1990 to March 2001. This includes 8 months of contraction followed by 120 months of expansion. (d) The longest business cycle from trough to trough is 128 months, which extended from March 1991 to November 2001. This includes 120 months of expansion followed by 8 months of contraction. 8.3 1) An economic variable that moves in the same direction as aggregate economic activity (up in expansions, down in contractions) is called A) procyclical.
