ANS:TDIF:1REF:33-2 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Classical economicsMSC: Definitional 2.Because economists understand what things change GDP, they can predict recessions with a fair amount of accuracy. ANS:FDIF:1REF:33-1 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Economic fluctuationsMSC:Analytical 3.Most macroeconomic variables that measure some type of income, spending, or production fluctuate closely together. ANS:TDIF:1REF:33-1 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Economic fluctuationsMSC:Interpretive 4.Like real GDP, investment fluctuates, but it fluctuates much less than real GDP ANS:FDIF:1REF:33-1 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Economic fluctuations | InvestmentMSC:Definitional 5.When output rises, unemployment falls.

ANS:FDIF:1REF:33-2 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Monetary neutralityMSC: Definitional 7.Most economists believe that classical theory describes the world in the short run but not in the long run. ANS:FDIF:1REF:33-2 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Classical dichotomyMSC: Interpretive 8.A change in the money supply changes only nominal variables in the long run. ANS:TDIF:1REF:33-2 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Monetary neutralityMSC: Definitional 9.The explanations for the slopes of the aggregate demand and short-run aggregate supply curves are the same as the explanations for the slopes of demand and supply curves for specific goods and services. ANS:FDIF:1REF:33-2 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Aggregate demand slope | Short-run aggregate supply slope MSC: Definitional 10.The aggregate-demand curve shows the quantity of domestic goods and services that households, firms, the government, and customers abroad want to buy at each price level. ANS:TDIF:2REF:33-2 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Aggregate-demand curveMSC: Definitional 2184 Chapter 33/Aggregate Demand and Aggregate Supply2185 11.A decrease in the price level makes consumers feel wealthier, so they purchase more. This logic helps explain why the aggregate demand curve slopes downward. ANS:TDIF:1REF:33-3 NAT:AnalyticLOC:Aggregate demand and aggregate supply TOP:Wealth effectMSC: Analytical 12.Other things the same, a decrease in the price level makes the interest rate decrease, which leads to a depreciation of the dollar in the foreign-currency exchange.
