12. Business Cycle not a regular, predictable, or repeating phenomenon like the swing of the pendulum of a clock. Its timing is random & unpredictable.

13. 4 Phases of the Business Cycle A sequence of four phases. Expansion Peak Contraction Trough

14. Phases of the Business Cycle 1.Expansion: speedup in the pace of economic activity & a rise in real GDP Recovery: right after a trough, economy is getting better Prosperity: right before a peak, economy is at its best economic growth 2.Peak: upper turning of a business cycle When GDP stops rising

15. Phases of the Business Cycle Contraction: slow down in the pace of economic activity Economic decline marked by falling GDP Recession: 6 straight months of contraction Depression: Especially long contraction Trough: lower turning point of a business cycle, where a contraction turns into an expansion GDP stops falling

16. **A trough & peak both represent a turning point in the business cycle**

18. National Debt http://www.usdebtclock.org/

19. National Debt the total amount of money the Federal Government owes to bondholders. The debt is owed to investors who hold treasury bonds. If you invest in a treasury bond, the money that one uses to buy the bond is used to finance the National Government. A bond is essential an IOU issued by the government as a way for them to borrow money.

20. Problems of the National Debt Reduces the funds available for businesses to invest. The government must pay interest to bondholders, the more the government borrows, the more interest it has to pay. Roughly, to pay off the National Debt today, each citizen would have to pay just over $51,925

21. When President Bush took office over 10 years ago, the national debt was at $5.6 trillion; since then, big budget surpluses have collapsed into huge deficits, & the debt has shot up more than 50 percent. When Obama took office it was $9.986 trillion
