1. Measures associated with Real GDP

2. Real GDP trend: Long-term movement in Real GDP data. Several techniques.

3. Real GDP growth: Example: 2005 US Real GDP (constant US$) = 11046 billions 2006 US Real GDP (constant US$) = 11410 billions

4. Average growth rates: US:3.2% ARG:2.1%

5. Real GDP growth volatility: where In this case x = real GDP growth Example:

6. Business cycle :

7. Unemployment Basic definitions Labor force: People 16 years old or older who are employed or looking for work. Employed: Any person 16 years old or older (1) who works for pay, either for someone else or in his or her own business for 1 or more hours per week; (2) who works without pay for 15 or more hours per week in a family enterprise; or (3) who has a job but has been temporarily absent, with or without pay. Unemployed: A person 16 years old or older who is not working, is available for work, and has made specific efforts to find work during the previous 4 weeks.

8. labor force = employed + unemployed unemployment rate = unemployed employed + unemployed population = labor force + not in labor force labor force participation rate = labor force population

10. Unemployment rates across the world

11. Types of unemployment: Frictional unemployment: The portion of unemployment that is due to the normal working of the labor market; used to denote short-run job/skill matching problems. Structural unemployment: The portion of unemployment that is due to changes in the structure of the economy that result in a significant loss of jobs in certain industries.

14. US alone

15. US and Argentina together Accumulated inflation: US:580% ARG: 248,370,890,124,673 %

16. Costs of inflation 1) It reduces the overall standard of living by making goods and services more expensive (false statement) People’s income from wages and salaries, profits, interest, and rent increases during inflations. 2) Changes the distribution of income If your income is fixed and prices rise, your ability to purchase goods and services falls proportionately. Indexation. 3) Effects on debtors and creditors If the actual inflation is higher (lower) than the expected inflation debtors (creditors) benefit. 4) Administrative Costs and Inefficiencies Alternative use of time. Intense use of banks. Relative prices uncertainty. 5) Increased risk, reduced investment and slower economic growth
