  2. TEKS (10) Economics. The student understands key economic measurements. The student is expected to: (A) interpret economic data, including unemployment rate, gross domestic product, gross domestic product per capita as a measure of national wealth, and rate of inflation; and (B) analyze business cycles using key economic indicators.

  3. Teaching the Terms • Unemployment • Recession • Frictional • Structural • Cyclical • Inflation • Deflation • Price index • Indexing • Hyperinflation

  4. Macroeconomic Issues Recessions Unemployment Inflation Distribution

  5. Long-Run Growth Trend Real GDP Expansion Recession Time Business Cycle Peak Trough

  6. Recession A recession is a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in production, employment, real income, and other indicators. http://www.nber.org/dec2008.pdf

  9. Labor Force

  10. Unemployment • Every person who is 16 years old or older (the working-age population) and not institutionalized falls into one of three categories • Employed – a person who has worked full- or part-time during the past week or is on vacation/sick leave • Unemployed – a person who did not work in the past week but sought work in the past four weeks • Out of the labor force – did not work or seek employment

  11. Unemployment Labor force = Employed + Unemployed Unemployment rate = Unemployed ÷ Labor Force Participation rate = Labor force ÷ Working Age (16+) Population

  12. Criticisms of Measurement Discouraged workers Involuntary part-time workers Underemployed Types of employment

  13. Unemployment

  14. Types of Unemployment: Frictional Short-term unemployment associated with matching workers with jobs Costs are small (may even be negative)

  15. Types of Unemployment: Structural Long-term and chronic unemployment that exists when an economy is producing at a normal rate Mismatch of unemployed workers and available jobs Very high costs related to its long-term nature

  16. Types of Unemployment: Cyclical • Occurs during a period of recession (unusually low production) • High costs both to worker and to society • Lost production (output) • Lost income for unemployed workers • Lost tax revenue and increased government support

  17. Natural Rate of Unemployment • Full employment ≠ zero unemployment • Full employment = no cyclical unemployment

  18. Inflation Inflation is an increase in the overall level of prices. Inflation is not an increase in the price of a specific good or service relative to the prices of other goods and services.

  19. Measuring Inflation • Use a price index that measures the cost of a fixed market basket of goods relative to the cost of the same basket in a base year • Examples • Consumer Price Index (CPI) – BLS • GDP Deflator – BEA • Personal Consumption Expenditures Price Index – BEA

  20. Computing a Price Index • Select a market basket • Compute the price of the basket in each year • Select a base year • Current year price ÷ Base year price = Price index • Simulation – Candy Price Index • Denise Hazlett athttp://people.whitman.edu/~hazlett/econ/

  21. Simulation: Step 1 • Individually • Select a mix of candy that costs 30¢ for each of the periods • As a group • Agree to a market basket that is representative

  22. Simulation: Step 2 • Calculate the total price of a market basket in each period, using a basket of: • 2 Kisses • 3 Reese's • 1 Lifesaver

  23. Simulation Instructions • Calculate the Candy Price Index for each period • CPI = (Price current / Price base ) * 100 • For Period 1: CPI = (45¢ / 30¢) * 100= 150 • Calculate the inflation rate between each period. • Inflation rate = (CPI2 – CPI1) / CPI1 • Inflation between period 1 and 2 = (117 – 150) / 150 = -22%

  26. Issues with Market Baskets Substitution bias – a fixed basket ignores consumers’ ability to substitute away from items that have become relatively more expensive New product bias – a fixed basket does not account for the value to consumers of newly available goods and services Quality bias – a fixed basket does not adequately account for change in the quality of goods and services

  27. Constructing a Market Basket • Questions • What is the scope of the market basket? • How often is the market basket updated? • Different baskets • CPI – the purchases of a typical urban consumer • GDP Deflator – the entire production of the economy • PCE – personal consumption expenditures

  28. Computing the Indexes • CPI – a historic basket at current prices How much does it cost to buy the old basket this year? • GDP – a current basket at historic prices How much would it have cost to buy this year’s GDP at some point in the past? • PCE – combines both measurement techniques and takes an average of the two

  29. Comparing Indexes • The fixed basket used by CPI might not account for • Improvements in the quality of goods and services • The ability of consumers to substitute cheaper goods and services for more expensive ones • The changing basket of GDP might not reflect the loss of welfare from substitutions • PCE price index is a blend of the fixed basket and the changing basket

  30. PCE Price Index • Since 2000, PCE has been the Fed’s preferred inflation measure • Advantages • Bigger “basket” of goods & services than CPI • Expenditure weights updated monthly (CPI updates every 2 years) • Disadvantages • Slower to release than CPI • Subject to data revisions

  31. Using a Price Index Deflate nominal value Index values to reflect changing price level Calculate the rate of inflation

  32. Nominal vs. Real Variables • Nominal variables are measured using current prices • Real variables have been adjusted for inflation by using prices from a base year • Examples • Real wages • Real GDP • Real interest rate

  33. Deflating a Nominal Value Convert a nominal value to a real value to remove the effect of inflated prices – allows values to be compared over time. Real = Nominal ÷ (Price Index/100) Handout: Inflation at the Movies

  34. Box Office Winners (and Losers)

  35. Indexing • Converts a real value to a nominal value by increasing a nominal quantity by an amount equal to the percentage increase in a price index • Allows an employer or government to maintain purchasing power of salaries and benefits • Examples • Candy consumption • Indexed labor contracts (COLAs) • Social Security payments

  36. Rate of Inflation Shows the rate of change of prices over time Rate of inflation is the percentage rate of change in a price index Rate of inflation = (PI2 – PI1) / PI1

  37. Costs of Unexpected Inflation • Redistributions of wealth Creditors / Debtors and Employees (on contract) / Employers • Interference with long-term planning Future purchasing power is uncertain • “Noise” in the price system Information conveyed by prices becomes difficult to interpret • Shoe leather costs Time and effort spent to minimize the effect of inflation • Distortions of the tax system “Bracket creep” and future value of depreciation allowances

  38. Hyperinflation • Excessive monetary growth → hyperinflation • Examples • Nicaragua (1988) – 33,000% inflation • Germany (1923) – 102 million% inflation • Hungary (1945) – 3.8 * 1027% inflation • Harm of inflation is magnified.

  39. Causes of Inflation • Long-run • Too much money chasing too few goods • “Inflation is always and everywhere a monetary phenomenon…” (Milton Friedman) • Short-run • Expectations • Excess demand • Supply shocks

  40. Distribution of Income • Lorenz curve is a curve showing how the actual distribution of income differs from an equal distribution of income in a nation
