  1. Do Now In the future would you invest in mutual funds? Are they a good investment? Are stocks a better investment than mutual funds, in your opinion?

  2. How is Inflation measured? • The government tracks the prices of the same goods and services each year. • This “market basket” is made up of about 364 commonly purchased goods • The Inflation Rate-% change in prices in 1 year • They also compare changes in prices to a given base year (usually 1982) • Prices of subsequent years are then expressed as a percentage of the base year • Examples: • 2005 inflation rate was 3.4% • U.S. prices have increase 98.3% since 1982 (base year). • The inflation rate in Bolivia in 1985 was 50,000% • This is called Hyperinflation • A $25 meal today would cost $12,525 a year later

  3. Turn ‘n Talk With your neighbor, List: What are some of the 364 goods should the government track?

  4. What is the CPI? • Most popular price index = CPI (Consumer Price Index) – series used to measure price changes for a representative sample of frequently used consumer items • tracks monthly changes in prices paid by urban consumers for a representative “basket” of goods & services • Uses the prices of approximately 364 goods & services (i.e. toothpaste (7 oz), milk (1 gal), peanut butter (2lb. jar), light bulb (60-watt), auto engine tune-ups, etc.) • http://www.youtube.com/watch?v=Si37yjZM-SA

  6. Consumer Price Index (CPI) Price of market basket = x 100 CPI Price of market basket in base year • The most commonly used measurement inflation for consumers is the Consumer Price Index • Here is how it works: • The base year is given an index of 100 • To compare, each year is given an index # as well • 1997 Market Basket: Movie is $6 & Pizza is $14 • Total = $20 (Index of Base Year = 100) • 2009 Market Basket: Movie is $8 & Pizza is $17 • Total = $25 (Index of ) 125 • This means inflation increased 25% b/w ’97 & ‘09 • Items that cost $100 in ’97 cost $125 in ‘09

  7. Problems with the CPI • Substitution Bias- As prices increase for the fixed market basket, consumers buy less of these products and more substitutes that may not be part of the market basket. (Result: CPI may be higher than what consumers are really paying) • New Products- The CPI market basket may not include the newest consumer products. (Result: CPI measures prices but not the increase in choices) • Product Quality- The CPI ignores both improvements and decline in product quality. (Result: CPI may suggest that prices stay the same though the economic well being has improved significantly)

  8. In groups What are the current prices of some of these items? How have prices changed since 2008? Have any prices gone down? Make a “market basket” of goods that you have bought during your 4 years as a high school student. How have these prices changed since 2009? Has there been a significant change in prices?
