ECON 002 Lecture Notes - Lecture 3: Gdp Deflator, Iphone 5, Iphone 6
Document Summary
Econ-002: macro economics lecture 3 inflation part 1. Three approaches: gdp deflator (last lecture), cpi, pced. Consumer price index = a measure of the average change over time in the prices paid by (urban) consumers for a typical market basket of consumer goods and services (i. e. not stocks, or bonds) Three biggest component: housing, transportation, food and beverage. In macro econ class, the question will tell you what the basket and price is. It will also tell you what the base period/ year is. Compute the basket cost (bk) of current year = pbk * qbk. Compute the basket cost of base period. Inflation = 100 * (cpit - cpit-1 )/ cpit-1. Gdpd does not include foreign imported goods. Cpi does not include investment/ capital goods. Their market basket is completely different i. e. tractors. Substitution bias: cpi ignores substitution effect the purchase of substitute goods when price of one changes/ change in income.
