ECO 181 Lecture Notes - Lecture 2: Gdp Deflator, Real Interest Rate, Capital Good
Document Summary
Measures of the overall cost of goods and services. Inflation rate = cpi this year-cpi last year/cpi last year x 100. The introduction of new goods increases variety. Allows consumers to find products that more closely meet their needs. The cpi misses this effect because it uses a fixed basket of goods. Improvements in the quality of goods in the basket increase the value of each dollar. The bls tries to account for quality changes but probably misses some, as quality is hard to measure. Thus, the cpi overstates increases in the cost of living. Each of these problems causes the cpi to overstate cost of living increases. The bls has made technical adjustments, but the cpi probably still overstates inflation by about 0. 5 percent per year. This is important because social security payments and many contracts have. Included in gdp deflator (if produced domestically) Inflation makes it harder to compare dollar amounts from different times.
