25
What does a price index measure?
Measures the cost of a specific basket of goods and services relative to its cost in a prior (base) period. ## Footnote
26
How is the inflation rate most often calculated?
As the annual percentage change in a price index. ## Footnote
27
What is CPI?
* Consumer Price Index * Most often used price index * Based on the purchasing patterns of a typical household.
28
What is headline inflation?
A percentage change in a price index for all goods. ## Footnote
29
How is core inflation calculated?
Calculated by excluding food and energy prices from a price index because of their high short-term volatility. ## Footnote
30
What in the Laspeyres price index based on?
The cost of a specific basket of goods and services that represents actual consumption in a base period.
31
What causes the Laspeyres index to be biased upward?
1. New goods, 2. Quality improvements, and 3. Consumers’ substitution of lower-priced goods for higher-priced goods over time.
32
What is the Paasche price index based on?
* Current consumption weights for the basket of goods and services for both periods and * Reduces substitution bias.
33
What is a Fisher price index?
The geometric mean of a Laspeyres and a Paasche index. ## Footnote
34
What is the cause of Cost-Push Inflation?
Results from a decrease in aggregate supply caused by an increase in the real price of an important factor of production, such as labor or energy. ## Footnote
35
What causes Demand-Pull Inflation?
Results from persistent increases in aggregate demand that increase the price level and temporarily increase economic output above its potential or full-employment level. ## Footnote
36
What does the non-accelerating inflation rate of unemployment (NAIRU) represent?
Represents the unemployment rate below which upward pressure on wages is likely to develop. ## Footnote
37
What are leading indicators?
Leading indicators have turning points that tend to precede those of the business cycle.
38
What are coincident indicators?
Coincident indicators have turning points that tend to coincide with those of the business cycle. ## Footnote
39
What are lagging indicators?
Lagging indicators have turning points that tend to occur after those of the business cycle. ## Footnote
40
What is a limitation of using economic indicators to predict business cycles?
