Fundamental terms - Inflation Flashcards
2 key measures used to track changes in price levels over time
1) GDP deflator
2) Consumer price index (CPI)
What does the inflation rate measure?
how much the overall price level in an economy increase over a period in %
What does inflation reflect?
How the purchasing power of money decreases as prices rise
What is the nominal GDP?
The total value of all goods & services produced in an economy at current market prices (without adjustment for inflation)
What is the real GDP?
The total value of all goods and services produced at constant prices (adjusted for inflation)
GDP deflator formula
P = Nominal GDP / Real GDP = €Y / Y
What does the GDP deflator show?
How much of the increase in the GDP is due to inflation, not from real increases of the quantity of goods & services produced
What does the CPI measure?
the average change in prices over time that consumers pay for a fixed basket of goods & services
hat does CPI stand for?
consumer price index
Why do consumers care about CPI? What does it reflect?
It reflects the prices of goods which are typically consumed by households ( eg food, housing, transportation & entertainment).
Consumers care as it directly affects their cost of living
What is the difference between the GDP deflator & CPI
GDP deflator: covers all goods & services produced domestically -> calculated with nominal & real GDP
CPI: only the prices of consumption goods -> provides a more consumer-focused view of inflation
Nominal GDP formula
nominal GDP = Σ(Quantity of goods & services * current prices)
eg: nominal GDP = (cars produced (100) * current price (20000) + (computers produced (200) * current price (1000))
Real GDP formula
Real GDP = Σ( Quantity of Goods & Services * Base year prices)
so a constant price of a base year is used
Difference between nominal GDP & Real GDP
Nominal GDP: uses current prices (including inflation), so price changes and changes in production are reflected
real GDP: uses constant prices from a base year. Allowing to isolate the true growth in production by removing the effect of inflation
