Study Notes
Positive & Normative Economics
- Positive economics explains how the economy works objectively.
- Normative economics provides recommendations based on personal values.
Economic Models
- Models are simplified representations of reality.
- They consist of descriptions, assumptions, and outcomes.
- A good model makes accurate assumptions.
- An outcome of a model is its equilibrium, which generates hypotheses.
Economic Data
- Economic data provides evidence about economic behavior.
- Behavioral laws are theoretical relationships supported by evidence over time.
- Economic experiments can be conducted in labs or in the field.
- Index numbers express data relative to a base value.
Consumer Price Index (CPI)
- CPI measures the rate of growth of an index of consumer prices.
- Inflation rate measures the percentage increase in the average price of goods and services.
Nominal vs. Real Values
- Nominal values are measured in current prices.
- Real values adjust nominal values for changes in the price level.
- Real/Relative Price = (Nominal Price / CPI) x 100
Purchasing Power of Money
- The purchasing power of money measures the quantity of goods that can be bought for €1.
Economic Growth
- Economic growth refers to the increased capacity of an economy to produce goods and services.
- It's measured by the rate of increase in real GDP.
Other Things Equal
- This principle helps isolate the relationship between two variables while acknowledging the influence of other variables.
Correlation vs. Causation
- Correlation doesn't imply causation; just because two variables move together doesn't mean one causes the other.
Econometrics
- Econometrics uses statistics to measure relationships in economic data.
Production Possibility Frontier (PPF)
- The PPF shows the maximum amount of one good that can be produced for each output level of another good.
- Points inside the PPF are inefficient.
- The PPF illustrates efficiency, trade-offs, opportunity cost, and economic growth.
