Study Notes
Positive and Normative Economics
- Positive Economics: Explains how the economy works objectively and scientifically.
- Normative Economics: Provides recommendations based on value judgments.
Economic Models
- Model: A simplified representation of reality used to predict behavior.
-
Main Parts of an Economic Model:
- Description of individuals and variables
- Assumptions (accurate assumptions are crucial)
- Outcomes (equilibrium of the model, leading to hypotheses)
Data and Laws
- Data: Pieces of evidence about economic behavior.
- Behavioral Law: A sensible theoretical relationship not refuted by evidence over a long period.
- Economic Experiments: Laboratory or field experiments can validate theories.
Indices
- Index Number: Shows data relative to a base value (e.g., (Value at t / value in base year) x 100).
- Consumer Price Index (CPI): Measures the rate of growth of an index of consumer prices (inflation).
- Inflation Rate: The percentage increase in the average price of goods and services.
Values
- Nominal Values: Measured in the prices ruling at the time of measurement.
- Real Values: Nominal values adjusted for changes in the price level.
- Real/Relative Price: (Nominal Price / CPI) x 100
Other Concepts
- Purchasing Power of Money: An index of the quantity of goods that can be bought for a given currency.
- Economic Growth: The increase in an economy's capacity to produce goods and services over time (measured by the rate of increase in real GDP).
- Other Things Equal: Analysis tool in economics, focusing on the relationship between two variables while holding other variables constant.
Production Possibility Frontier (PPF)
- Shows the maximum possible output combinations of two goods.
- Points inside the PPF indicate inefficiency.
- Points outside the PPF are currently unattainable.
Two-Factor Circular Flow Model
- Visual model of the economy showing money flow through markets (households and businesses).
- Highlights the relationship between households and businesses.
