Study Notes
Thinking Like An Economist
- Economics trains you to think about alternatives, evaluate the cost of choices, and understand how events and issues are related.
- The economic way of thinking involves analytical and objective thinking, and uses the scientific method.
Economic Models
- Economists use simplified models to explain complex real-world situations.
- Models are simplified representations of a specific part of the world.
- Models help to generate hypotheses that can be tested.
Importance Of Data
- Data quality is crucial to economic analysis.
- Time series data, cross-section data, and panel data are important data types in economics.
Time-Series Data
- A time series is a sequence of the same variable measured at different points in time.
- Time series data is presented in tabular or graphical format, but charts and diagrams must be interpreted with care.
- High-frequency data can be detailed, making averages (monthly, quarterly, or annually) useful for presentation.
Cross-Section and Panel Data
- Cross-section data compares economic variables across different individuals or groups at a specific point in time.
- Panel data tracks observations across multiple time periods for the same individuals or groups.
- Cross-section and panel data often need adjustments to ensure accurate comparisons.
Economic Models And Assumptions
- Economists use assumptions to simplify the world and make it easier to understand.
- Assumptions help economists to answer different questions.
Econometrics
- Econometrics helps economists to estimate relationships between two or more variables simultaneously, while controlling for factors.
- This helps to address the "other things equal" problem, assuming the right variables are included.
- Established relationships can be used to test hypotheses, predict the impact of changes, and make predictions.
Correlation Vs. Causation
- Correlation does not equal causation.
- It is important to consider other factors when analyzing relationships between variables.
Some Basic Economic Models
- Some general economic models are used to simplify reality and improve our understanding.
- The Production Possibilities Frontier and The Circular Flow Model are two examples.
The Production Possibilities Frontier (PPF)
- The PPF is a graph showing the combinations of outputs an economy can produce with available factors of production and technology.
- The PPF illustrates concepts like efficiency, trade-offs, opportunity cost, and economic growth.
The Circular Flow Model
- The circular flow model visually shows how money flows through markets between households and firms.
- It simplistically represents how economic agents are connected.
The Economist As A Policy Advisor
- Economists are scientists when explaining the world and policy advisors when trying to influence it.
Positive vs. Normative Analysis
- Positive statements describe the world as it is, and are descriptive.
- Normative statements express views on how the world should be, and are prescriptive.
Why Economists Disagree
- Economists may disagree on the validity of positive theories, or they may have different values leading to different normative viewpoints on policy.
