Study Notes
Economics: The Study of Choice
- Economics centers around how individuals and societies make choices with limited resources.
- The key concept is choice based on the scarcity of resources.
Three Fundamental Concepts
- Opportunity Cost: The value of the best alternative forgone when making a decision.
- Marginalism: Analyzing the incremental costs or benefits of a choice.
- Efficient Markets: Markets where profit opportunities are quickly eliminated.
Applications of Economics
- Rainfall and Schooling in India: In rural India, heavy rainfall increases the opportunity cost of sending children to school due to increased demand for farm labor.
- Urban/Rural Education Gap: The urban/rural gap in education scores widens during high rainfall periods because urban children have fewer work opportunities.
Microeconomics & Macroeconomics
- Microeconomics: Focuses on individual units (households, firms, industries), examining the behavior of individual decision-making units within the economy.
- Macroeconomics: Analyzes the aggregate behavior of the entire economy, including national income, employment, output, and price levels.
Methods in Economics
- Positive Economics: Describes and explains economic phenomena without making value judgments. Focuses on what is "true" about the economy.
- Normative Economics: Evaluates economic outcomes as good or bad and proposes actions to improve the economy. Focuses on what "ought to be" done.
Graphs & Tools
- Ceteris Paribus: "All else equal" assumption used to study the relationship between two variables while holding other factors constant.
- Graphs: Visual representations of data, using X-axis (horizontal) and Y-axis (vertical).
- Slope: A measurement indicating the direction and magnitude of the relationship between two variables.
- Positive Relationship: An increase in one variable leads to an increase in the other variable (both move in the same direction).
- Negative Relationship: An increase in one variable leads to a decrease in the other variable (they move in opposite directions).
- Slope of a Line: Changes in the Y variable divided by changes in the X variable.
- Positive Slope: Indicates a positive relationship between the variables.
- Negative Slope: Indicates a negative relationship between the variables.
- Linear Relationship: A constant slope between two variables.
- Non-linear Relationship: A changing slope between two variables.
Key Figures & Tables
- Table 1A.1: Illustrates the relationship between total disposable personal income and years in the US.
- Table 1A.2: Shows the relationship between after-tax income and consumption expenditures for different income quintiles in the US.
- Figure 1A.1: A graph of total disposable personal income in the US from 1975-2017.
- Figure 1A.2: A graph depicting the relationship between household consumption and income, using data from Table 1A.2.
