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.2: Shows the relationship between after-tax income and consumption expenditures for different income quintiles in the US.
