Study Notes

Decision-Making in an Economy

Two main categories: Consumers and Firms.
Consumers aim to maximize satisfaction from consumption; firms aim to maximize profit.

Consumer Theory

Studies how individuals spend money based on preferences and budget constraints.
Helps predict consumer behavior, aiding vendors in product sales and economists in understanding economic dynamics.
Assumes rational choices, which is a point of critique.

Budget Constraint

Defines the maximum amount available to spend based on income, earnings, and loans.
Requires efficient allocation of funds to purchase goods and services.
Highlights scarcity of resources and necessitates trade-offs when prioritizing needs and wants.

Budget Line

Illustrates combinations of two goods that can be purchased within given income and prices.
Equation of a budget line:
- M = Px × Qx + Py × Qy
- M represents income, Px and Py are prices of goods, Qx and Qy are quantities.

Example of Budget Line

Mary’s budget: ₹250 for apples (₹10) and oranges (₹5).
Budget line equation derived from values: ₹250 = ₹10 × Qx + ₹5 × Qy.

Budget Set

Represents combinations of two goods affordable at given income and prices.

Slope of the Budget Line

Indicates the trade-off rate between two goods, calculated as the negative price ratio:
- Slope = -Px / Py.

Concept of Utility

Utility measures total satisfaction from consuming products or services.
Different individuals derive varying satisfaction from the same goods.
Utility can change based on factors like location and seasonality.

Aspects of Utility

Total Utility (TU): Overall satisfaction from consuming a quantity of goods.
Marginal Utility (MU): Additional satisfaction from consuming one more unit.
Utility can be cardinal (measurable) or ordinal (ranked preference).

Diminishing Marginal Utility

Describes decreased additional satisfaction from consuming more units of a good.
Example: Satisfaction from the first slice of pizza is higher than from subsequent slices.

Utility Maximization

Consumers should allocate income so that the last dollar spent on each good yields the same marginal utility.
Essential for making optimal purchasing decisions.
