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.
