Consumption Choice Sets

Definition: A consumption choice set includes all available consumption options for a consumer.
Constraints on consumption arise from limitations like budget, time, and other resources.

Budget Constraints

Representation: A consumption bundle is denoted as (x1, x2,..., xn), where xi represents units of commodity i.
Price Representation: Commodity prices are denoted by the vector (p1, p2,..., pn).
Affordability Condition: A bundle (x1,..., xn) is affordable if m ≥ p1x1 + p2x2 + ... + pnxn, where m is the consumer's income.

Budget Set and Constraint

Definition: The budget constraint represents the set of bundles that are just affordable, forming the upper boundary of all affordable bundles.
Impact of Budget Changes:
- An increase in income shifts the budget constraint outward.
- An increase in the price of a good pivots the budget constraint inward.

Income Changes and Budget Constraint Effects

Higher Income: Shifts the budget constraint outward, improving consumer choice without losing existing options.
Lower Income: Shifts the budget constraint inward, likely resulting in loss of choice and potential worse-off status for the consumer.

Price Changes and Budget Constraint Effects

Decrease in Price: Pivots the budget constraint outward, allowing for more choices.
Increase in Price: Pivots the budget constraint inward, resulting in reduced choices and possibly making the consumer worse off.

Ad Valorem Sales Taxes

Definition: A tax levied at a rate t increases prices from p to (1 + t)p; for example, a 17% tax increases prices to 1.17p.
Effect on Budget Constraint: Changes the budget constraint correspondingly, affecting affordability of commodities.

Relative Prices

Concept of Numeraire: Relative prices determine the budget constraint.
Changing numeraire does not affect the budget constraint but simplifies calculations.

Shapes of Budget Constraints

Straight Line Constraints: Result from constant prices, indicating a fixed slope.
Curved Constraints: Arise when prices vary, such as bulk discounts or penalties for excess purchasing.

Quantity Discounts and Penalties

Quantity Discounts: The budget line may kink when bulk buying discounts are applied, impacting slope and affordability at different quantities.
Quantity Penalties: Results in an initially less steep slope that becomes steeper beyond a certain quantity, reflecting higher prices for additional units.

General Choice Sets

Constraints: Choices are influenced by multiple factors beyond budget, including time and resource limitations.

The Food Stamp Program

Explanation: Food stamps are specifically designed for food purchases, modifying a family's budget constraint.
Budget Implications: Allows families to purchase more food without reducing spending on other goods due to increased effective income from food stamps.
