Description: Change Solved Problem 4.3 so that Lisa's budget and the price of pizza double, but the price of burritos remains constant. Show how her budget constraint and opportunity set changes. Is Lisa necessarily better off than before these changes? (Hint: What happens to the intercepts of the budget line?)

Key Concepts

Income and Price Change Effects

This concept deals with how simultaneous changes in income and the prices of goods affect a consumer’s purchasing power. When income and the price of one good change by the same proportion while the price of another remains constant, the shape of the budget line changes, potentially altering the trade-offs between goods. Analyzing these effects helps to understand whether the consumer is better off or worse off after the changes.

Intercept Analysis of the Budget Line

Intercept analysis involves examining where the budget line intersects the axes, which represents the maximum amount of one good that can be purchased if all income is spent on that good. Changes in income or the price of one good will alter these intercepts, revealing shifts in the consumption possibilities available to the consumer.

Welfare Comparison

Welfare comparison is the evaluation of whether a given change in income and prices improves the ability of a consumer to achieve higher satisfaction or utility. Even if some aspects of the budget constraint improve (such as the intercept for a good remaining constant or increasing), the overall impact on well-being depends on how the relative prices and available choices are affected.

Budget Constraint

The budget constraint represents all the possible combinations of goods that a consumer can purchase given their income and the prices of the goods. It is fundamental in understanding consumer choice because it sets the limit on what can be bought, and any changes in income or price will shift or rotate this line, thereby altering the available choices.

Opportunity Set

The opportunity set is the collection of all bundles of goods that a consumer can afford, given their budget constraint. It defines the range of options available for consumption and is directly affected by changes in income or prices, which can either expand or contract the set of feasible choices.
