What does a change in the price of one commodity do to the budget line?
What does a change in the price of one commodity do to the budget line?
- It pivots the budget line anchoring on the commodity that did not change price. (correct)
- It shifts the budget line away from the origin.
- It causes the budget line to become steeper without affecting the total budget.
- It leads to a decrease in the total income available for spending.

Income effect
Income effect
The change in quantity demanded that arises because a price change lowers consumers' real incomes.
Substitution effect
Substitution effect
The change in quantity demanded due to a change in the relative price of one good compared to other goods.
Law of Diminishing Marginal Utility
Law of Diminishing Marginal Utility
This economic principle states that as consumption of a good increases, the marginal utility (satisfaction) gained from each additional unit decreases.

Study Notes
Marginal Analysis in a Nutshell
- Optimal Activity Level: Maximize an activity until marginal benefit equals marginal cost (zero marginal net yield).
- Relative Activity Levels: Allocate resources to activities with similar marginal benefits. Choose the option with the highest marginal net yield.
Totals, Averages, and Marginals: Arithmetic Relationships
- First Units: At the zeroth unit, total, average, and marginal values are all zero. If not zero, marginal values are still zero.
- Total and Marginal Relationship: Total is the sum of all preceding marginal values.
- Relationship between Average and Marginal: Average rises when marginal is above average and vice versa. Average stays constant when marginal equals average.
Geometry of Marginal Analysis: Total X Curves
- Average X and Total Curve: To find the average profit at a point, draw a line from the origin to that point on the graph and calculate its slope (rise/run).
- Marginal X and Total Curve: To find the marginal profit at a point, determine the slope of the tangent line at that point.
- Total X and Average Curve: The total cost of any quantity (OQ) is the area under the marginal cost curve above the line OQ.
Straight-line Marginal and Average Curves
- For average to rise, the marginal must be above average. Vice versa for average to fall. Marginal equals average when average is constant.
Total x and Marginal curve
- The total cost of producing OQ units of any commodity is the area under the marginal cost curve above the line OQ.
General Marginal and Average Curves
- A tangent line at a given point is used to determine the marginal.
- Extend the tangent line to the vertical axis and calculate the midpoint.
- A perpendicular line from the extended point to the horizontal axis passing through the midpoint is drawn.
