price-consumption curve

economics

Quick Summary

The price-consumption curve in economics illustrates how a consumer's purchasing behavior changes in response to variations in the price of a specific good, while keeping income and other prices constant.1

As the price of a good changes, the consumer's budget line shifts. The price-consumption curve is a locus of points representing the optimal consumption bundles at each price level, found where the budget line is tangent to the consumer's indifference curves. This curve helps visualize the substitution effect and the income effect of price changes on demand. It is a fundamental tool for understanding how consumers adjust their spending habits in response to price fluctuations, ultimately contributing to the shape of the demand curve.12
