A consumer's budget allows them to purchase two goods. The price of one good decreases, leading the consumer to choose a new combination of goods that provides a higher level of satisfaction. To understand this change in behavior, an analyst constructs a special, non-real budget line. What is the purpose and correct construction of this analytical tool if the goal is to isolate the change in consumption due only to the increase in the consumer's effective wealth?

When analyzing the effect of a price decrease for a good, the hypothetical budget constraint used to isolate the income effect is constructed to be parallel to the new budget constraint and tangent to the original indifference curve.

Isolating the Income Effect

Analyzing a Change in Consumer Choice

An analyst is studying how a consumer's choice between two goods changes after the price of one good falls. To do this, they decompose the total change into two separate effects using a hypothetical budget constraint. Match each analytical component to its correct description.

An economist wants to isolate the 'income effect' resulting from a price decrease for a specific good. This involves constructing a hypothetical budget constraint on a standard indifference curve diagram. Arrange the steps below in the correct order to construct this specific line.

To isolate the change in consumption resulting purely from a change in a consumer's purchasing power, an analytical tool is used. This tool is a line drawn with the same slope as the ______ budget constraint, but it is shifted so that it is tangent to the final indifference curve.

Evaluating the Decomposition of Consumer Choice

An analyst is examining the effect of a price decrease for Good X. A diagram shows the consumer's original budget constraint (BC1) and choice (Point A on indifference curve IC1), and their new budget constraint (BC2) and choice (Point C on indifference curve IC2). To isolate the income effect, a dashed hypothetical budget constraint is drawn parallel to the new budget constraint (BC2) and tangent to the final indifference curve (IC2). Evaluate this construction.

An economist is analyzing how a consumer's choice between two goods changes after the price of one good decreases. To isolate the change in consumption that is due only to the consumer's increased purchasing power (as if they received a lump-sum income boost), the economist constructs a hypothetical budget constraint. Which of the following accurately describes the properties of this specific analytical tool?
