Explanation:

In economics and particularly in consumer choice theory, the income-consumption curve is a curve in a graph in which the quantities of two goods are plotted on the two axes; the curve is the locus of points showing the consumption bundles chosen at each of various levels of income.

The income effect in economics can be defined as the change in consumption resulting from a change in real income.[1] This income change can come from one of two sources: from external sources, or from income being freed up (or soaked up) by a decrease (or increase) in the price of a good that money is being spent on. The effect of the former type of change in available income is depicted by the income-consumption curve discussed in the remainder of this article, while the effect of the freeing-up of existing income by a price drop is discussed along with its companion effect, the substitution effect, in the article on the latter. For example, if a consumer spends one-half of his or her income on bread alone, a fifty-percent decrease in the price of bread will increase the free money available to him or her by the same amount which he or she can spend in buying more bread or something else.

The consumer's preferences, monetary income and prices play an important role in solving the consumer's optimization problem (choosing how much of various goods to consume so as to maximize their utility subject to a budget constraint). The comparative statics of consumer behavior investigates the effects of changes in the exogenous or independent variables (especially prices and money incomes of the consumers) on the chosen values of the endogenous or dependent variables (the consumer's demands for the goods).
