When a consumer shifts purchases from product x to product y, the marginal utility of X rises, and the marginal utility of Y falls.
In economics, utility is the satisfaction or benefit obtained from consuming a product. The marginal utility of a good or service describes how much pleasure or satisfaction a consumer gains or loses by increasing or decreasing his consumption by one unit. There are three types of marginal utility. They are positive, negative, or zero marginal utilities.
Marginal utility is the pleasure obtained by the consumer for each additional unit he consumes. Calculate the utility over the first consumed product (threshold amount). For example, you can buy frozen donuts. In return, this will give you a certain level of benefit or satisfaction.
