Document Summary

The satisfaction that a consumer receives from consuming some good or service. The consumers total satisfaction resulting from consumption of a given product. The additional satisfaction obtained from consuming one additional unit of the pr. The utility that any consumer derives from successive units of a particular produc time diminishes at total consumption of the product increases. We assume consumers are profit maximizers, so that the marginal utility obtained each product is equal. Ex let x = juice and let y = all other products taken together. You have a decision to make, spend more on apple juice and less on everyth around. The market demand curve is the horizontal sum of all the individual demand curve. 6. 2 income and substitution effects of price changes. Real income ice ct e product (declining) duct consumed over some period of ined from the last dollar spent on do if there was an increase in apple erything else or the other way urves.
