Document Summary

Consumer theory consumers maximize their wellbeing using their preferences to trade off the purchase of more of some goods for less of others. Or dq/dp x p/q point elasticity of demand price elasticity at a particular point on the demand curve. price elastic because the percentage decline in quantity demanded is greater than the percentage increase in price. If the price elasticity is less than 1 in magnitude, demand is said to be price inelastic. Bundle a mix of quantity of two items e. g. bundle a = 12 eggs, 1 bread bundle b = 0 eggs, 2 bread. Rational behaviour we assume that consumers have stable preferences and they act on those preferences. Preference ordering function orders bundles in terms of how much you like them. U is ordinal (puts things in order), not cardinal (how much more we like something) Indifference curve collection of al the bundle amongst which have the same utility, a~b.
