The theory of consumer choice assumes consumers wish to maximise their utility through the optimal combination of goods given their limited budget. to illustrate how consumers choose between different combinations of goods we can use equi marginal principle and indifference curves and budget lines. consumer equilibrium equimarginal. Cardinal utility 2: consumer choice theory.
Consumers equilibrium | indifference curve | part 3 | microeconomicsdon’t forget to subscribe our second channel too ! channel uc6lo. To maximize utility, a consumer chooses a combination of two goods at which an indifference curve is tangent to the budget line. at the utility maximizing solution, the consumer’s marginal rate of substitution (the absolute value of the slope of the indifference curve) is equal to the price ratio of the two goods. Consumer is described by a preference relation and a consumption space, as in the theory of the consumer. we take consumption space to be rl . an important feature of the theory is to account for who owns and sells the goods that the consumers buy. we also need to account for where consumers’ incomes come from. each consumer will. Equation (4) shows that the slope of an indifference curve, dm dc, equals (minus) the ratio of the marginal utilities. of course, this is the same as saying that the marginal rate of substitution equals the ratio of the two marginal utilities (as explained in section 3.6) since dm dc equals the mrs.

In almost all cases, consumer choices are driven by prices. as price goes up, the quantity that consumers demand goes down. this correlation between the price of goods and the willingness to make purchases is represented clearly by the generation of a demand curve (with price as the y axis and quantity as the x axis). Figure 7.15 utility maximization and demand by observing a consumer’s response to a change in price, we can derive the consumer’s demand curve for a good. panel (a) shows that at a price for horseback riding of $50 per day, janet bain chooses to spend 3 days horseback riding per semester.
