Chapter 5 The Consumption Decision Flashcards
normal goods
consumption increases as income increases
income elasticity of demand
measures how much consumption of a particular good increases with income
income elasticity of demand = % change in consumption / % change in income
inferior goods
consumption decreases as income increases (negative income elasticity)
income effect
reduced consumption of a good whose price has increased; this decrease in buying power often causes reduced consumption of all goods, including the higher priced good
substitution effect
reduced consumption of a good due to an increase in price that leads to a trade-off of the good for a relatively less expensive substitute good
utility
benefits from consumption individuals get from the combination of goods they consume
marginal utility
extra utility of an individual unit of a good
diminishing marginal utility
as an individual accumulates more and more of a good, each successive increment increases his/her utility less
consumer surplus
the difference between what you paid and what you would have been willing to pay (area under demand curve but above price)
behavioral economics
field of economics that rejects the basic model of consumer choice, arguing instead to draw upon the findings of psychologists and economists who conduct laboratory experiments to study the ways people actually make choices
endowment effect
people value more highly the items they happen to possess
loss aversion
individuals are particularly sensitive to losses
status quo bias
reference points of consumption may matter more than absolute consumption in terms of utility; behavior tends toward the default
indifference curve
gives the combination of goods among which an individual has no preference, or which yield the same level of utility
marginal rate of substitution
slope of indifference curve; how much of a good an individual is willing to give up in return for one more unit of another good
