51: utility maximization Flashcards
utility
measure of personal satisfaction produced by consumption
util
one unit of utility
marginal utility
change in total utility generated by consuming one additional unit of that good
marginal utility curve
shows how marginal utility depends on the quantity consumed
principal of diminishing marginal utility
the additional satisfaction a consumer gets from one more unit of a good declines as the amount consumed increases
budget constraint
limits the cost of a consumer’s consumption to no more than their income
consumption possibilities
the set of all consumption bundles that are affordable, given the consumer’s budget constraint and prices
budget line
curve showing all maximum consumption possibilities
optimal consumption bundle
bundle that maximizes utility given a budget constraint
marginal utility per dollar
additional utility from spending one more dollar on a good
marginal utility per dollar equation
MUx / Px
optimal consumption rule
in order to maximize utility, a consumer must equate the marginal utility per dollar on each good in the budle
optimal consumption rule equation
MUx / Px = MUy / Py = …
location of optimal consumption bundle
on the budget line where the marginal utility per dollar curves meet
