Micro Midterm 2 Consumers and Incentives
why are consumers price takers
individual transactions are too small to have much impact on the market price
for a consumer with a given level of income, the combinations of goods for the budget constraint will be _____ than of the budget set
lower
incentive to change your behavior goes away when
two ratios are equal
which is better, cash or in kind transfer
usually cash, or equally well of with in kind, never better off with in kind
the buyers problem: preferences
we all want the biggest bang for our buck, what we actually buy reflects our tastes and preferences
why does the demand curve have a negative slope
when the price is lower, people will want to buy more
how does a consumer's budget set differ from his budget constraint
a budget set refers to all of the possible bundles of goods and services a consumer can purchase, while a budget constraint is limited to the bundles he can purchase using all of his income
what are necessary ingredients to the buyers problem
amount of money the consumer has to spend, consumer's tastes and preferences, prices of goods and services
the amount of apples and bread that a consume could choose using his or her entire budget is
budget constraint
combinations of apples and laces of bread that a consumer could purchase would represent
budget set
three areas defined by budget constraint
bundles on the line, bundles inside the line, bundles outside the constraint
your parents will give you either a check for $80, or two sweaters. which is cash and which is in kind
check is cash, sweaters are in kind
cash transfer
direct transfer payments of money to eligible people, provided by state and federal government
a consumer's budget constraint refers to the collection of all possible bundles that
exactly exhaust a consumer's entire budget
a decrease in a consumer's income causes her budget constraint to encompass _______ bundles
fewer
for economists, the buyer's problem refers to
how consumers arrive at a choice as to what to purchase
a price increase causes what on a budget constraint
inward pivot
a decrease in income causes what on a budget constraint
inward shift
a price decrease causes what on a budget constraint
outward pivot
an increase in income causes what on a budget constraint
outward shift
what makes up the buyer's problem
preferences, cost (prices), income/wealth
the buyers problem: cost
prices are fixed (no negotiation), we can buy as much as we want of something without driving the price up (because of an increase in demand)
budget constraint line
shows relationship between quantities of two goods
if an individual consumes goods X and Y and is currently maximizing her total benefits
the marginal benefits per dollar spent are the same for both goods, the equal bang for buck rule is adhered to, no other consumption choice can make total benefits greater, MBx/Px = MBy/Py
a consumer's satisfaction is maximized when the marginal benefit from the last dollar she spent on one good is equal to the marginal benefit from the last dollar she spent on another good because
the reality of diminishing marginal benefits assures that any shift in consumption toward either good must necessarily maker her worse off
equilibrium means
there is no incentive to change your behavior
the buyers problem: income/wealth
there is no saving or borrowing, only buying, even though we use a straight line to represent purchase choices, we only purchase whole units
in kind transfer
you transfer your specific investments over to the new company without selling and buying
