MICROECON CH. 3
T/F: A "change in quantity demanded" is a shift of the entire demand curve to the right or to the left.
FALSE
what are the determinants of supply?
technology, resource prices, and number of producers
how is a market DEMAND CURVE derived from individual demand curves?
add up quantities demanded by all individual consumers for each price
how do you derive a market SUPPLY CURVE from individual supply curves?
add up quantities supplied by all individual producers for each price
statement consistent with the LAW OF SUPPLY
an increase in market price will lead to an increase in quantity supplied
characteristics lead to a DOWNWARD SLOPING DEMAND CURVE
an increase in purchasing power as market price decreases; diminishing marginal utility
characteristics leads to a UPWARD SLOPING SUPPLY CURVE
increasing opportunity costs; increasing marginal costs
a price ceiling will result in a shortage only if the ceiling price is (greater than/less than) the equilibrium price
less than

statement consistent with LAW OF DEMAND
a reduction in market price will lead to an increase in quantity demanded
suppose that in the market for computer memory chips, the equilibrium price is $50 per chip. if the current price is $55 per chip, then there will be a (shortage/surplus) of memory chips
surplus
