what does it mean to say that we are running out of "cheap oil"?
that oil reserves are becoming more expensive to find and extract over time. this means the supply will eventually decrease, which will increase the price.

normal good
for a normal good, an increase in income causes the demand curve to shift to the right (holding the goods price fixed), or in other words, causes consumers to buy more or the good
inferior good
for an inferior good, an increase in income causes the demand curve to shift to the left (holding the goods price fixed), or in other words, causes buyers to buy less of the good.
For a trade to take place, a buyer's willingness must be _________.

the process of adding up individual behaviors
demand curves are

horizontal curve.
market price
if all sellers and all buyers face the same price
negatively related

rises, upwards sloping.
the market supply curve is the ______ of all the supply curves of potential producers and would be graphed to the _________ of the individual curves.
sum, right.
the concept of diminishing marginal benefits states that
the more you consume of a good, your willingness to pay for an additional unit declines.
perfectly competitive market
1. sellers all sell an identical good or service 2. any individual buyer or any individual seller isn't powerful enough on his or her own to affect the market price of that good or service
if the number of sellers of sparkling wine decreases significantly, then the supply curve for sparkling wine would ________.
decrease (shift left)
movement along the demand curve
if a good's own price changes and its demand curve hasn't shifted, the own price change produces a movement along the demand curve.
Law of Demand
in almost all cases, the quantity demanded rises when the price falls (holding all else equal)
Law of Supply
in almost all cases, the quantity supplied rises when the price rises (holding all else equal)
does the shape of the market curve differ from the shape of an individual demand curve?
no, they both tend to be downward sloping curves
Does the shape of the market demand curve differ from the shape of an individual demand curve?
no, they both tend to be downward sloping.
We make the assumption of holding all else equal when considering demand curves since we want to focus on the changes in the quantity demanded that result from changes in
only the price of the good.
demand curve
plots the quantity demanded at different prices
supply curve
plots the quantity supplied at different prices.
a supply curve has a ______ slope due to the lae of supply. the law of supply states that supplies _______ as price increases.
positive, increae
A supply curve has a ________ slope due to the law of supply. the law of supply states that supplies __________ as price increases.
positive, increase.
quantity supplied
the amount of a good or service that sellers are willing to sell at a given price
quantity demanded
the amount of a good that buyers are willing and able to purchase at a give price
competitive equilibrium
the crossing point of the supply curve and the demand curve

market supply curve
the market supply curve is the sum of the individual supply curves of all the potential sellers. it plots the relationship between the total quantity supplied and the market price, holding all else equal.
excess demand
when the market price is below the competitive equilibrium price, quantity demanded exceeds quantity supplied

decrease (shift left)

decrease (shift left)
what is meant by holding all else equal, and how is this concept used when discussing movements along the demand curve?
all variables that can affect the demand for the good are held constant.

demand curve shifts
The demand curve shifts when the quantity demanded changes at a given price
complements
