demand Flashcards
what is a market
something that brings buyers and sellers together
demand
the amount of a good or service buyers are willing and able to purchase
demand schedule
is a table that lists the quantity of a good that consumers in a market will buy at a given price
demand curve
a graph that shows the quantity demanded at a given price
market demand
is the sum of quantities demanded by all consumers in a market
law of demand
an increase in price will cause a decrease in quantity demanded and vice versa
the law of diminishing the marginal utility
why the demand curve is downward sloping
- each additional unit of a good or service that is consumed brings less satisfaction
demand determinants (changes in demand)
- the number of buyers in the market
- income (normal products- income increase causes a rightward shift but causes a leftward shift for inferior products such as second-hand goods)
- price of other products
- consumer preferences (a new trend)
- consumer expectations (if they expect a price to go down for a specific item)
difference between a substitute and complementary products
both fall under the determinant for the price of products,
however:
substitute products: products that can be substituted for another, example butter and margarine
complementary products: products that go hand in hand, example printers and ink
supply
willing to sell at various prices
supply schedule and supply curve
same as demand schedule and demand curve, however, a supply curve moves from bottom left to top right
law of supply
an increase in price will increase the quantity supplied (Qs) and vice versa
supply determinants
- the number of producers
- resource prices
- improvement/disimprovement in technology
- changes in nature
- prices of related products
- producer expectations
equilibrium
the point where supply curve and demand curve intersetc
surplus
there is excess supply and price is pushed down
