Term
law of demand
Definition
the principle that there is an inverse relationship between the price of the good and the quantity buyers are willing to purchase ceteris paribus
Term
demand curve
Definition
is formed by the line connecting the possible prices and quantities purchased. You can find the quantity demanded at any price by moving along the curve
Term
demand
Definition
demand is a curve or schedule showing the various quantities of a product consumers are willing to purchase at possible prices during a specified period of time ceteris paribus
Term
change in quantity demanded
Definition
a movement between points along a stationary demand curve ceteris paribus
results solely from change in the price
Term
nonprice determinants of demand
Definition
factors that aren't the price but that influence the position of the demand curve
number of buyers, tastes and preferences, income, expectations of future changes in prices income and availability of goods, prices of related goods
Term
on a demand curve graph a decrease in prices causes
Definition
an increase in the quantity demanded (movement along the demand curve)
Term
on a demand curve graph a change in a nonprice determinant causes
Definition
an increase in demand (shifting the demand curve)
Term
normal good
Definition
any good for which there is a direct relationship between changes in income and its demand curve
Term
inferior good
Definition
any good for which there is an inverse relationship between changes in income and its demand curve
Term
substitute good
Definition
a good that competes with another good for consumer purchase. as a result there is a direct relationship between a price change for one good and the demand for its competitor good
Term
complementary good
Definition
a good that is jointly consumed with another good. as a result there is an inverse relationship between the price change for one good and the demand for the go together good
Term
law of supply
Definition
the relationship between ranges of possible prices and quantities supplied
the principle that there is a direct relationship between the price of a good and the quantity sellers are willing to offer for sale in a defined time period ceteris paribus
Term
supply
Definition
a curve or schedule showing the various quantities of a product sellers are willing to produce and offer for sale at possible prices during a specific time, ceteris paribus
Term
change in quantity supplied
Definition
a movement between points along a stationary supply curve, ceteris paribus
Term
change in supply
Definition
an increase or a decrease in the quantity supplied at each possible price. An increase in supply is a rightward shift in the entire supply curve. A decrease in supply is a leftward shift in the entire supply curve
Term
on a supply curve graph an increase in price leads to what
Definition
an increase in quantity supplied, a shift on the supply curve
Term
on a supply curve graph a change in nonprice determinants leads to what
Definition
an increase in supply, a shift of the supply curve
Term
nonprice determinants of supply
Definition
number of sellers, technology, resource prices (price of the resources used), taxes and subsidies, expectations of producers, prices of other goods the firm could produce
Term
market
Definition
any arrangement in which buyers and sellers interact to determine the price and quantity of goods and services exchanged
Term
surplus
Definition
a market condition existing at any price where the quantity supplied is greater than the quantity demanded
Term
shortage
Definition
a market condition existing at any price where the quantity supplied is less than the quantity demanded
Term
equilibrium
Definition
a market condition that occurs at any price and quantity where the quantity demanded and the quantity supplied are equal
Term
price system
Definition
a mechanism that uses the forces of supply and demand to create an equilibrium through rising and falling prices
Term
what states that there is an inverse relationship between the price and the quantity demanded ceteris paribus
Definition
law of demand
Term
a movement along a stationary demand curve caused by a change in price is called a
Definition
change in quantity demanded
Term
this is a good consumers buy more of when their income increases
Definition
a normal good
Term
this states that there is a direct relationship between the price and the quantity supplied, ceteris paribus
Definition
law of supply
Term
a movement along a stationary supply curve in response to a change in price is called a
Definition
change in quantity supplied
Term
when the price of a good is greater than the equilibrium price there is an exvess quantity supplied called a
Definition
surplus
Term
the unique price and quantity established at the intersection of the supply and demand curve is called
Definition
equilibrium
Term
this is the supply and demand mechanism which establishes equilibrium through the ability of prices to rise and fall
Definition
price system
Term
this is something that has an inverse relationship between changes in income and its demand curve
Definition
inferior good
Term
this competes with another good for consumer purchases. As a result there is a direct relationship between price change for one good and the demand for its competitor good
Definition
substitute
Term
the principle that there is a direct relationship between the price of a good and the quantity sellers are willing to offer for sale in a defined time period, ceteris paribus
Definition
law of supply
Term
any arrangement in which buyers and sellers interact to determine the price and quantity of goods and services exchanged
Definition
the market
Term
this is jointly consumed with another good. as a result there is an inverse relationship between a price change for one good and the demand for its go together good
Definition
complementary good
Term
a market condition existing at any price where the quantity supplied is less than the quantity demanded
Definition
shortage
