Allocation mechanisms are the means used to distribute scarce goods and resources.Common allocation mechanisms are first-come, first-served; government;random; and the market system.
The outcome of an exchange system is evaluated on the basis of efficiency.An efficient allocation of resources is one in which resources are allocated so that no one can be made better off without
The price or market system is relied on for most exchanges because it is generally the most efficient. It creates incentives that lead to growth and improvements in standards of living.
A market need not be a specific location. A market exists when buyers and sellers interact to buy and sell a specific product.
The market process refers to the buying and selling of a good and the resulting allocation of resources to their highest-valued uses.
According to the law of demand, as the price of any good or service rises(falls), the quantity demanded of that good or service falls (rises) during a specific period of time, everything else held
A demand schedule is a listing of the quantity demanded at each price.
The demand curve is a downward-sloping line plotted using the values of the demand schedule.
Market demand is the sum of all individual demands.
Demand changes when one of the determinants of demand changes. A demand change is a shift of the demand curve.
The quantity demanded changes when the price of the good or service changes. This is a change from one point on the demand curve to another point on the same demand curve.
The determinants of demand are income, tastes, prices of related goods and services, expectations, and number of buyers.
According to the law of supply, the quantity supplied of any good or service is directly related to the price of the good or service, during a specific period of time, everything else held constant.
Market supply is found by adding together the quantities supplied at each price by every producer in the market.
Supply changes if prices of relevant resources change, if technology or productivity changes, if producers’ expectations change, if the number of producers changes, or if prices of related goods
Changes in supply are reflected in shifts of the supply curve. Changes in the quantity supplied are reflected in movements along the supply curve.
Equilibrium occurs when the quantity demanded and the quantity supplied are equal: it is the price-quantity combination where the demand and supply curves intersect.
A price that is above the equilibrium price creates a surplus. Producers are willing and able to offer more for sale than buyers are willing and able to purchase.
A price that is below the equilibrium price leads to a shortage. Buyers are willing and able to purchase more than producers are willing and able to offer for sale.
When demand changes, price and quantity change in the same direction.Both rise as demand increases and both fall as demand decreases.
When supply changes, price and quantity change but not in the same direction.When supply increases, price falls and quantity rises. When supply decreases, price rises and quantity falls.
Using the following schedule, define the equilibrium price and quantity. Plot the demand and supply curves and show the equilibrium price and quantity.Quantity Quantity Price Demanded Supplied$ 1 500
