Содержание слайда: Summary
Economists use the model of supply and demand to analyze competitive markets.
In a competitive market, there are many buyers and sellers, each of whom has little or no influence on the market price.
№52 слайд![Summary The demand curve](/documents_6/086eb1c17126ec6d158181604b718450/img51.jpg)
Содержание слайда: Summary
The demand curve shows how the quantity of a good depends upon the price.
According to the law of demand, as the price of a good falls, the quantity demanded rises. Therefore, the demand curve slopes downward.
In addition to price, other determinants of how much consumers want to buy include income, the prices of complements and substitutes, tastes, expectations, and the number of buyers.
If one of these factors changes, the demand curve shifts.
№53 слайд![Summary The supply curve](/documents_6/086eb1c17126ec6d158181604b718450/img52.jpg)
Содержание слайда: Summary
The supply curve shows how the quantity of a good supplied depends upon the price.
According to the law of supply, as the price of a good rises, the quantity supplied rises. Therefore, the supply curve slopes upward.
In addition to price, other determinants of how much producers want to sell include input prices, technology, expectations, and the number of sellers.
If one of these factors changes, the supply curve shifts.
№54 слайд![Summary Market equilibrium is](/documents_6/086eb1c17126ec6d158181604b718450/img53.jpg)
Содержание слайда: Summary
Market equilibrium is determined by the intersection of the supply and demand curves.
At the equilibrium price, the quantity demanded equals the quantity supplied.
The behavior of buyers and sellers naturally drives markets toward their equilibrium.
№55 слайд![Summary To analyze how any](/documents_6/086eb1c17126ec6d158181604b718450/img54.jpg)
Содержание слайда: Summary
To analyze how any event influences a market, we use the supply-and-demand diagram to examine how the even affects the equilibrium price and quantity.
In market economies, prices are the signals that guide economic decisions and thereby allocate resources.
