5. Qual é a equação de fornecimento?
Custo
Custo= P = f(Qs) P = 2 + .5Qs or Qs = -4 + 2P
6. Construa a equação de suprimento no gráfico e complete o cronograma na Tabela. Usando o gráfico, qual é o preço de equilíbrio aproximado?
About $7.40
8. Usando o gráfico qual é a quantidade de equilíbrio aproximada?
About 10.8 units
Basic Microeconomics - Demand, Supply and Equilibrium
---------------------------------------------------------------
supply decreases?
Demand & Supply
9.What is the equilibrium quantity and price when calculated by using the supply and demand equations?
[pic 2][pic 3][pic 4][pic 5][pic 6]
Quantity supplied = Quantity demanded
Qs = -4 + 2P = 20 – 1.25P = Qd 3.25P = 24
P = 24/3.25 = $7.385 (equilibrium Price)
2 +.5Q = 16 - .8Q
1.3Q = 14
Q = 14/1.3 = 10.769 units
10.What happens if the demand should increase (decrease)? More is purchased at each
possible price; A higher price will be paid for each unit of the good. .
Show an increase (decrease) in demand on the graph? See “Demand Increase”
in Figure 1.
11. What happens to equilibrium price and quantity when demand increases (decreases)?
Both equilibrium price and quantity would increase (decrease)
12. Show a decrease (increase) in supply. See
[pic 7][pic 8][pic 9]
“Supply Decrease” in Figure 1
13.What happens to equilibrium price and quantity when the supply decreases? Equilibrium
price will increase while equilibrium quantity will decrease.
14. What happens when demand increases and
Equilibrium price must
necessarily increase but the change in equilibrium quantity will depend on the magnitude of the shifts and the relative elasticities of supply and demand.
The supply and demand functions intersect between these two rows, the “quantity supplied” will equal the “quantity demanded”
