The own-price elasticity of demand for apples is -1.2. If the price of apples falls by 5%, what will happen to the quantity of apples demanded?
  • It will increase 6%

The demand for good X has been estimated by QX d =12 – 3PX + 4PY. Suppose that good X sells at $2 per unit and good Y sells for $1 per unit. Calculate the own price elasticity.

Consider a market characterized by the following demand and supply conditions: PX = 50 – 5QX and PX = 32 + QX. The equilibrium price and quantity are, respectively,
  • $35 and 3 units.
Consider a market characterized by the following demand and supply conditions: PX = 15 – 2QX and PX = 3 + 2QX. The equilibrium price and quantity are, respectively,
  • $9 and 3 units.
In a competitive market, the market demand is Qd = 60 – 6P and the market supply is Qs = 4P. A price floor of $9 will result in a
  • surplus of 30 units.
Consider a market characterized by the following inverse demand and supply functions: PX = 10 – 2QX and PX = 2 + 2QX. Compute the loss in social welfare when an $8 per unit price floor is imposed on the market.
