Chapter 03 – Demand, Supply, and Market Equilibrium (+ Appendix)
221. If market demand increases and market supply decreases, the change in equilibrium price
is unpredictable without first knowing the exact magnitudes of the demand and supply
changes.
222. A decrease in supply of X increases the equilibrium price of X, which reduces the
demand for X and automatically returns the price of X to its initial level.
223. In a competitive market, every consumer willing to pay the market price can buy a
product and every producer willing to sell the product at that price can sell it.
224. A price floor in a competitive market will result in persistent shortages of a product.
