Document Summary

Both supply and demand for oil are relatively inelastic in the short-run. An organization of 14 oil-exporting countries, who account for an estimated 43% of oil exports in the world. Recently, they had put a price floor on the price of oil due to it continuously declining. Consider the policies that directly control prices. Price ceiling: a legal maximum on the price of which a good can be sold. Price floor: a legal minimum on the price at which a good can be sold. Two outcomes are possible for a price ceiling, 1. the price ceiling is not binding on the market and the market price will be lower than the equilibrium price. The price ceiling is a binding constraint on the market and the market price will equal the price ceiling. Causes a permanent shortage of the good in the marketplace. Can"t get to equilibrium if there is a binding price ceiling.
