Computing the Price Elasticity of Demand:
Percentage change in price (FORMULA)
The Midpoint Method: A Better Way to Calculate Percentage Changes and Elasticities:
(P2 P1 ) / [(P2 P1 ) / 2] (FORMULA)
The Variety of Demand Curves:
Demand is considered elastic when the elasticity is greater than 1
If the elasticity is exactly 1, the quantity moves the same amount proportionately as the price
Total Revenue and the Price Elasticity of Demand:
Total revenue- the amount paid by buyers and received by sellers of a good, computed as the price elasticity of demand rise of the good times the quantity sold
Elasticity and Total Revenue along a Linear Demand Curve:
(In a demanding schedule) The slope of a linear demand curve is constant, but its elasticity is not.
Other Demand Elasticities:
The Price Elasticity of Supply and Its Determinants:
Computing the Price Elasticity of Supply:
Percentage change in price
The Variety of Supply Curves:
In some markets, the elasticity of supply is not constant
Can Good News for Farming Be Bad News for Farmers?:
In one scenario, you are a farmer who recently heard about a new discovery that raises the amount farmers can produce from each acre of land by 20 percent.
Why Did OPEC Fail to Keep the Price of Oil High?:
Oil was the cause of the most disruptive events in the world’s economy
The Organization of Petroleum Exporting Countries (OPEC) decided to raise the world price of oil to increase their incomes.
They’ve come to the conclusion that OPEC’s coordinated reduction in supply
proved less profitable in the long run. The cartel learned that raising prices is easier in the short run than in the long run.
Does Drug Interdiction Increase or Decrease Drug-Related Crime?:
Illegal drugs such as heroin, cocaine, ecstasy, and crack are followed by consequences
The U.S. government has spent billions of dollars each year to discourage the use of illegal drugs
Though the purpose of drug interdiction is meant to reduce the use of drugs, it mainly impacts the buyers rather than the sellers
