News articles say that the Israelis are “cheesed off” and “curdled.” Angered by the soaring price of cottage cheese, a Facebook consumer group of 70,000 friends has agreed to stop buying it on July 1. The headline on the boycott page said, “Let it stay in the stores and spoil until the price comes down.”

This “tempest in a tub” began when cottage cheese price caps were removed. You can guess the result. The price of a 250 gram (9 ounce) container soared from 4.82 to 8 shekels ($2.30).  A national breakfast staple, Israeli cottage cheese (just like Coca-Cola) has a secret small curd formula.

The Israeli Facebook group appears to want a cottage cheese price cap.

The Economics Lesson

During the early 1970s, to control inflation, U.S. President Richard Nixon implemented wage and price controls. Like taking the cover off a pressure cooker, when the controls were lifted, prices immediately jumped.

As economists, we can explain why with a demand and supply graph. With the demand curve sloping downward, the supply curve sloping upward, the Y-axis price and the X-axis quantity, the curves meet at an equilibrium price and quantity. The market pushes toward equilibrium. Above equilibrium? There is a surplus. Below equilibrium? There is a shortage.

An Economic Question: Why are price controls called a ceiling?

Our story begins during February when Russian Prime Minister Putin decided to freeze gasoline prices. Oil companies had a predictable response.

They left.

Following the money, they redirected their supply to higher prices elsewhere. The result? Russian gasoline exports were 40% higher than last year at the same time.

A second result? The Russians (almost) ran dry.

So now, the Prime Minister is banning exports during May for “high octane petrol sold at the highest prices.” Also, he is upping export duties and cutting local sales taxes.

The Economic Lesson

Demand and supply graphs continue the story. With price our Y-axis and quantity the X-axis, draw an “X” as the lines on your graph. The downward sloping line is demand and the upward sloping line is supply. Next draw a horizontal line below equilibrium, the point where the demand and supply lines meet. This line, called a ceiling (because it stops prices from rising), illustrates why we get a shortage. The distance between the point that the ceiling crosses supply and the point that the ceiling crosses demand represents the size of the shortage. A shortage is precisely what Mr. Putin created.

Now with export taxes, he is making supply more expensive. Then, typically, the supply curve shifts to the left and upward. And producers decide to supply less.

An Economic Question: The Prime Minister’s goal is to make consumers happy. Will he be successful? Hint: Think about price and quantity.
