Rationing: Definition, Purposes, Historical Example

What Is Rationing?

Rationing is the practice of controlling the distribution of a good or service in order to cope with scarcity. Rationing is a mandate of the government, at the local or federal level. It can be undertaken in response to adverse weather conditions, trade or import/export restrictions, or, in more extreme cases, during a recession or a war.

Key Takeaways

  • Rationing is the limiting of goods or services that are in high demand and short supply.
  • It is often undertaken by governments as a way of mitigating the impact of scarcity and dealing with economic challenges.
  • Rationing risks generating black markets and unethical practices as people try to circumvent the austerity mandated by a ration.

How Rationing Works

Rationing involves the controlled distribution of a scarce good or service. An individual might be allotted a certain amount of food per week, for example, or households might be allowed to water their lawns only on certain days.

According to the law of supply and demand, when the available supply of a good or service falls below the quantity demanded, the equilibrium price rises, often to unaffordable levels. Rationing can artificially depress the price by putting constraints on demand.

Alternatively, price ceilings can be imposed; they risk the need for rationing in order to maintain a certain level of supply. In any case, rationing generally results in shortages. 

Rationing Example

The 1973 Arab oil embargo caused gasoline supplies in the U.S. to plummet, pushing up prices. The federal government responded by rationing domestic oil supplies to states, which in turn implemented systems to ration their limited stocks.

In some states, cars with license plates ending in odd numbers were only allowed to fill up on odd-numbered dates, for example, while cars with even numbered plates were only allowed to fill up on even-numbered days. These responses kept gas prices from spiking further but led to long lines.

Faced with the choice of allowing the prices of basic necessities to rise inexorably, or imposing rations, governments typically choose the latter; policymakers in such circumstances must choose among policies that are all difficult and risk some negative impact.

Special Considerations

Classical economic theory suggests that when demand exceeds supply, prices rise, and high prices, in turn, curtail demand and encourage new entrants to the market, increasing supply and bringing prices back down to reasonable levels. If the reality were this simple, rationing would be both counterproductive—because it creates shortages—and unnecessary, since the market will act to re-stabilize itself.

The problem is that for some goods and services—food, fuel, and medical care—demand is inelastic; that is, it does not fall in proportion to increases in price. Moreover, the entry of new suppliers to rebalance markets may not be possible if the shortage is the result of a crop failure, war, natural disaster, siege, or embargo. While not ideal, rationing is often undertaken by governments that would otherwise be facing an even bigger economic crisis.

Rationing to Combat Shortages

Many capitalist economies have temporarily resorted to rationing in order to cope with wartime or disaster-related shortages: the U.S. and Britain issued ration books during World War II, for example, limiting the quantities of tires, gasoline, sugar, meat, butter, and other goods that could be purchased.

In communist countries, by contrast, rationing was in many cases a permanent or semi-permanent feature of daily life. In Cuba in 2019, a ration book entitled an individual to small amounts of rice, beans, eggs, sugar, coffee, and cooking oil for the equivalent of a few cents in the United States.

Since that is not enough to survive, Cubans must purchase additional supplies on the open market, where the price of rice is around 20 times higher. Additionally, there are limits on the number of higher-quality items Cubans can purchase on the open market, such as chicken.

Cuba has implemented rationing as a way of mitigating the impact of an economic crisis; citizens are entitled to small amounts of basic food for almost no charge, while everything else is pricey and supplies are limited.

Risks of Rationing

Rationing provides governments with a way to constrain demand, regulate supply, and cap prices, but it does not totally neutralize the laws of supply and demand. Black markets often spring up when rationing is in effect. These allow people to trade rationed goods they may not want for ones they do.

Black markets also allow people to sell goods and services for prices that are more in line with demand, undermining the intent of rationing and price controls, but sometimes alleviating shortages.
