The alleged economic relief from controlled gas prices has also been offset by new spending. Some petrol stations have tried to compensate for the loss of revenue by making formerly optional services such as windshield washing a mandatory part of refuelling and charging a fee for it. The great advantage of a price cap is, of course, the limitation of costs for the consumer. This keeps things affordable and prevents price reductions or producers/suppliers from exploiting them unfairly. If it is only a temporary shortage leading to runaway inflation, caps can ease the pain of rising prices until supply returns to normal levels. Price caps can also stimulate demand and encourage spending. Example: Suppose supply and demand are linear, where the quantity delivered is equal to the price and the quantity demanded is equal to a price minus. In this case, the equilibrium price and the equilibrium quantity are both 1/2. A floor price of p > 1/2 induces a quantity requested of 1 – p.
How many units will suppliers offer if a supplier`s business opportunity is random? Suppose that q ≥ 1 – p units are offered. The opportunity to sell a supplier is 1−p q. Thus, the border supplier (who, assuming, has a marginal price of q) has a probability of gaining 1−p q, p, and a certainty of paying q. Exactly q units are delivered if it is a break-even proposition for the marginal supplier, i.e. 1−p q p−q=0 or q= p(1−p). The following video explores the impact of price caps. Speakers identify five main consequences: This episode of our Economic Lowdown podcast series answers a crucial economic question: Where do prices come from? Listeners discover that supply and demand work together as the two scissor blades to determine the balance of the market – and the prices of the things you buy. In the short term, price caps have their advantages. However, they can become a problem if they last too long or if they are too below the market equilibrium price (if the quantity requested is equal to the quantity delivered). Figure 5.5 “A floor price” shows the floor price with a horizontal line and is above the equilibrium price.
Therefore, a larger quantity is delivered in the floor price than requested, which leads to a surplus. There are units that are socially efficient to trade, but are not traded – because their value is below the floor price. The commercial profits associated with these units, which are lost due to the floor price, represent the windfall effect. The theory of floor and ceiling prices can be easily articulated with a simple analysis of supply and demand. Consider a lower price limit – a legal minimum price. If the floor price is low enough – below the equilibrium price – there is no effect, because the same forces that tend to induce a price that corresponds to the equilibrium price continue to function. If the floor price is higher than the equilibrium price, there will be a surplus because at the floor price, more units are delivered than what is requested. This surplus is illustrated in Figure 5.5 “A Floor Price”. There are several cases of government-imposed price caps, usually for goods considered essential or necessary. Below are some common examples of price caps. A minimum wage is a well-known type of floor price. Based on the principle that a person who works full-time should earn enough to be able to afford a basic standard of living, it sets the lowest legal amount that a job can pay.
An important and undesirable by-product of price caps is discrimination. In a free or unfettered market, discrimination against a particular group based on race, religion or other factors requires transactions based not on price but on another factor. In a free market, therefore, discrimination is costly – discrimination means, for example, that an apartment is not rented to the highest bidder, but to the highest bidder of the preferred group. On the other hand, with a price cap, there is a shortage; and sellers can discriminate at a lower cost or even for free. In other words, if there are twice as many people looking for apartments as there are price-capped apartments, landlords can “choose and choose” from potential tenants while receiving the maximum legal rent. Thus, a price cap has the undesirable by-product of reducing the cost of discrimination. The supply and demand model shows how people and businesses will respond to the incentives offered by price control laws in a way that often leads to undesirable consequences. Other policy instruments can often achieve the desired objectives of price control laws while avoiding at least some of their equal costs and trade-offs. If this is the case, demand can skyrocket, leading to supply shortages. Even if the prices that producers are allowed to charge are too different from their production costs and professional expenses, something must be given.
You may need to cut corners, reduce quality, or charge higher prices for other products. They may have to stop bids or not produce as much (resulting in more bottlenecks). Some may be forced to close their doors if they cannot make a reasonable profit from their goods and services. A price cap is essentially a kind of price control. Price caps can be advantageous so that the essentials are affordable, at least temporarily. Economists, however, doubt the benefit of these caps in the long run. A price cap is the prescribed maximum amount a seller can charge for a product or service. Usually set by law, price caps are usually applied to staple foods such as food and energy products when these products become unaffordable for ordinary consumers. Economists believe that there are a small number of basic principles that explain how economic actors react in different situations. Two of these principles that we have already introduced are the laws of supply and demand. Governments can enact laws that affect market outcomes, but no law can deny these economic principles.
On the contrary, the laws of supply and demand often become clear sometimes unexpectedly, which can undermine the intent of government policy. This is one of the main conclusions of this section. A price cap is a maximum price. Analogous to a low floor price, a price ceiling higher than the equilibrium price has no effect. Tell me that I can`t charge more than a billion dollars for this book (which will be given away for free), and it won`t affect the price charged or the amount exchanged. Therefore, the important case of a price cap is one that is lower than the equilibrium price. Caps on prescription drugs and laboratory tests are another example of a common price cap. In addition, insurance companies often set caps on the amount they reimburse a doctor for a procedure, treatment, or office visit. A broader and more theoretical objection to price caps is that they create a windfall effect for society.
This describes an economic deficiency caused by an inefficient allocation of resources that disrupts the equilibrium of a market and contributes to making it less efficient. A price cap is a legal maximum price you pay for a good or service. A government sets price caps to keep the price of certain necessary goods or services affordable. For example, the price of bottled water exceeded $5 per gallon in 2005 during Hurricane Katrina.
