Pricing is a difficult-to-detect and prove manipulation system, as many companies with identical prices are not sufficient to prove that they have worked together to set prices. For example, the price of raw materials such as wheat is almost always the same in different markets in the same region. Because the products are virtually identical, the demand and supply factors for a farm most likely affect all other farms growing the same product in the same geographic area. Economic liberals believe that price-fixing is a voluntary and consensual activity between the parties, which should be free from state coercion and state interference. Sometimes pricing ensures a stable market for both consumers and producers. Any short-term benefit of increased price competition will help to drives some producers out of the market and increase bottlenecks and prices for consumers. At the end of the day, pricing legislation forces producers in a market because they cannot compete with the biggest discount and the market dissolves a monopoly anyway.  While stable prices generally mean that sellers agree on price, it may also include agreements among buyers to determine the price at which they will buy products. Freezing or lowering prices: governments set prices by imposing price stops. In the 1970s, inflation threatened to destroy consumer confidence in the economy itself. The government has set prices to stop inflation and restore confidence.
It is a very clumsy instrument and it is only used if monetary policy has proved ineffective. Price fixing, any agreement between competitors (“horizontal”) or between producers, wholesalers and retailers (“verticals”) to raise, set or maintain prices. Many, but not all, price agreements are illegal in terms of cartels or competition. Illegal acts may be prosecuted by public or civilian prison officers or by private parties who have suffered economic damage as a result of their behaviour. Under U.S. law, price exchanges between competitors may also violate cartel law. These include the exchange of prices with the intention of setting prices or the exchange rate which affects the prices set by individual competitors. Evidence that competitors have common prices can be relied upon as evidence of an illegal price agreement.  In general, experts advise that competitors avoid agreeing on the price.  Vertical price agreements are held in the production and distribution supply chain between producers, wholesalers and retailers. When producers meet to set minimum prices for the resale price, this is a resale price. In this case, manufacturers may agree not to trade with retailers that offer their products at a discount or discount.
Setting minimum prices for resale is inherently illegal in the United States. Distributors may also agree to set TV prices at a reduced price.
