While competition law has not accepted these arguments, a number of lawmakers and public and local regulators have put in place systems that allow, for example, competing healthcare providers to seek permission to set their prices under close state supervision in order to subsidize low-cost care for the poor. These systems protect suppliers from lawsuits by extending state immunity from antitrust enforcement to their private acts. A: A uniform and simultaneous variation in prices could result from price cartels, but it could also be the result of independent commercial reactions under the same market conditions. For example, if international oil market conditions lead to an increase in the price of crude oil, this could lead to an increase in the wholesale price of gasoline. Where producers enter into agreements to set minimum resale prices, this is a resale price fixing. In this case, manufacturers may agree not to negotiate with retailers who offer their products at a discount or discount. Setting minimum prices for resale is inherently illegal in the United States. Not all price similarities or price changes that occur at the same time are the result of price cartels. On the contrary, they are often the result of normal market conditions. For example, the prices of raw materials such as wheat are often identical, because the products are virtually identical and the prices charged by farmers all go up and down together without agreement between them.
If a drought leads to a decrease in the supply of wheat, the price of all farmers involved increases.
