A price ceiling is a government- or group-imposed price control, or limit, on how high a price is charged for a product, commodity, or service.Governments use price ceilings to protect consumers from conditions that could make commodities prohibitively expensive.
In the first graph at right, the dashed green line represents a price floor set below the free-market price. In this case, the floor has no practical effect. The government has mandated a minimum price, but the market already bears and is using a higher price. An effective, binding price floor, causing a surplus (supply exceeds demand)
The effective price to the sellers is again lower by the amount of the tax and they will supply the good as if the price were lower by the amount of tax. Last, the total impact of the tax can be observed. The equilibrium price of the good rises and the equilibrium quantity decreases.
Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...
A related government intervention to price floor, which is also a price control, is the price ceiling; it sets the maximum price that can legally be charged for a good or service, with a common example being rent control. A price ceiling is a price control, or limit, on how high a price is charged for a product, commodity, or service.
A common and specific example is the supply-and-demand graph shown at right. This graph shows supply and demand as opposing curves, and the intersection between those curves determines the equilibrium price. An alteration of either supply or demand is shown by displacing the curve to either the left (a decrease in quantity demanded or supplied ...
More loosely, "rent control" describes several types of price control: "strict price ceilings", also known as "rent freeze" systems, or "absolute" or "first generation" rent controls, in which no increases in rent are allowed at all (rent is typically frozen at the rate existing when the law was enacted);
An OHLC chart, with a moving average and Bollinger bands superimposed. An open-high-low-close chart (OHLC) is a type of chart typically used in technical analysis to illustrate movements in the price of a financial instrument over time. Each vertical line on the chart shows the price range (the highest and lowest prices) over one unit of time ...
