Floor function. Ceiling function. In mathematics, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted ⌊x⌋ or floor (x). Similarly, the ceiling function maps x to the smallest integer greater than or equal to x, denoted ⌈x⌉ or ceil (x).
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 price floor is a government- or group-imposed price control or limit on how low a price can be charged for a product, [1] good, commodity, or service. It is one type of price support; other types include supply regulation and guarantee government purchase price. A price floor must be higher than the equilibrium price in order to be effective.
Interest rate cap and floor. In finance, an interest rate cap is a type of interest rate derivative in which the buyer receives payments at the end of each period in which the interest rate exceeds the agreed strike price. An example of a cap would be an agreement to receive a payment for each month the LIBOR rate exceeds 2.5%.
Deadweight loss. In economics, deadweight loss is the loss of societal economic welfare due to production/consumption of a good at a quantity where marginal benefit (to society) does not equal marginal cost (to society) – in other words, there are either goods being produced despite the cost of doing so being larger than the benefit, or ...
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. Such conditions can occur during periods of high inflation, in the event of an ...
In economics, a price support may be either a subsidy, a production quota, or a price floor, each with the intended effect of keeping the market price of a good higher than the competitive equilibrium level. In the case of a price control, a price support is the minimum legal price a seller may charge, typically placed above equilibrium.
The point of total assumption ( PTA) is a point on the cost line of the profit-cost curve determined by the contract elements associated with a fixed price plus incentive-Firm Target (FPI) contract above which the seller effectively bears all the costs of a cost overrun. The seller bears all of the cost risk at PTA and beyond, due to a dollar ...
