  2. Price controls - Wikipedia

    en.wikipedia.org/wiki/Price_controls

    A price floor is a government- or group-imposed price control or limit on how low a price can be charged for a product, [21] good, commodity, or service. A price floor must be higher than the equilibrium price in order to be effective. The equilibrium price, commonly called the "market price", is the price where economic forces such as supply ...

  3. Cobweb model - Wikipedia

    en.wikipedia.org/wiki/Cobweb_model

    The equilibrium price is at the intersection of the supply and demand curves. A poor harvest in period 1 means supply falls to Q 1, so that prices rise to P 1. If producers plan their period 2 production under the expectation that this high price will continue, then the period 2 supply will be higher, at Q 2.

  4. Arrow–Debreu model - Wikipedia

    en.wikipedia.org/wiki/Arrow–Debreu_model

    In mathematical economics, the Arrow–Debreu model is a theoretical general equilibrium model. It posits that under certain economic assumptions (convex preferences, perfect competition, and demand independence), there must be a set of prices such that aggregate supplies will equal aggregate demands for every commodity in the economy.

  5. Market equilibrium computation - Wikipedia

    en.wikipedia.org/wiki/Market_equilibrium_computation

    Market equilibrium computation (also called competitive equilibrium computation or clearing-prices computation) is a computational problem in the intersection of economics and computer science. The input to this problem is a market , consisting of a set of resources and a set of agents .

  6. Market clearing - Wikipedia

    en.wikipedia.org/wiki/Market_clearing

    A market-clearing price is the price of a good or service at which the quantity supplied equals the quantity demanded, also called the equilibrium price. [2] The theory claims that markets tend to move toward this price. Supply is fixed for a one-time sale of goods, so the market-clearing price is simply the maximum price at which all items can ...

  7. Supply and demand - Wikipedia

    en.wikipedia.org/wiki/Supply_and_demand

    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 ...

  8. Economic equilibrium - Wikipedia

    en.wikipedia.org/wiki/Economic_equilibrium

    This will tend to put downward pressure on the price to make it return to equilibrium. Likewise where the price is below the equilibrium point (also known as the "sweet spot" [3]) there is a shortage in supply leading to an increase in prices back to equilibrium. Not all equilibria are "stable" in the sense of equilibrium property P3.

  9. Competitive equilibrium - Wikipedia

    en.wikipedia.org/wiki/Competitive_equilibrium

    On the other hand, any price below 10 is not an equilibrium price because there is an excess demand (both Alice and Bob want the car at that price), and any price above 20 is not an equilibrium price because there is an excess supply (neither Alice nor Bob want the car at that price). This example is a special case of a double auction.
