  2. Law of demand - Wikipedia

    en.wikipedia.org/wiki/Law_of_demand

    The law of demand is represented by a graph called the demand curve, with quantity demanded on the x-axis and price on the y-axis. Demand curves are downward sloping by definition of the law of demand. The law of demand also works together with the law of supply to determine the efficient allocation of resources in an economy through the ...

  3. Price elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_demand

    The price elasticity gives the percentage change in quantity demanded when there is a one percent increase in price, holding everything else constant. If the elasticity is −2, that means a one percent price rise leads to a two percent decline in quantity demanded. Other elasticities measure how the quantity demanded changes with other ...

  4. Small but significant and non-transitory increase in price

    en.wikipedia.org/wiki/Small_but_significant_and...

    e. In competition law, before deciding whether companies have significant market power which would justify government intervention, the test of small but significant and non-transitory increase in price (SSNIP) is used to define the relevant market in a consistent way. It is an alternative to ad hoc determination of the relevant market by ...

  5. Elasticity (economics) - Wikipedia

    en.wikipedia.org/wiki/Elasticity_(economics)

    In economics, elasticity measures the responsiveness of one economic variable to a change in another. [1] If the price elasticity of the demand of something is -2, a 10% increase in price causes the quantity demanded to fall by 20%. Elasticity in economics provides an understanding of changes in the behavior of the buyers and sellers with price ...

  6. Supply and demand - Wikipedia

    en.wikipedia.org/wiki/Supply_and_demand

    Otherwise stated, producers will be willing to supply more wheat at every price and this shifts the supply curve S 1 outward, to S 2 —an increase in supply. This increase in supply causes the equilibrium price to decrease from P 1 to P 2. The equilibrium quantity increases from Q 1 to Q 2 as consumers move along the demand curve to the new ...

  7. Demand - Wikipedia

    en.wikipedia.org/wiki/Demand

    For example, if the price of a gallon of milk were to rise from $5 to a price of $15, that would be a big price increase. Such a significant price increase causes the consumer to demand less of that product at the price of $15 because not only is it more expensive, but the new price is very unreasonable for a gallon of milk. Price of related ...

  8. Price level - Wikipedia

    en.wikipedia.org/wiki/Price_level

    e. The general price level is a hypothetical measure of overall prices for some set of goods and services (the consumer basket ), in an economy or monetary union during a given interval (generally one day), normalized relative to some base set. Typically, the general price level is approximated with a daily price index, normally the Daily CPI.

  9. Utility ratemaking - Wikipedia

    en.wikipedia.org/wiki/Utility_ratemaking

    The purpose of performance-based regulation is to reduce the negative impact of information asymmetries and to motivate regulated companies to reduce their costs in order to increase profit. Usually, this is done by setting a cap on prices or revenues. A general formula is: P(t) = (1 + RPI - X) . P(t-1) where P(t) is the price in time t.
