  2. 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 ...

  3. 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 ...

  4. Income elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Income_elasticity_of_demand

    In economics, the income elasticity of demand ( YED) is the responsivenesses of the quantity demanded for a good to a change in consumer income. It is measured as the ratio of the percentage change in quantity demanded to the percentage change in income. For example, if in response to a 10% increase in income, quantity demanded for a good or ...

  6. Demand curve - Wikipedia

    en.wikipedia.org/wiki/Demand_curve

    The shift from D1 to D2 means an increase in demand with consequences for the other variables. A demand curve is a graph depicting the inverse demand function, [1] a relationship between the price of a certain commodity (the y -axis) and the quantity of that commodity that is demanded at that price (the x -axis).

  7. Demand - Wikipedia

    en.wikipedia.org/wiki/Demand

    The price elasticity of demand is a measure of the sensitivity of the quantity variable, Q, to changes in the price variable, P. It shows the percent by which the quantity demanded will change as a result of a given percentage change in the price. Thus, a demand elasticity of -2 says that the quantity demanded will fall 2% if the price rises 1%.

  8. Cross elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Cross_elasticity_of_demand

    The cross elasticity of demand is calculated as the ratio between the percentage change of the quantity demanded for a good and the percentage change in the price of another good, ceteris paribus: [1] The sign of the cross elasticity indicates the relationship between two goods. A negative cross elasticity denotes two products that are ...
