  2. Price elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_demand

    When the price elasticity of demand is unit (or unitary) elastic (E d = −1), the percentage change in quantity demanded is equal to that in price, so a change in price will not affect total revenue. When the price elasticity of demand is relatively elastic (−∞ < E d < −1), the percentage change in quantity demanded is greater than that ...

  3. Elasticity (economics) - Wikipedia

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

    Like Price Elasticity of Demand, time also affects Price Elasticity of Supply. Though, there are other varying factors that affect this too, such as: capacity, availability of raw materials, flexibility, and the number of competitors in the market. Though, the time horizon is arguably the most influential detriment to price elasticity of supply ...

  4. 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%.

  5. Demand curve - Wikipedia

    en.wikipedia.org/wiki/Demand_curve

    The elasticity of demand indicates how sensitive the demand for a good is to a price change. If the elasticity's absolute value is between zero and 1, demand is said to be inelastic; if it equals 1, demand is "unitary elastic"; if it is greater than 1, demand is elastic. A small value--- inelastic demand--- implies that changes in price have ...

  6. Cross elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Cross_elasticity_of_demand

    In economics, the cross (or cross-price) elasticity of demand (XED) measures the effect of changes in the price of one good on the quantity demanded of another good. This reflects the fact that the quantity demanded of good is dependent on not only its own price (price elasticity of demand) but also the price of other "related" good.

  7. Lerner index - Wikipedia

    en.wikipedia.org/wiki/Lerner_Index

    The index ranges from 0 to 1. A perfectly competitive firm charges P = MC, L = 0; such a firm has no market power. An oligopolist or monopolist charges P > MC, so its index is L > 0, but the extent of its markup depends on the elasticity (the price-sensitivity) of demand and strategic interaction with competing firms. The index rises to 1 if ...

  8. Price point - Wikipedia

    en.wikipedia.org/wiki/Price_point

    Technically, the price elasticity of demand is low (inelastic) at a price lower than the price point (steep section of the demand curve), and high (elastic) at a price higher than a price point (gently sloping part of the demand curve). Firms commonly set prices at existing price-points as a marketing strategy. [citation needed]

  9. Substitute good - Wikipedia

    en.wikipedia.org/wiki/Substitute_good

    The cross-price elasticity of demand shows the relationship between two goods, it captures the responsiveness of the quantity demanded of one good to a change in price of another good. [5] Cross-Price Elasticity of Demand (E x,y) is calculated with the following formula:
