  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. Law of demand - Wikipedia

    en.wikipedia.org/wiki/Law_of_demand

    The variation in demand with regards to a change in price is known as the price elasticity of demand. The formula to solve for the coefficient of price elasticity of demand is the percentage change in quantity demanded divided by the percentage change in Price. = / /

  4. 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 ...

  5. 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 ...

  6. Hicksian demand function - Wikipedia

    en.wikipedia.org/wiki/Hicksian_demand_function

    Marshallian demand curves show the effect of price changes on quantity demanded. As the price of a good rises, ordinarily, the quantity of that good demanded will fall, but not in every case. The price rise has both a substitution effect and an income effect. The substitution effect is the change in quantity demanded due to a price change that ...

  7. Slutsky equation - Wikipedia

    en.wikipedia.org/wiki/Slutsky_equation

    where ε p is the (uncompensated) price elasticity, ε p h is the compensated price elasticity, ε w,i the income elasticity of good i, and b j the budget share of good j. Overall, in simple words, the Slutsky equation states the total change in demand consists of an income effect and a substitution effect and both effects collectively must ...

  8. 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%.

  9. Cross elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Cross_elasticity_of_demand

    Change in demand due to price change of rival products; The production function of the cellophane; The slope and position of the cost curves of rival products. In other words, the competitive relationship between two goods (cross-price elasticity) can not be simply concluded by price change, as price change arises from both cost and demand factors
