  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)

    When the tangent of the straight line or curve is steeper, the price elasticity (demand or supply) is smaller; when the tangent of the straight line or curve is flatter, the price elasticity (demand or supply) is higher. [7] Elasticity is a unitless ratio, independent of the type of quantities being varied. An elastic variable (with an absolute ...

  4. Demand - Wikipedia

    en.wikipedia.org/wiki/Demand

    At one point on a linear demand curve, demand is unitary elastic: an elasticity of one. For higher prices, the elasticity is greater than 1 in magnitude: demand is said to be elastic because percentage quantity changes are bigger than price changes. For prices below the point of unit elasticity, the elasticity is less than 1 and demand is said ...

  5. Price elasticity of supply - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_supply

    The price elasticity of supply (PES or E s) is commonly known as “a measure used in economics to show the responsiveness, or elasticity, of the quantity supplied of a good or service to a change in its price.” Price elasticity of supply, in application, is the percentage change of the quantity supplied resulting from a 1% change in price.

  6. Cobweb model - Wikipedia

    en.wikipedia.org/wiki/Cobweb_model

    In words, the convergent case occurs when the demand curve is more elastic than the supply curve, at the equilibrium point. The divergent case occurs when the supply curve is more elastic than the demand curve, at the equilibrium point (see Kaldor, 1934, page 135, propositions (i) and (ii).)

  7. 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 ...

  8. 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 ...

  9. Law of demand - Wikipedia

    en.wikipedia.org/wiki/Law_of_demand

    Price elasticity of demand can be classified as elastic, inelastic, or unitary. An elastic demand occurs when the percentage change in the quantity demanded is greater than the percentage change in price, meaning that a small change in price results in a large change in quantity demanded.
