Point elasticitySee elasticitySimilar MatchesElasticityElasticityA measure of responsiveness of one economic variable to another -- usually the responsiveness of quantity to price along a supply or demand curve -- comparing percentage changes (%D) or changes in logarithms (d ln). The arc elasticity of x with respect to y is e = %Dx/%Dy. The point elasticity is e = d lnx/d lny = (y/x)(dx/dy). Supply elasticitySupply elasticityThe elasticity of a supply function, usually with respect to price. Elasticity of substitutionElasticity of substitutionThe elasticity of the ratio of two inputs to a production (or utility) function with respect to the ratio of their marginal products (or utilities). With competitive demands, this is also the elasticity with respect to their price ratio. For example, with factors L,K and factor prices w,r, the elasticity of substitution of a production function F(K,L) is s = (wL/rK)d(K/L)/d(w/r). Armington elasticityArmington elasticityThe elasticity of substitution between products of different countries. Elasticity of demand for importsElasticity of demand for importsThis is normally the price elasticity of demand for imports of a country, either for a single industry or for the aggregate of all imports. The latter plays a critical role in determining how the country's balance of trade responds to the exchange rate. See Marshall-Lerner condition.
