 | | The Cobb-Douglas is quite restrictive; it forces the elasticity of substitution between all pairs of inputs to equal 1, eliminating, for example, the possibility of complementary inputs. |
 | | The CES model is a compromise between these two extremes, because it allows the elasticity of substitution between inputs to be any (constant) number. |
 | | Notice that the three inputs are forced to have the same exponent, -beta, and that the three inputs have coefficients that must sum to 1 (delta1, delta2, and 1-delta1-delta2). |
