...…suppliers through outsourcing, L is the amount of labour employed in-house, and , σ and a ρ are parameters satisfying 0 a 1, and 10 ρ , respectively.1 In (1) a is the distribution parameter (see e.g. Arrow et al (1961)) between the production factors, while σ captures the elasticity…...

...One of the advantages of formulation (2) is that it gets away from these unnecessarily tight restrictions to "neutrality" of one kind or another, without going all the way back to (1)....

...Incorporation of this hypothesis into a production function like (1) or (2) has led to so-called vintage models of production....

...If (2) is Cobb-Douglas, however, then is constant and we have a technical progress function which is linear, or at least linear at each instant of time; and conversely....

...It has been often shown that Hicks-neutrality is equivalent to (2) and a(T)/b(T) = constant, while Harrod-neutrality is equivalent to (2) and a(T) = constant....

...Most researchers have worked with the standard (ACMS) form, due to Arrow et al. (1961): Y = A (bKρ + (1− b)Lρ) 1 ρ where Y , K and L are output, capital and labor respectively, and where the elasticity of substitution σ = 1/(1 − ρ)....

...Hence the capital-output ratio can be calculated independently of the production function parameters, and used in equations (2) and (3) together with the researcher’s best guess of the capital share that will obtain asymptotically....

...Arrow et al. (1961) pointed out that the elasticity of substitution may vary with the level of development, but there is no reason to expect productivity to respond in a straightforward way to such a change, or to expect that a rising elasticity of substitution can be the “engine of growth” implied…...
