I know that the linearization of a CES (constant elasticity of substitution) funtion is a bit complicated. There is even an R package dedicated just for that - the econometric estimation and calculation of a CES function (of wich Cobb-Douglas, Leontief and linear production functions are special cases) - micEconCES. However, I can't find anything about the econometric estimation of a VES (variable elasticity of substitution) production function.

Is it (linearisation and/or econometric estimation) possible at all, or do the characteristics of the function not permit linearisation?

P.S. I'm aware that there are different forms of the VES function.

    $\begingroup$ It would be good if you included in your post a specific exaple of a VES function. $\endgroup$ – Alecos Papadopoulos Feb 12 '18 at 14:54
