Cobb-Douglas and CES production functionThis paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production ...
there are constant returns to a scale. In Cobb-Douglas production function, only two input factors, labor, and capital are taken into the consideration, and the elasticity of substitution is equal to one. It is also assumed that, if any, of the inputs, is zero, ...

The most common method for calculating total factor productivity is the Cobb-Douglas production function. This function divides a business’s total output by the weighted geometric average of capital and labor. Usually, the weighted averages used are 0.7 for labor and 0.3 for capital. You must c...
The Constant Elasticity of Substitution Production Function or CES implies, that any change in the input factors, results in the constant change in the output. In CES, the elasticity of substitution is constant and may not necessarily be equal to one or

… not everyone is convinced about how much we really know on even the simplest question — the constant-output own-price elasticity of demand for aggregate labor. … Because this parameter is fundamentally important for understanding the impacts of such diverse policies as payroll taxation, subsidie...
