The elasticity of substitution between capital and labor and, in turn, the direction of technical change are critical parameters in many fields of economics. Until recently, though, the application of production functions with non-unitary substitution elasticities (i.e., non Cobb Douglas) was...

Capital-labor substitution and TFP estimates are essential features of many economic models. Such models typically embody a balanced growth path. This often leads researchers to estimate models imposing stringent prior choices on technical change. We demonstrate that estimation of the...

In this paper, we seek to re-establish the link between the constant elasticity of substitution (CES) production function and neoclassical Solow growth theory. We do so in three dimensions. First, we review the increasing importance of the CES technology in modern dynamic macroeconomics, in...
