This paper evaluates the presence of heterogeneity, by household type, in the elasticity of substitution between food … establish the presence of heterogeneity in the elasticity of substitution and in the intensity parameter. We find that the … elasticity of substitution is low for all household types. …

widely used assumption that technology in the final sector displays constant elasticity of substitution (CES) across the …

This paper uses normalized constant elasticity of substitution production functions to estimate the elasticity of … substitution and labour-augmenting technical change in South Africa over the period 1994-2012. We find elasticities of 0.6-0.9 and …

We provide a general theoretical characterization of how technology choice affects the long-run elasticity of … substitution between capital and labour. While the shape of the technology frontier determines the long-run growth path and the …

system integration constraints in a model, WITCH, characterized by a Constant Elasticity of Substitution (CES) framework. …

We later solve the model for values of the elasticity of substitution that differ from one. This second … experiment shows that while a higher elasticity of substitution helps to increase the aggregate stock market volatility and hence …

We generalize the normalized Constant Elasticity of Substitution (CES) production function by allowing the elasticity …) capital–labor ratios, or (iv) capital–output ratios. Ensuing four variants of Isoelastic Elasticity of Substitution (IEES … of substitution to vary isoelastically with (i) relative factor shares, (ii) marginal rates of substitution, (iii …
