Numerous empirical studies successfully measure both the consumption and production elasticities of substitution across various sectors and economic contexts.
The claim asserts that empirical measurements exist for both consumption and production elasticity of substitution. Multiple papers in the provided set explicitly calculate or estimate these values for consumption (e.g., intertemporal substitution of consumption) and production (CES and Cobb-Douglas production functions at sectoral and national levels). Therefore, the claim is fully supported by the evidence.
