It is standard practice to treat input-output (I-O) technical coefficients as fixed. The coefficients are fixed when $\sigma $σ, the elasticity of substitution, is zero, a restriction mostly not supported by 25 years of I-O tables for Australia. We offer a simple way of allowing for variable coefficients with a CES approach. Finally, using various values of $\sigma $σ in CGE simulations establishes that taking coefficients as fixed has misleading economic implications.
