# What is the economic meaning of distribution parameter in a CES-production function?

This is the production function (two input factors: $$x_1$$ and $$x_2$$)

$$q=A[δx_1^ρ+(1-δ)x_2^ρ]^{\frac{1}{ρ}}$$

If distribution factor $$δ$$ is set to increase, what are the economic impacts on these two input factors? Substitution elasticity remains unchanged.

In this answer you can see that $$\delta$$ becomes the exponent in the Cobb-Douglas function as $$\rho \to 0$$, i.e. as the elasticity of substitution becomes unity.
