This is probably a naive question for economists, but I am a lawyer with limited understanging of econ and thus I am not confident about how to answer this question. Assume we have an agricultural production function with contstant return to scale. One factor contributing to production is water. Now climate change hits and hits the elasticity of water (but does not impact elasticity of other factors) then I would say, depending on which direction the elasticity of water heads, the return to scale will change to increasing or decresing. Does this make sense given the assumptions?
