# What is the empirical price elasticity of demand for insulin?

A lot of textbooks say that demand for insulin is perfectly inelastic. I don’t think this is quite true (and I am a type 1 diabetic). It’s clearly very inelastic, but not perfectly so. There are things you can do to reduce your insulin intake, e.g. eat less carbohydrates.

I’m curious if any studies have actually gone out and measured this…
