I mentioned it in my comment elsewhere, but—from a quick look at the paper and the supplementary material—I don’t think it’s much like any of these. They don’t make any special mention that I could find of trying to translate purely economic measures into welfare. The only mention I could find about income adjustment is “rich/poor specifications” which appears to be about splitting the formula for growth of damages into one of two forms depending on whether the country is rich or poor.
Edit: They do mention “elasticity of marginal utility” in the discounting module section which is also known as “intergenerational inequality aversion”.
