Ian Bateman

Environmental economist who showed the decoy effect operating on the valuation of non-market goods.
Who they are
Bateman works on choice experiments and contingent valuation, where attributes are genuinely numerical and the stakes are public policy rather than retail.
Key papers
Bateman, I. J., Munro, A., & Poe, G. L. (2008). Decoy effects in choice experiments and contingent valuation: asymmetric dominance. Land Economics, 84(1), 115-127.
Key ideas
Introducing an asymmetrically dominated option significantly affected choices between the non-dominated options in the same choice set.
That effect then translated into significant impacts on subsequent valuations of those options.
This is the effect working where attributes really are numbers, which is the territory the sceptics say it belongs in.
