perils of efficient design paper accepted

Well, this it turning out to be a good week. First I hear the BWS book was published on time.

Now a paper that two of the global experts on discrete choice experiments found ground-breaking has been accepted for publication! The paper had previously been rejected by a another good journal – a decision I (and, crucially, others) found unfair since the two referee reports did not appear to be recommending rejection (though one was fairly critical and the other didn’t really “get” a lot of what we did, it being work that challenged some tenets of the current economic orthodoxy).

Anyway the paper is called “Are Efficient Designs Used In Discrete Choice Experiments Too Difficult For Some Respondents? A Case Study Eliciting Preferences for End-Of-Life Care” by T.N. Flynn, Marcel Bilger, Chetna Malhotra and Eric Finkelstein and has been accepted by Pharmacoeconomics.

The background to the paper and its implications will form the second blog in the series I am writing about the future of health state valuation using DCEs. Suffice to say, it is revolutionary because we got respondents to answer TWO DCEs, which differed radically in their statistical efficiency – one was 100% efficient, the other 40-50% efficient. The theoretical advantages of the former were, however, heavily attenuated by the fact many respondents resorted to heuristics that didn’t represent their true decision rule – causing biased estimates. Twas a cool paper, even if I say so myself. Anyway I shall follow up on this later in the week, that’s enough for today.
