Where next for discrete choice health valuation – part three

Where next for discrete choice health valuation – part three This is the last part of a series of three pieces on the valuation of health/well-being using discrete choice tasks. It should be borne in mind that this covers several stated preference (SP) methods, including discrete choice experiments (DCEs), best-worst scaling (BWS) and ranking studies. […]

Where next for discrete choice health valuation – part two

Where next for discrete choice health valuation – part two Part one of this series on the valuation of health (or quality of life) using discrete choice experiments (DCEs) and their variants concentrated on the tension between the size of the descriptive system and the needs of valuation. In particular, it summarised some disappointing findings […]

Where next for discrete choice health valuation – part one

Where next for discrete choice health valuation – part one My final academic obligations concerned two projects involving valuation of quality of life/heath states. Interestingly, they involved people at opposite ends of the age spectrum – children and people at the end of life. (Incidentally I am glad that the projects happened to be ending […]

yes its rovio who hit us after THEIR mistake

So, I made a post about an unnamed company that screwed up in its game design. I spared its blushes by not naming it…..I thought that it would give it a chance to learn from its mistake and move forward WITHOUT retrospectively penalising game players. I was wrong. It found a way to reduce the […]

highly efficient designs are not the bees knees

Statistical efficiency v cognitive efficiency  I was reminded yesterday of a study I am part of. In fact, I am/was effectively chief investigator (A) on it, since I was given full control over the design of “that half” of the study sample. Thus, for the purposes of this post, I refer to that half over […]

what’s the decision rule?

Another decision we had to think about over the past couple of days was “what is the threshold when using the capabilities approach?” A lot of people got hung up on finding a “threshold” like the cost –per-QALY one. Frankly I think that is not the way to go when considering well-being. We just look […]

end of life conceptual stuff

The last couple of days (8th and 9th September 2015)  I was in Birmingham for the final “Econ EndofLife” European funded project meeting and the advisory (steering) group meeting. Interesting discussion and it is useful to set out my contributions to the debates that were held, so they are on public record. One discussion we […]

Health care choices when people are ageing

Earlier this year I gave some advice to Michael Nicholls, a lawyer, following a request from a mutual friend. Michael had to talk about the challenges of health care funding in the presence of an ageing population. My/our friend knew I had a different take on this – my sympathy with the arguments made by […]

Are your customers smarter than you?

I recently became bored with the one game (app) that I downloaded to my tablet. I thought the game developers were getting greedy. I recognise the “wait, or use an in-app purchase to unlock stuff” model for free apps – it’s fine. However, when the ratio of game-playing time to wait-time becomes too low one […]
