So... how DO we get more of public good things?
Serious question for Tim.
Let us suppose for a moment we consider more science to be a public good, in the sense that the more science we do the greater the benefit is likely to be for all human-kind, competitors and collaborators alike, in the long run.
In that case, how does economics suggest we proceed in order to maximise the amount of science done by the human race in toto?
Has anyone tried it? If so, what were the results, compared with other alternative approaches?
