I find it interesting that they awarded the prize to Shapley after Gale's death[0]. I always thought that there was some rule that prevented them from awarding the Physics Nobel Prize to Aharonov after Bohm died[1].
In this case, it is simply the post title being misleading, as it's not the Nobel prize these folks won, but the Nobel memorial prize in economics, which is a relatively new prize which is not part of the 5 Nobel prizes which had been given by Nobel's estate for more than a century.
Edit: oh I see they didn't reward a dead in this case, misread your comment..
