Zeckhauser examined the shift from single-author works to mostly multiple-author works, a shift in modern trends. He zeroed in on the target population comprising Nobel laureates and the younger population of winners of the John Bates Clark Award. Collaboration was absent among the first ten Nobel Prize winners on their single most cited work. Similar findings were found for the John Bates Clark Award. Besides the increasing needs for specialization, collaboration is lauded for its superadditiveness, where the contribution of two specialists amounts to a value greater than the sum of values of their individual contribution.
