life cycles of modern artists : theory, measurement, and implications

There have been two very different life cycles for important modern artists: some have made their greatest contributions early in their careers, whereas others have produced their best work late in their lives. Art's young geniuses have worked deductively to make conceptual innovations, while its old masters have worked inductively, to innovate experimentally. These two life cycles emerge from quantitative analysis of a wide range of research (a.o. transactions from fine art auctions). Author states that the two life cycles are not limited to painting, but also cleary appear in studies of the careers of important economists and poets.
