Intermediary liability and trade in follow-on innovation.

Intellectual property rights have changed the market value and direction of artistic innovation throughout art history, in particular when new creations built on the art of predecessors. In this paper, we test how changes in legal frameworks and litigation risks affected market value and commercial trade around artistic reuses in the figurative arts and the 'Appropriation Art' movement in particular. Appropriation artists borrow images from different sources and incorporate them into new, derivative works of art.
