Here the guest editors of this special issue interview McAndrew on the structures of the art market, its sectorial and regional arrangements, and transformations in its historical, technical, and monetary operation. Their discussion highlights the rapid increase in prices for art and the global extension of the art market since the early-to-mid 2000s, as well as further changes to its operation wrought by the rise of online trading in the early 2010s.
