This month we’re covering black markets: those underground exchanges of contraband that power parallel economies throughout the world. Goods both human and inanimate are traded in these shadowy venues, where everything from kidneys to diamonds is available, often at horrific cost.  In fiction and essays, Wang Bang, Abdelilah Hamdouchi, Vladimir Lorchenkov, Jason Miklian, Dominique Manotti, Dmitri Novosolov, Edgard Telles Ribeiro, and Ye Yonglie explore clandestine systems around the world.
