Perhaps no economist was more vindicated by the global financial crisis than Hyman P. Minsky (1919-96). Although a handful of economists raised warnings as early as 2000, Minsky's warnings began a half-century earlier, with writings that set out a compelling theory of financial instability. Yet even today he remains largely outside mainstream economics; few people have a good grasp of his writings, and fewer still understand their full importance. Why Minsky Matters makes the maverick economist's critically valuable insights accessible to general readers for the first time. L. Randall Wray shows that by understanding Minsky we will not only see the next crisis coming but we might be able to act quickly enough to prevent it.
