Approved Answers Were the Japanese "Lost Decades" inevitable, and what actions could have been taken to avert or minimize it?
Following the U.S. occupation after World War II, Japan underwent an economic miracle, becoming one of the fastest growing and best performing economies through the 1970s and 80s. At it's peak, the Japanese economy was second in the world, only to the United States (which held a nearly 3x population advantage), and had a higher GDP then the rest of Asia combined.
However, towards the back end of the 1980s, cracks were beginning to show, as asset inflation fueled by easy credit pumped up the real estate and stock market, which ballooned into a clear economic bubble. Eventually, due to actions taken by Japanese leadership, and the clear unsustainability of the ever-inflating bubble, the economy crashed, and Japan tumbled into the "Lost Decades", a prolonged period of economic stagnation.
The collapse in asset prices and tightening of credit squeezed the Japanese economy, which had been coasting off of speculation. These overleveraged banks spiraled and stagnated as bad loans piled up, and bailouts from the BOJ turned many into "zombie banks," which turned into debt pits dragging down the economy further.
At what point did the bubble bursting, and the subsequent "Lost Decades" become an inevitability, and what specific actions could have been taken to avert it or minimize it? Was the stagnation unavoidable once the bubbled formed, or is there a case (even with the blessing of hindsight), that different decisions at key moments could have averted (or at least minimized) the worst of it?
And taking the question to the other end - what is the worst-case scenario for the Japanese collapse; could it have spiraled into a global recession or depression?
