Over the last three years, the complex system of the global economy flipped from boom to bust -- all because a bunch of Americans started to default on their subprime mortgages, thereby blowing huge holes in the business models of thousands of highly leveraged financial institutions. The next phase of the current crisis may begin when the public begins to reassess the credibility of the radical monetary and fiscal steps that were taken in response.
Neither interest rates at zero nor fiscal stimulus can achieve a sustainable recovery if people in the United States and abroad collectively decide, overnight, that such measures will ultimately lead to much higher inflation rates or outright default. Bond yields can shoot up if expectations change about future government solvency, intensifying an already bad fiscal crisis by driving up the cost of interest payments on new debt. Just ask Greece.
Ask Russia too. Fighting a losing battle in the mountains of the Hindu Kush has long been a harbinger of imperial fall. What happened 20 years ago is a reminder that empires do not in fact appear, rise, reign, decline and fall according to some recurrent and predictable life cycle. It is historians who retrospectively portray the process of imperial dissolution as slow-acting. Rather, empires behave like all complex adaptive systems. They function in apparent equilibrium for some unknowable period. And then, quite abruptly, they collapse.
Washington, you have been warned.

Rise and fall
Niall Ferguson's op-ed in today's LA Times is a fine conversation starter. Seeking patterns in the rise and fall of nations is an old sport and not ever likely to go away. Predictions of a U.S. eclipsed by fill-in-the-blank (the USSR, the EU, Japan, Islam, China, etc.) have (mostly) come and gone. Along the way, there are inevitably some silly things that are asserted, but this is in my view interesting, not as forecast, but as discussion.
