I have really enjoyed my readings in economics over the last few years. I think the discipline offers tremendous tools for understanding our world. It helps us create narratives which make sense. Unfortunately that last bit, the reassuring narrative, is also its great danger. As Taleb and others have pointed out, narrative understanding can easily become narrative fallacy. We can build a narrative but we can’t really know if it is true.
If we invest in the wrong narrative … [bad things happen]
The recent economic unpleasantness has highlighted that sort of risk in economics, and increasingly it is appearing as an economics backlash:
THE DEEPENING ECONOMIC downturn has been hard on a lot of people, but it has been hard in a particular way for economists. For most of us, pain and apprehension have been mixed with a sense of grim amazement at the complexity of what has unfolded: the dense, invisible lattice connecting house prices to insurance companies to job losses to car sales, the inscrutability of the financial instruments that helped to spread the poison, the sense that the ratings agencies and regulatory bodies were overmatched by events, the wild gyrations of the stock market in the past few months. It’s hard enough to understand what’s happening, and it seems absurd to think we could have seen it coming beforehand. The vast majority of us, after all, are not experts.
But academic economists are. And with very few exceptions, they did not predict the crisis, either. Some warned of a housing bubble, but almost none foresaw the resulting cataclysm. An entire field of experts dedicated to studying the behavior of markets failed to anticipate what may prove to be the biggest economic collapse of our lifetime. And, now that we’re in the middle of it, many frankly admit that they’re not sure how to prevent things from getting worse.
The best economists have always been humble about their tools and the limits to their vision. A few have been grandiose (or worse, condescending) in their dealings with the public. It’s hard not to think the latter are due for a take-down … but I suppose to rise to the occasion we should applaud the first group and admit our own uncertainty about the world.
It’s another case when the simple truth is that no one knows the future.
