Are Markets Better Described as Robust than Efficient?
Something that I think all of us with private sector jobs experience in our day to day lives is just how incompetent a large number of private businesses are. These may be our customers, suppliers, or another division. Yet, somehow, these businesses thrive despite not really having a good grasp of basic administrative procedures, financing, or sometimes even customer service.
Despite this, we often write and speak of private sector actors as if they are brilliant and efficient individually, despite the experiences of our everyday lives.* We simply assume as a result of mere market success that a business or individual has ability and competence. This isn’t surprising, the just world hypothesis is a powerful cognitive bias which leads us to believe that the system as a whole must be more just than what our individual experiences would lead us to conclude. However, there is no property of the market system which should lead to this belief.
What’s more notable is how little this impacts how we think about the market system as a whole. After all, given an immortal, perfectly rational, and omniscient central planner even the worst designed communist system would work beautifully. What’s remarkable about the market system is that it should lead to ever increasing levels of productivity and efficiency even if the individual actors are all completely incompetent. Competition and creative destruction should lead businesses to be ever better even if they only differ due to random variation alone.
