Here is an excerpt of Professor Don Boudreaux’s excellent piece on why central planning fails.
Attempts to centrally plan economies are very much like attempts to fly by dressing like and flapping like a bird: utterly futile because the most that can be observed of any successful economy are a handful of large details (“assembly lines,” “retail outlets”…..). The vast majority (99.99999999999…9 percent) of the details that must work reasonably well aren’t observed by the would-be central planner. What Hayek called “knowledge of the particular circumstances of time and place” – knowledge of details spread today across the globe and across billions of different human minds – is not incidental to the successful operation of a modern economy. Utilizing that knowledge – vast, deep, changing, incredibly fine-grained detailed knowledge – is the very key to a successful market economy.
Central planning is as futile as trying to strap on wings and fly like a bird – and potentially as calamitous.
Of course, few people today advocate full-scale central planning of economies. But smaller-scale interventions suffer the same problems as do attempts at central planning: inevitably inadequate knowledge of how to intervene. Asserting, for example, that the key to economic recovery is to “increase aggregate demand” is a fiction borne from observing a true, but only large and inadequate, fact about successful economies: most producers, at any given time, are able to sell most of what they plan to sell. But to leap from this observation to the conclusion that “therefore, government can stimulate economic recovery by increasing aggregate demand” is akin to a human being costumed-up as a bird and leaping off of a mountaintop, flapping away, hoping, hoping, hoping to fly.
The failure of central planning all boils down to one thing: the limits of knowledge.
