Quote of the Day: The Virtue of Market Inefficiency

an inefficiency exists when, for a given person at a given time and place, the cost of an action outweighs the benefit.  We’ve seen that to rationally calculate costs and benefits you need money prices of inputs and outputs, of steel and bridges.  So when government erodes private property rights, interferes with trade, distorts prices, and manipulates money, it doesn’t just make it harder to be efficient; it also pulls the rug from under the very ability to spot inefficiencies at all.

Using the rules of arithmetic, for example, it’s easy to see that the statement 1 + 2 = 4 is wrong, but what about  _ + _ = _ ?  What’s the solution to this “problem”?  Is there even a problem here?  Money prices fill in the blanks; they “create errors”—i.e., reveal mistakes that no one could see without them—that alert entrepreneurs might then perceive and correct. If mistakes and inefficiencies remain invisible, the search for better ways of doing things could never get off the ground.

An economy without inefficiencies is either one where knowledge is so perfect that no one ever makes a mistake, or it’s one in which government policy has effectively foreclosed the very possibility of inefficiency.  In a world of surprise and discovery, of experiment and innovation, the former is impossible; the latter sort of economy, as Mises showed almost 100 years ago, is impossible as well as intolerable.

So a living economy needs to “create” inefficiencies, and lots of them, to set the stage for greater efficiency and ongoing innovation.
