Simple Supply and Demand

Knight often despaired at the general public’s inability to understand even simple economic truths. In his 1950 presidential address to the American Economic Association, Knight said:

Of late I have a new and depressing example of popular economic thinking, in the policy of arbitrary price-fixing. Can there be any use in explaining, if it is needful to explain, that fixing a price below the free-market level will create a shortage and one above it a surplus? But the public oh’s and ah’s and yips and yaps at the shortage of residential housing and surpluses of eggs and potatoes as if these things presented problems any more than getting one’s footgear soiled by deliberately walking in the mud.
