I, Pencil and the Free Market


Dr. Wolfram talks about the extraordinary power of the free market to answer what is known as “the information problem,” or in other words, how to supply precise amounts of goods to different places all over the world, without oversight.

The following video is a clip from Hillsdale’s Online Course: “Economics 101: The Principles of Free Market Economics,” featuring Gary Wolfram, the William E. Simon Professor of Economics and Public Policy.

Leonard Read, in 1950, wrote an article called, "I, Pencil," which became rather famous. In it, he points out all the coordination that's required for a pencil to be made, and how markets solve the problems of getting lumber from the Pacific Northwest, and rubber from Malaysia, and all the parts of a pencil assembled.

Milton Friedman also spoke of this in his book and his television series, "Free to Choose." It's interesting to know that Adam Smith wrote much the same thing about a woolen coat in Wealth of Nations in 1776.

Read and Smith point out that a market is able to bring together producers of all sorts of parts and allow those parts to be assembled into a product that, in the case of a pencil, is so inexpensive, we don't even know how much a pencil costs. If you open up your drawer, there are pencils. They're sort of like manna from heaven; they just show up. You can't even remember that you bought them. That's how inexpensive they are. It is truly amazing.

I want to go beyond this, to not only notice all the coordination that happened, but how markets work to solve what is called the information problem.

Suppose that I, as the president, said, "I want the czar of pencils to make sure that everyone has enough pencils, because it's so vital to our educational system." Think about it. If you were to be appointed the czar, how would you ensure that every retail establishment in America, at every moment in time, had exactly the right amount of pencils? Anyone could walk into a Costco in Menominee, Michigan, or a K-Mart in Mobile, Alabama, or a Walmart in Phoenix, Arizona, and there'd be pencils. And there won't be boxes and boxes and shelves and shelves of pencils, but exactly the right amount of pencils. Enough that you can figure out, "Yeah, I'll choose this one over that one," but not so many they're just excess wasted supply.

Could you realistically do that for the millions of retail establishments in America? Not just today, but August 15, and October 10, and December 23, every single day of the year. Your intuition is, "No, I probably couldn't do that," and you'd be correct. What's interesting to notice is that the market does, in fact, do that. Every day we'll wake up, and there'll be exactly the right amount of pencils. And exactly the right amount of Starbucks coffee, and exactly the right amount of peanuts ... Exactly the right amount of everything. You'll be able to find a vast array of goods in a town as small as Hillsdale and a city as large as New York City.

Why is it that markets provide the exact right amount of everything at every moment in time when a central planner can't? If you'd like to know, tune in to Lecture 6 of Economics 101.
