Treasure Island: The Beauty of Trade

Russ Roberts has a great parable about the beauty of trade:

We all have a good intuitive understanding of the power of trade. At the simplest level, if you have something I want and if I have something you want, and we trade we each other, we're both better off.

So if I can knit and you can't, and if you can grow corn and I can't, it obviously makes sense for me to swap one of my sweaters for some of your corn. You and I might argue about the "price"—how many ears of corn one of my gorgeous sweaters is worth—but once the deal is done, you're warmer and I'm on my way to being less hungry.

Trade seems simple.

Almost two hundred years ago, David Ricardo discovered something not so simple about trade that came to be called comparative advantage. Here is a story that will let us explore the mysteries of trade together.

Read the whole thing! It's a great illustration of how trading with others makes everyone better off. There is a strong moral element here that I think is missed by many.
