When I was writing my previous blog post, I used shoes and shoelaces as an example of complements (in economic theory, when the price of one good goes up, demand for its complement will go down).
As I continued writing, I realized that shoes and shoelaces was a lame example and that perhaps cars and gasoline would be a better example. Unless you've got an electric car or you just want somewhere to sit, a car isn't much use without gasoline. Likewise, unless you're an arsonist, you can't do much with a jug of gasoline if you don't have a car.
Thank you, British Academy
