Prices of complementary goods
Hi all. I think there is a factual inaccuracy in this article. Towards the bottom of the first paragraph the article says: "The prices of complementary goods are related in the same way: if the price of one good rises, so will the price of the other, and vice versa."

I could be wrong, but I don't think this is true. If anything, the prices of complementary goods move in opposite directions. Take, for example, peanut butter and jelly. Say the price of peanut butter falls because of fall in the price of input resources. This will increase the demand for jelly resulting in higher jelly prices. If this example is legit, we see prices of complementary goods moving in OPPOSITE directions, not the same direction.

Happy to be corrected if I am wrong. If I am wrong, I would love for someone to tell me where my thinking goes astray.47.146.172.221 (talk) 04:24, 12 February 2018 (UTC)
