A factory provides a much needed product to the market, but it also provides ugly pollution and waste. The 11th episode of a 21-part Economic Lowdown podcast series investigates the concept of positive and negative externalities. Historians analyze the cost, both good and bad, of purchases and products. A short podcast explains how externalities are made and what people should do to curb the negative and support the positive.
