The document discusses the law of supply and how it relates to productivity. It explains that according to the law of supply, the higher the price of a good or service, the more suppliers will offer it for sale. The lower the price, the less suppliers will offer. Supply is based on the profit motive - suppliers want to make money. The supply curve slopes upward, showing the relationship between price and quantity supplied. Changes in factors of production like resources and labor can affect supply in both the short and long run.
