The analysis

The claim states that an increase in the supply of a substitute good alters the price difference between substitutes. This is a basic deductive implication of supply and demand curves intersecting: adding supply to one good shifts its price, which directly alters the price differential between it and its substitutes. Because this follows logically by definition and everyday observation of market mechanics, it is categorized as common knowledge (Step 0).
