A hypothesis in an economic model is

Usually about a causal relationship, A statement that may be either correct or incorrect about an economic variable, Tested before it can be accepted (or not rejected).

According to the law of demand ​, there is an inverse relationship between price and quantity demanded. That​ is, the demand curve for goods and services slopes downward.​ Why?
