Meanwhile, law of supply is the law of supply states that quantity supplied rises when price rises, holding all else constant. Here is how they compare side by side.
The law of demand states that quantity demanded falls when price rises, holding all else constant.
The law of demand describes the inverse relationship between price and quantity demanded. When the price of a good rises, consumers are willing and able to buy less of it. Conversely, when the price falls, consumers are willing and able to buy more. This holds true as long as other factors like income and preferences remain constant.
The law of supply states that quantity supplied rises when price rises, holding all else constant.
The law of supply describes the positive relationship between price and quantity supplied. When the price of a good rises, producers are willing and able to supply more of it. Conversely, when the price falls, producers are willing and able to supply less. This holds true as long as other factors like technology and input costs remain constant.
