Characteristics of the law of demand : There is an inverse relationship between price and quantity demanded. Definition: The Law of Demand explains the downward slope of the demand curve, which posits that as the price falls the quantity demanded increases and as the price rise, the quantity demanded decreases, other things remaining unchanged. As prices fall, we see an expansion of demand. It is the main model of price determination used in economic theory. And this table that shows how the quantity demanded relates to price and vice versa, this is what we call a demand schedule. A rising price causes capital investment to increase supply. Plotting the above law of demand graphically. Law of demand. The law of demand states that the demand is inversely related to price other things remaining constant (ceteris paribus).

Law of demand is defined as “quantity demand of product decreases if the price of the product increases.” That is if the price of the product rises then the quantity demand falls.

When drawing a demand curve, economists assume all factors are held constant except one – the price of the product itself. Many factors affect the law of demand, apart from the price being the main reason there are many other factors affecting demand.Whenever there is a change in non-price factors, the entire curve shifts leftward or rightward whatever the case may be.

Hence, the demand for the bananas, in this case, was reduced by one dozen. In other words, the marginal utility curve of goods is downward sloping.

Alfred Marshall defines it as "Other things remaining the same, the amount demanded increases with a fall in price and diminishes with a rise in price."

The law of demand refers to the relationship between the quantity of the product demanded and the price of a product. FActors of demand. The demand curve is a negatively slopped curve moving from left to right, showing the inverse relationship. Therefore, the Law of Demand is an inverse relationship between price and quantity demanded. The law of demand thus states that, with all other elements remaining constant, the quantity of a product reduces as its price drops. Demand. What Does Law of Demand Mean?
