Demand Explained: The Law of Demand Principles

The law of demand is a fundamental concept in microeconomics that describes the relationship between the price of a good or service and the quantity consumers are willing and able to purchase.

Key Principle of Demand

• The law states that, all else being equal (ceteris paribus), as the price of a good or service increases, the quantity demanded will decrease, and conversely, as the price decreases, the quantity demanded will increase.
• This represents an inverse relationship between price and quantity demanded.

Analyzing the Options

• Option 1 & 2: These options describe a direct relationship where demand moves in the same direction as price. This is incorrect according to the law of demand.
• Option 4: This option suggests price has no influence on demand, which is contrary to basic economic principles.
• Option 3: This option accurately captures the inverse relationship (price increase leads to demand decrease) and includes the crucial condition of ceteris paribus (all other factors held constant).

Therefore, the statement accurately describing the law of demand is that as price increases, demand decreases, ceteris paribus.
