Law of Demand
What is Law of Demand?
The Law of Demand states that, as the price of a good or service increases, its demand decreases. This law is based on consumer behavior whereby people prefer to purchase more of a good when its price is lower and less when its price is higher. In other words, the Law of Demand states that there is an inverse relationship between price and the quantity demanded.
Assumptions of law of demand
The law of demand states that, all other things being equal, the quantity demanded of a good and services is inversely related to its price. This is one of the most foundational principles in economics, based on a few key assumptions:
1. Consumer Preference for Lower Prices: Consumers generally prefer to buy more of a product when its price is lower, opting for cheaper alternatives when available.
2. Stable Consumer Preferences: It assumes that people's tastes and incomes remain constant over time. This means changes in demand are mainly driven by price, not by shifts in what people like or how much money they have.
3. Availability of Substitutes: The law assumes that there are good substitutes for most products. If a product has few or no substitutes, people might still buy it even if the price rises.
4. Perfect Information: Consumers are assumed to have complete knowledge about available products and their prices, allowing them to make informed choices.
Exception of law of demand
The law of demand states that, all else being equal, when the price of a good or service decreases, the quantity demanded increases, and vice versa. There are some exceptions:
1. Giffen Goods: These are type of inferior goods where demand increases as the price rises. This happens because the income effect is stronger than the substitution effect. Example, if the price of bread goes up, low-income consumers might end up buying more bread instead of switching to pricier alternatives.
2. Veblen Goods: These are luxury items whose higher prices make them more desirable due to their status symbol. As the price of a Veblen good increases, demand can also increase because people want to showcase their wealth.
3. Essential Goods: Some necessities, like certain medications or basic food items, may see steady demand regardless of price changes, as consumers need them regardless of cost.
4. Speculative Demand: In some cases, demand may rise if consumers expect prices to increase in the future. Example, if people anticipate a rise in the price of a stock, they might buy more now, even if the price is high.
5. Quality Perception: If consumers perceive that a higher price correlates with better quality, they might demand more of a product as its price increases.
Implications of Law of Demand
The Law of Demand has various implications for businesses, producers and consumers alike.
For Businesses: Companies need to be mindful of how changes in prices might influence consumer behavior and their ability to sell products.
For Consumers: Understanding this law allows them to make smart purchasing decisions by taking into account both quality and prices when making decisions about what goods or services they should buy.
For Producers: Producers can use this law to maximize their profits by setting prices at an optimum level which balances satisfying customer demand while still providing sufficient profits.
