Definition
Consumer surplus is an economic measure of consumer benefits resulting from market competition. It refers to the surplus value created when consumers pay a price lower than what they are willing to pay for a product or service. In simple terms, consumer surplus measures the additional benefit consumers receive by paying less than their maximum willingness to pay.
Origin
The concept of consumer surplus was first introduced by French economist Jules Dupuit in 1844 and later developed and popularized by Alfred Marshall in the late 19th century. Marshall elaborated on this concept in his book 'Principles of Economics,' establishing it as a key tool for assessing market efficiency.
Categories and Features
Consumer surplus can be categorized based on market types and product characteristics. In perfectly competitive markets, consumer surplus is typically larger due to lower market prices. In monopolistic markets, consumer surplus may be smaller as monopolists can raise prices. Features of consumer surplus include its dependence on the difference between consumer willingness to pay and market price, and its role as an indicator of consumer welfare.
Case Studies
A typical case is when Apple launches a new iPhone, and many consumers are willing to pay more than the market price, but they actually pay less than their willingness to pay, resulting in consumer surplus. Another example is Amazon's promotional events, where consumers purchase goods at discounted prices, paying less than their willingness to pay, thus increasing consumer surplus.
Common Issues
Common issues investors face when applying the concept of consumer surplus include accurately estimating consumer willingness to pay and evaluating consumer surplus under different market conditions. A common misconception is that consumer surplus can always be calculated through simple price differences, overlooking the complexity of consumer preferences and market dynamics.
