Kysyntäeroa

Kysyntäeroa refers to the difference between the quantity of a good or service that consumers are willing and able to purchase at a given price and the quantity that producers are willing and able to sell at that same price. In a perfectly competitive market, the equilibrium price is the point where the quantity demanded equals the quantity supplied, resulting in no kysyntäeroa.

However, various factors can lead to a kysyntäeroa. A shortage occurs when the quantity demanded exceeds the quantity supplied, typically at a price below the equilibrium. This can happen due to price controls, unexpected surges in demand, or disruptions in supply chains. In a shortage, consumers may face empty shelves, longer wait times, and potentially have to pay higher prices on the black market.

Conversely, a surplus arises when the quantity supplied exceeds the quantity demanded, usually at a price above the equilibrium. This can result from overproduction, a decrease in consumer demand, or a decline in the popularity of a product. In a surplus situation, producers may be left with unsold inventory, leading to potential price reductions or even the disposal of goods. Understanding kysyntäeroa is crucial for analyzing market dynamics, predicting price changes, and formulating economic policies.
