Tarjontakäyrän

Tarjontakäyrä, or supply curve, is a fundamental concept in economics that illustrates the relationship between the price of a good or service and the quantity that producers are willing and able to offer for sale at that price. Typically, the supply curve slopes upwards, indicating a positive correlation between price and quantity supplied. This means that as the price of a good increases, producers are generally incentivized to supply more of it, and conversely, as the price falls, they tend to supply less.

Several factors can cause a shift in the supply curve, meaning a change in the quantity supplied at every price level. These factors include changes in the cost of production, such as wages, raw material prices, or energy costs. Technological advancements can also affect supply, often leading to increased efficiency and a downward shift in the supply curve (meaning more can be supplied at a lower cost). Government policies, like taxes or subsidies, can also influence supply. For example, a subsidy might encourage producers to supply more, shifting the curve to the right.

The equilibrium price and quantity in a market are determined by the intersection of the supply curve and the demand curve. Where the two curves meet, the quantity demanded by consumers exactly matches the quantity supplied by producers, resulting in a stable market price. Understanding the supply curve is crucial for analyzing market dynamics, predicting price changes, and evaluating the impact of various economic policies.
