tarjontakäyrä

Tarjontakäyrä, also known as a supply curve, is a fundamental concept in economics that illustrates the relationship between the quantity of a good or service that a producer is willing and able to supply at various price levels, all else being equal. This curve is a graphical representation of the supply schedule, which is a table that lists the quantities supplied at different prices.

The supply curve is typically upward-sloping, reflecting the law of supply, which states that, other things being equal, an increase in the price of a good or service leads to an increase in the quantity supplied, and a decrease in the price leads to a decrease in the quantity supplied. This relationship is based on the assumption that higher prices encourage producers to supply more of a good or service, as they can achieve higher revenues.

Several factors can shift the supply curve, including changes in production costs, technological advancements, changes in the number of sellers, and changes in consumer preferences. For example, a decrease in production costs would shift the supply curve to the right, indicating that more of the good or service can be supplied at each price level.

The supply curve is a crucial component of market analysis, as it helps to determine the equilibrium price and quantity in a market. By examining the interaction between the supply curve and the demand curve, economists can analyze market dynamics and make informed predictions about market behavior.
