The Supply Curve Shifts is an economic concept that explains how the quantity of a product or service supplied in a market changes in response to a shift in the price. In other words, when prices go up, suppliers tend to increase their quantity of supply and vice versa. This can be due to changes in production costs, ease of access to resources or even the availability of substitutes. It’s an important concept for understanding economics, as it helps businesses keep track of their own supply curves, ensuring they remain competitive by altering their products and services accordingly.
