What kind of changes in underlying conditions can cause the supply curve to shift?

The supply curve can shift due to changes in production costs, such as variations in the prices of raw materials, labor, or energy. Technological advancements that enhance production efficiency can also lead to an outward shift in the supply curve. Additionally, changes in government policies, such as taxes, subsidies, or regulations, can impact supply by altering the cost structures for producers. Lastly, external factors like natural disasters or geopolitical events can disrupt supply chains and shift the curve.
