3.5 : Impact of Input Prices on Supply Curve

Input prices encompass the costs of all factors involved in the production process, including raw materials, labor, machinery, and technology. These prices directly influence a producer's operational expenses.

When the cost of inputs rises, production becomes more expensive for producers. In response, producers may reduce their output to maintain profitability, resulting in a decrease in supply.

On the other hand, lower input prices lead to reduced production costs and increased profits for businesses. As a result, producers increase their output, leading to an increase in supply.

Consider a smartphone manufacturer. If labor costs rise while all other factors remain constant, the cost of production of smartphones will also rise. The manufacturer may produce fewer smartphones, causing a leftward shift in the supply curve.

In contrast, if labor costs decrease, the production cost of smartphones will fall. This could prompt the manufacturer to increase production, leading to a rightward shift in the supply curve.

To conclude, input prices help predict how changes in production costs can influence the supply curve.
