How do resources becoming more expensive affect aggregate supply?

• A. They decrease production costs
• B. They have no effect on aggregate supply
• C. They increase production costs
• D. They consistently lower output

Answer: (C)

Resources becoming more expensive leads to an increase in production costs for businesses. When the costs associated with inputs such as labor, raw materials, and energy rise, producers may not be able to produce the same quantity of goods and services without raising their prices. This situation ultimately results in a leftward shift in the aggregate supply curve, reflecting a decrease in the overall supply at given price levels.

Understanding this dynamic is crucial in economic discussions, as it highlights how changes in resource prices can directly impact the cost structure of production, ultimately influencing the economy's output and price levels. Higher production costs can lead firms to reduce their production capacity or scale back on hiring, further constraining aggregate supply in the economy.
