What primarily determines the extent of real GDP response to price level changes along the short-run aggregate supply curve?

The response of real GDP to changes in the price level along the short-run aggregate supply curve is influenced by multiple factors, making the comprehensive choice that includes all of them the most accurate. Each of these elements plays a crucial role in determining how much real GDP can change in response to shifts in the price level.

The speed at which input prices adjust and how quickly individuals gain information is significant because if input prices are slow to adjust, firms can benefit from higher prices in the short run, encouraging them to increase production. This aspect adds to the responsiveness of real GDP as firms react to price changes.

The ability of firms to hire additional inputs, especially workers, also impacts real GDP. If firms have the flexibility to quickly recruit and employ more labor in response to an uptick in demand indicated by higher price levels, they can significantly boost their output.

Furthermore, the ability to use existing workers and capital more intensively is vital. In the short run, firms may not always be able to hire more workers due to constraints, but they can increase capacity utilization by having current workers work longer hours or by using machines more effectively. This increased intensity of production allows firms to respond to price changes without needing to change the number of inputs.

The cumulative effect of
