The increase in oil prices would likely shift the Aggregate Supply (AS) curve to the left due to higher production costs, while the financial crisis would shift the Aggregate Demand (AD) curve to the left due to reduced spending. Both shifts can affect the economy in the short run, but if potential output remains unchanged, the long-run impact on unemployment might be negligible, aligning with the natural rate of unemployment theory.
