Final answer:
Economists from both Keynesian and neoclassical schools criticized the stimulus package for different reasons.
Step-by-step explanation:
Economists from both Keynesian and neoclassical schools criticized the American Recovery and Reinvestment Act, also known as the stimulus package, for various reasons.
A Keynesian economist might be critical of the stimulus package because they believed that it did not go far enough in stimulating the economy. They would argue that the package should have been larger and included more government spending to create jobs and boost demand. They might also criticize the package for not focusing enough on helping the most vulnerable populations.
On the other hand, neoclassical economists might be critical of the stimulus package because they believed that it relied too heavily on government intervention and spending. They would argue that the package could create long-term negative effects, such as inflation, and that market forces should be allowed to naturally guide the economy out of recession.
