Final answer:
Legislators debating for months on spending programs for economic manipulation exemplify the complications of active fiscal policy and the associated legislative and implementation lags that can lead to ineffective or untimely economic measures.
Step-by-step explanation:
The scenario where legislators debate for six months on which spending programs to use in order to influence the business cycle is an illustration of the challenges associated with active fiscal policy. When applying fiscal policy measures, there are considerable delays including the legislative lag, which is the time it takes to pass a bill, and the implementation lag, which is how long it takes for funds to be disbursed and projects to start after a bill is passed. During these delays, a recession may end before measures take effect, potentially exacerbating rather than smoothing business cycles, a concern raised by some neoclassical economists about government policy.
