Two economic policymakers are debating their country's long-term strategy.

Policymaker A argues: "Our central bank's primary focus for the next decade should be to use its tools to achieve a stable 3% annual growth in real economic output. This is the most direct path to prosperity."

Policymaker B counters: "I disagree. Over the long run, our central bank has a much stronger ability to maintain a low and stable rate of inflation than it does to dictate a specific rate of real economic growth. We should focus our efforts there."

Evaluate these two positions. Which policymaker's argument is more consistent with the established long-run effects of central bank actions? Justify your reasoning.
