Which statement is false regarding macroeconomic policy views as summarized in the material?

• A. Early Keynesians downplayed the effectiveness of monetary as opposed to fiscal policy during downturns.
• B. The natural rate hypothesis sharply limits what macroeconomic policy can achieve.
• C. Monetarists argued that discretionary monetary policy does more harm than good.
• D. Concerns about a political business cycle suggest that fiscal and monetary policy should be fully discretionary.

Answer: (D)

Macroeconomic policy views emphasize how policy choices interact with incentives, credibility, and the timing of effects. Early Keynesians argued that fiscal policy could be a powerful tool to offset downturns, while monetary policy alone might not be enough in a weak demand environment. The natural rate hypothesis adds that, in the long run, policy cannot permanently reduce unemployment below the natural rate without causing higher inflation, so persistent gains in real output are unlikely. Monetarists push for predictable, rule-based monetary growth rather than discretionary moves, because discretion can introduce instability and misperceptions that worsen cycles. Concerns about a political business cycle highlight that policymakers may be tempted to manipulate fiscal or monetary policy to influence elections, which can undermine credibility and destabilize inflation and output. This view generally supports constraints on discretion—such as rules or independent institutions—to curb political motives and improve policy credibility. Therefore, the statement proposing fully discretionary policy in light of political business cycle concerns does not fit with these established perspectives.
