Supply-side policies target structural economic issues

Steps:

• Assess problems: low inflation allows expansion, but high unemployment signals structural inefficiencies; BOP deficit indicates poor competitiveness.
• Match to long-run solutions: supply-side policies boost productivity and efficiency to address root causes.
• Evaluate impacts: improved efficiency reduces unemployment via better job creation and fixes BOP by enhancing export competitiveness.
• Confirm recommendation: advisor prioritizes sustainable, multi-issue fixes over short-term demand tweaks.

Why A is correct:

• Supply-side policies increase potential output (Y = f(L, K, Tech)), reducing natural unemployment rate and improving net exports via lower costs/higher productivity.

Why the others are wrong:

• B: Revaluation appreciates currency, raising export prices and worsening BOP deficit while risking higher unemployment from reduced AD.
• C: Higher direct taxes contract AD (C + I + G + (X-M) falls), exacerbating unemployment and low inflation without directly aiding BOP.
• D: Targeting higher inflation via demand stimulus boosts short-run output but ignores structural BOP issues and risks overheating without efficiency gains.

Final answer: A
