Mismatched solutions for types of unemployment

Steps:

• Define unemployment types: cyclical from economic downturns, frictional from job search transitions, structural from skill/location mismatches.
• Match solutions: cyclical needs demand boost like fiscal stimulus; frictional needs better job info; structural needs skill adaptation like retraining.
• Check each option: A fits cyclical via expansionary policy; B fits frictional by reducing search time; C mismatches structural with frictional solution; D fits structural directly.
• Identify incorrect pair as the one applying frictional fix to structural issue.

Why C is correct:

• Structural unemployment arises from skill mismatches, so advertising vacancies (a frictional solution) fails to address root causes like obsolete skills, per labor economics definitions.

Why the others are wrong:

• A: Raising government spending correctly stimulates demand to reduce cyclical unemployment, following Keynesian fiscal policy.
• B: Increasing advertising reduces frictional unemployment by improving job matching efficiency.
• D: Retraining workers directly resolves structural unemployment by updating skills for new industries.

Final answer: C
