What does labor productivity measure in economics?

• A. Total value of goods and services produced within a country's borders in a year
• B. The total income earned by residents and businesses
• C. The amount of output produced per unit of labor input
• D. The rank of passports by visa-free destinations

Answer: (C)

Labor productivity measures how much output is produced for each unit of labor used—usually per hour worked. It tells you how efficiently workers convert time and effort into goods and services. In practice, you compare total production, like GDP, to the amount of labor that went into producing it. If output rises while hours worked stay the same, productivity goes up; if hours rise without more output, productivity falls. This measure matters because higher productivity means more can be produced with the same number of workers, helping explain why living standards can improve over time. Note that total production (GDP) looks at overall size, not efficiency per worker, while total income and passport rankings don’t capture how much each unit of labor contributes. Therefore, the best description is: output per unit of labor input.
