Total output in an economy increases when each person specializes because each person focuses on producing the good or service in which they have a comparative advantage, so the same resources generate more total output.

Direct exam-style answer

For the multiple‑choice phrasing:

“Total output in an economy increases when each person specializes because…”

The best answer is: Because each person spends more time producing the product in which they have a comparative advantage.

Why specialization raises total output

When people specialize:

  • They concentrate on tasks they are relatively best at (comparative advantage), so opportunity cost is minimized and efficiency rises.
  • Repetition builds skill and speed, so productivity per worker increases.
  • Firms can introduce better tools, processes, and technologies tailored to specific tasks, further boosting output.

Together, this means more goods and services are produced overall, even if total resources (workers, machines, time) stay the same.

Simple illustration

Imagine two people, Alex and Sam, who both can cook and write code.

  • Alex codes faster than Sam and is only slightly worse at cooking.
  • Sam cooks much better than Alex but codes slowly.

If each splits time 50–50 between cooking and coding, both tasks are done, but not very efficiently. If Alex specializes in coding and Sam specializes in cooking, then:

  • More total lines of code are written (Alex does all the coding, where Alex has comparative advantage).
  • More and better meals are cooked (Sam focuses where Sam is relatively best).

Total output of meals plus code rises, which is exactly what happens in an economy when individuals, firms, or countries specialize according to comparative advantage.

SEO-style meta description

Total output in an economy increases when each person specializes because specialization based on comparative advantage boosts efficiency, productivity, and innovation, leading to higher overall production and economic growth.

TL;DR:
Total output rises with specialization because people focus on producing what they are relatively best at (comparative advantage), so the same resources generate more goods and services overall.
