No, having absolute advantages in all products does not necessarily mean having comparative advantages in all products. The concepts of absolute advantage and comparative advantage are distinct and have different implications.
Absolute advantage refers to a situation where a person, country, or entity can produce a good or service more efficiently or with higher productivity than others. It means they can produce more output using the same amount of resources or produce the same output using fewer resources compared to others.
Comparative advantage, on the other hand, considers the opportunity cost of producing a particular good or service. It relates to the relative efficiency or productivity in producing different goods compared to others. Even if someone has an absolute advantage in all products, they may still have a comparative advantage in specific products where their efficiency or opportunity cost is relatively lower compared to others.
The concept of comparative advantage suggests that it is beneficial for individuals, countries, or entities to specialize in producing and exporting goods or services where they have a lower opportunity cost. By doing so, they can maximize their overall productivity and benefit from trading with others who have different comparative advantages.
Therefore, having absolute advantages in all products does not imply comparative advantages in all products. It is possible for someone to have absolute advantages in all products but still have a comparative advantage in specific products where their efficiency or productivity is relatively higher compared to others.
