Consider two countries I and II producing two commodities A and B. There is only one factor of production, that is, Labour hours. The table below gives labour hours required by each country to produce a unit of commodities A and B.
Labour hours needed to produce a unit of
| Country | Commodity A | Commodity B |
| I | ||
| II |
To analyze the situation of two countries, I and II, producing two commodities, A and B, with labor hours as the only factor of production, we can explore this scenario using the concept of comparative advantage, a core principle in microeconomics.
In this model, labor hours represent the amount of time it takes for a worker to produce one unit of a commodity. The production possibilities in each country are constrained by the number of labor hours available. By examining the labor hours needed to produce each commodity, we can determine the opportunity cost of producing one good over the other, which ultimately allows us to understand which country has a comparative advantage in producing which good.
Assuming that the table provides the necessary labor hours to produce commodities A and B in countries I and II, we can start by comparing the opportunity costs of producing A and B in each country.
Let’s assume the following data for labor hours needed:
