In economics a country's factor endowment is commonly understood as the amount of land, labor, capital, and entrepreneurship that a country possesses and can exploit for manufacturing. Countries with a large endowment of resources tend to be more prosperous than those with a small endowment, all other things being equal. The development of sound institutions to access and equitably distribute these resources, however, is necessary in order for a country to obtain the greatest benefit from its factor endowment.
Factor endowment theory is made up of two important theorems namely,
Heckscher-Ohlin Theorem
Factor Price Equalization
Heckscher-Ohlin Theorem states- "A capital-abundant country will export the capital-intensive good, while the labor-abundant country will export the labor-intensive good." The critical assumption of the Heckscher–Ohlin model is that the two countries are identical, except for the difference in resource endowments. This also implies that the aggregate preferences are the same. The relative abundance in capital will cause the capital-abundant country to produce the capital-intensive good cheaper than the labor-abundant country and vice versa.
Factor Price Equalization states that the relative prices for two identical factors of production in the same market will eventually equal each other because of competition. The price for each single factor need not become equal, but relative factors will. Whichever factor receives the lowest price before two countries integrate economically and effectively become one market will therefore tend to become more expensive relative to other factors in the economy, while those with the highest price will tend to become cheaper. An often-cited example of factor price equalization is wages. When two countries enter a free trade agreement, wages for identical jobs in both countries tend to approach each other.
