U. s. exports are less capital-intensive than u. s. imports, despite the relative abundance of capital in the country. this is in opposition to the heckscher-ohlin theory and has been labelleda. a zero-sum game. b. leontief's paradox. c. a positive-sum game. d. samuelson's critique. e. a first-mover advantage.

The correct answer is option b.

Explanation:

According to the Heckscher-Ohlin theory, a capital abundant country specializes in capital intensive goods. Thus it produces capital intensive goods and exports them, and imports labor-intensive good.  

But this does not prove right in the case of the US. Being a capital intensive country it imports capital intensive goods and exports labor-intensive goods.  

This was proved by W. Leontief through empirical evidence. Thus, it is called the Leontief paradox.
