Analyzing Comparative Cost Theory's Static Nature

This section evaluates the assertion that the Comparative Cost Theory is static and the reason provided.

Assertion (A) Analysis: Static Character

The Assertion (A) states that the Comparative Cost Theory is static. This is generally considered correct because the classical theory, particularly the model developed by David Ricardo, makes several simplifying assumptions that do not account for changes over time:

• Fixed technology: Assumes production methods remain constant.
• Fixed factor supplies: The amounts of land, labor, and capital are assumed to be fixed.
• No changes in tastes or demand: Consumer preferences are static.
• Perfect factor mobility within countries, immobility between countries.

Because these elements are assumed not to change, the pattern of comparative advantage and trade predicted by the theory remains fixed, hence its static character.

Reason (R) Analysis: Fixed Factor Supplies

The Reason (R) states that the theory is based on fixed supplies of factors of production. This is also correct. The concept of comparative advantage hinges on differences in opportunity costs between countries. These opportunity costs are derived from the relative productivities of factors (like labor) in producing different goods, given the fixed amounts and proportions of factors available within each country. If factor supplies were variable or changed significantly, the production possibilities and thus the comparative costs would shift.

Relationship Between Assertion and Reason

The reason (fixed factor supplies) directly supports the assertion (static character). The assumption of fixed factors of production is a key reason why the comparative cost model does not dynamically adjust to changes. Therefore, the fixed nature of factor supplies is a fundamental element contributing to the static nature of the theory.

Conclusion: Both Assertion (A) and Reason (R) are correct, and Reason (R) provides a valid explanation for Assertion (A).
