Incorporating explicitly division of labor into a two-country general oligopolistic equilibrium model, we examine the firm productivity effect of trade liberalization and its welfare implication. We show that a tariff reduction increases the firm productivity of the trading industries but decreases that of the non-trading industries. An expansion of the trading industries, in contrast, decreases the firm productivity of both the trading and non-trading industries. We then find that a tariff reduction necessarily reduces welfare while the welfare effect of expansion of trading industries is ambiguous.
