摘要

This paper addresses two important questions: 1.Does trade liberalization render a merger more desirable? 2. Does trade liberalization move desirability and profitability in the same direction?

This paper has two main findings: 1. Trade liberalization increases the desirability of mergers with large merger-induced reductions in marginal cost. 2. Exists a range of intermediate levels of marginal cost savings from merger such that the trade liberalization increases the desirability of merger at sufficiently low tariff levels.

The impact of marginal trade liberalization on the desirability of merger fails to be a reliable indicator of the same when tariff changes are non-marginal. This paper also shows that it is possible for the competition bureau by using the tariff level, which is directly observable, when formulating optimal merger policy in the face of trade liberalization.
