摘要：It is widely argued that international arbitrage, or parallel trade (PT), trades off static against dynamic efficiency so that, compared with a national exhaustion regime of intellectual property rights, worldwide consumer surplus rises at the expense of R&D investment. We show that this common wisdom is rather the exception than the rule. Indeed, quality investment often rises under international exhaustion , since it strengthens vertical differentiation between the original product and parallel imports . In this case, there is no trade-off at all, so that encouraging PT improves welfare, or the reverse trade-off occurs where investment increases and consumer surplus declines, while PT has ambiguous welfare effects. We find that, when allowed to use dual pricing, the R&D firm artificially restores national exhaustion. We also find that the expected trade-off never occurs under non-linear pricing and w hen the foreign country is regulated, although in such cases welfare rises when PT is banned.
