As the economist Jagdish Bhagwati points out, maintaining increased protections for, say, intellectual property may encourage research and innovation. At the same time, however, excessive IP protections can deter the proliferation of existing knowledge and the development of high-tech products.
应该指出，自由化确实包含了一些经济权衡，因为在某些领域，保护有助于实现重要目的。经济学家贾格迪什·巴格瓦蒂（Jagdish Bhagwati）指出，保持增加对（比如）知识产权的保护可以鼓励研究和创新。但是，与此同时，过度知识产权保护可能延缓现有知识的扩散和高科技产品的开发。比如，在制药行业，这一权衡就很难规避。尽管如此，巴格瓦蒂认为，对于总体贸易和资本流动而言，越自由越好。
