"Economic analysis has come up short of providing either theoretical or empirical grounds for assessing the overall effect of intellectual property law on economic welfare." -- 'The economic structure of intellectual property law'; Landes, Posner; 2003.

…(see: the standard economic model of it). If it is badly calibrated, the net effect is negative. And the current state of economic knowledge is that no-one knows whether it is set correctly (see: 'The economic structure of intellectual property law'; Landes, Posner; 2003. Conclusion, p422, s3.). When there is a whole big system, of various obvious costs, and you do not even know the net effect is positive, the sensible thing is to stop doing it…

……意味着拥有知识产权（IP）总体上有益这一点已经被充分证明。所以，与其说我们绝对需要它，倒很有可能完全没有它我们会过得更好。兰德斯和波斯纳是怎么说的？（出自《知识产权法的经济结构》；Landes, Posner；2003年，结论部分，第422页第3节）“经济学分析至今未能提供充分的理论或经验依据，来评估知识产权法的总体效果……”

……兰德斯和波斯纳怎么说？“经济学分析至今未能提供充分的理论或经验依据，来评估知识产权法对经济福利的总体效果。”——《知识产权法的经济结构》；Landes, Posner；2003年，结论部分，第422页第3节。这意味着我们根本不知道它总体上是否有利。难以置信吗？可事实就是如此。

……（参见：它的标准经济学模型）。如果校准不当，净效益就是负的。而目前的经济学认知现状是，没人知道它的设定是否正确（参见：《知识产权法的经济结构》；Landes, Posner；2003年，结论部分，第422页第3节）。当存在这么一个庞大的系统，伴随着各种显而易见的成本，而你甚至连净效益是否为正都不知道时，明智的做法就是别再这么干了……

正如兰德斯和波斯纳在《知识产权法的经济结构》（结论部分，第422页第3节，2003年）中所说：“经济学分析至今未能提供充分的理论或经验依据，来评估知识产权法对经济福利的总体效果。”……

……给你引一段好话：“经济学分析至今未能提供充分的理论或经验依据，来评估知识产权法对经济福利的总体效果。”——《知识产权法的经济结构》；Landes, Posner；2003年。（结论部分，第422页第3节。）兰德斯和波斯纳是该领域公认的正统权威，连他们都在告诉我们，我们甚至都不知道版权到底有没有带来任何好处。
