如何看待麦克杜格尔模型的基本理念?

答案

参考答案:

麦克杜格尔模型是麦克杜格尔在1960年提出来,后经肯普发展,用于分析国际资本流动的一般理论模型,其分析的是国际资本流动对资本输出国、资本输入国及整个世界生产和国民收入分配的影响。麦克杜格尔和肯普认为,国际间不存在限制资本流动的因素,资本可以自由地从资本要素丰富的国家流向资本要素短缺的国家。资本流动的原因在于前者的资本价格低于后者。资本国际流动的结果将通过资本存量的调整使各国资本价格趋于均等,从而提高世界资源的利用率,增加世界各国的总产量和各国的福利。

虽然麦克杜格尔模型的假设较之现实生活要简单得多,且与显示生活有很大的反差,但是这个模型的理念确实是值得称道的,既国际投资能够同时增加资本输出输入国的收益,从而增加全世界的经济收益。
