The Economic Growth Policy and International Stability with Short-run Migration

首先，在假设世界上只有两个国家的前提下，构建了一个简单的动态国际宏观经济模型。国际上没有资本流动，只有发展中国家的劳动力流动。对这些模型的基本分析使用经济增长理论的框架。在最简单的情况下，国际劳动力流动发生在两国之间的工资率差距，这是最有可能的情况下，经济国家作为一对夫妇的资本每劳动力和工资率将没有动态均衡。在这种情况下，人均劳动力资本将是不稳定的，制度参数对动态过程的影响更大。不稳定的经济增长对发展中国家有利，对发达国家不利。在这些参数上的经济政策仍然有一点可能使增长过程稳定。其次，通过更具体地重新拟订关于生产技术和人口动态的模型，不仅考虑到各国之间工资的国际差距，而且考虑到各国之间就业机会的国际差距。在这种情况下，发达国家的人均劳动力资本和访问工人率的经济状态很可能会出现动态不稳定或没有动态均衡。即使考虑到日本经济的主要趋势，这一结果也没有改变。因此，用合适的数据进行动态图形和数值动态分析几乎没有用处。国际增长几乎是动态不稳定的，制度参数可以软化每种动态模型的动态不稳定性。

Firstly, a simple model of dynamic and international macro-economy is constructed on the supposition that only two countries exist in the world. And it is supposed that there is no capital mobility but labor mobility come only from the developing country internationally. Basic analyses of such models use the framework of economic growth theory.In the simplest case that international labor mobility takes place by the gap of wage rate between the two countries, it is the most possible case that the economic state as a couple of capital per labor and wage rate will have no dynamic equilibrium. In this case capital per labor will be instable and institutional parameters have larger effects upon the dynamic processes. The instable economic growth is advantageous to the developing country but disadvantageous to the advanced country. The economic policy on those parameters still has a little possibility to make the growth processes to be stable.Next, by reformulating the model more specifically about production techniques and population dynamics, international gaps of not only wages but also employment opportunities between the countries are taken into account. In such a case, the economic state of capital per labor and visited workers rate in the advanced country will have much possibly dynamic instability or no dynamic equilibrium. These results are not changed even taking account of the main tendencies of Japanese economy. So, the dynamic graphical and numerical dynamic analyses with suitable data will have little or no usefulness.The international growth will almost instable dynamically, and institutional parameters can soften the dynamic instabilities of each dynamic model.
