Our research investigates the mechanism of the movements of labor shares in Japanese economy, and particularly clarifies the phenomena since late 90's, implying rising income inequalities and declining aggregate labor shares. Specifically, we investigate the effects of demand for goods, deregulations in goods and labor markets, skill-biased technical change and capital accumulation and explore the role of asymmetries of factor substitutabilities between capital, skilled and unskilled labor. Especially, we explore the role of capital-skill complementarity structure which implies that the elasticity of substitution between capital and unskilled labor is larger than that between capital and skilled labor capturing one specific aspect of the newly technological progress in the production side in the medium and the long run perspective.We show that in the imperfect competitive market framework having Keynesian and classical features, income inequalities between skilled and unskilled labor c … More ountercyclically move and aggregate labor shares procyclically fluctuate under capital-skill complementarity structure. This means that in recession, income inequalities enlarge and aggregate labor shares decline. Furthermore, deregulations in the goods and labor markets are likely to create widening income inequalities and declining labor shares. We also shows that even in the competitive market framework, under some capital-skill complementarity structures, income inequalities enlarge and aggregate labor shares decline in the process of skill-biased technical change and capital accumulation. When labor mobility occurs, however, capital accumulation reinforces rising income inequalities and declining aggregate labor shares. Moreover we demonstrate that in labor mobility case, capital-sill complementarity structures are likely to enlarge aggregate elasticity of substitution between capital and overall labor which tends to promote per capita income in the steady state in the growing economy.

我们的研究调查了日本经济中劳动力份额的机制，尤其阐明了自90年代后期以来的现象，这意味着收入不平等增长并减少了总体劳动力份额。具体而言，我们调查了对商品需求，商品和劳动力市场上的放松管制的影响，技能偏见的技术变革和资本积累的影响，并探讨了资本，熟练和非熟练劳动力之间因素可替代性的不对称作用。尤其是，我们探讨了资本技能互补性结构的作用，这意味着资本和无技术之间的替代性弹性大于资本和熟练劳动之间的替代性，捕获了媒体中新技术进步的一个特定方面，而长期以来的角度以及长期以来的观点。我们表明，在不完美的市场框架之间，具有不完善的市场框架，熟练的熟练和熟练的熟练范围，凯旋式和不完美的市场框架。在资本技能互补性结构下，劳动力份额的总体份额会波动。这意味着在衰退中，收入不平等扩大和总体劳动力份额下降。此外，商品和劳动力市场的放松管制可能会造成扩大收入不平等和劳动力份额的下降。我们还表明，即使在竞争性的市场框架中，在某些资本技能互补性结构下，收入不平等扩大并在技能偏见的技术变革和资本积累的过程中扩大和总体劳动力份额下降。然而，当劳动力流动性发生时，资本积累会加剧收入不平等的不平等现象和劳动力份额的下降。此外，我们证明，在劳动力流动性案例中，资本式互补性结构可能会扩大资本和整体劳动力之间替代的总体弹性，这倾向于在不断增长的经济中促进稳态的人均收入。较少的
