| Research Abstract |
Conventional theory of industrial organization discusses monopolistic product markets by assuming that factor prices, such as wage rate, are determined in a perfectly competitive market. On the other hand, conventional labor economics discusses imperfect labor markets by assuming that product prices are determined in a perfectly competitive market. However, since factor and product markets generally violate the assumption of perfect competition, the discussion of profit margins requires the incorporation of the special features of these markets. Given these arguments, this research project empirically examines the profit margins for Japanese manufacturing sector. We first studied the dynamic relationship among profit margins, market power, and product-life cycle in the DRAM industry, where Japanese firms have been playing an important role. Then we empirically analyzed the relationship between profit and firm growth for 1633 Japanese manufacturing firms.
