Verification of Effectiveness of Employment Information on Productivity Performance in Japanese Companies

Ryohei Sotome and Masako Takahashi
Abstract—The impact of employment systems on productivity performance is a crucial management issue not limited to labor-intensive enterprises. Japanese companies do not recognize the importance of employment information. In order for executives to understand its importance, this research verifies the effectiveness of employment information on productivity performance in Japanese companies. In addition, influential information categories and indicators with respect to productivity performance are identified. DEA and DEA Malmquist Indices are applied so as to define productivity performance. As a result, the companies, which actively engage in disclosing employment information, tend to be productive. Furthermore, the model including quantitative indicators calculated from employment information is more explanatory than the model including solely financial indicators. In particular, turnover rate, average length of service and average annual salary are the most influential indicators. Contrary to the philosophy of long-term employment, higher liquidity is preferred in Japanese companies.

Index Terms—DEA, employment information, Japanese employment system, Malmquist index, productivity
