By making full use of large quantities of unique personnel data which are available from both employee lists I obtained and published lists of company employees, I analyzed the in-house carrier development system of white-collar workers in major Japanese companies from economic viewpoints.

I particularly focused on gaining clear insights for a long-term selection process and in-house career development which can be seen over a long span of the employment period by making empirical analyses to correlate promotion with job assignment, which have not been fully attempted by previous research yet.

I have been continuing the foregoing research .In addition, I look at how the problems that many Japanese companies are facing today, such as merger and acquisition, personnel system reform, and changes in environment surrounding in-house human resource management influence employees’ compensation and career development, and the cooperate performance of companies.

Furthermore, for conducting collaborative research, I integrate the incentive effect of a discontinuous and nonlinear compensation scheme and the influence of ethnicity on customer-salesperson transactions by using the transaction data provided by North American auto dealerships.
