Associate Professor Jun Nakabayashi, Faculty of Economics, Kinki University, and others are investigating the relationship between the so-called "Amakudari," in which civil servants re-employed in private companies, and the probability that a company will win a public project.As a result, it was found that the probability of winning a bid for a public project increases by an average of 1 points (the average probability of winning a bid is 0.7%) for each company that accepts Amakudari.
The data used for the analysis are the construction work bid data published by the Ministry of Land, Infrastructure, Transport and Tourism and the "Annual Report on Approval of Employment for Commercial Companies" published by the National Personnel Authority from 2001 to 2004.For about 3 public works bids in which the contractors who accepted Amakudari participated during this period, we statistically analyzed how the probability of winning a bid for public works changed before and after the company accepted Amakudari.
As a result, it was found that the winning bid probability increased immediately after accepting the Amakudari, and the winning bid probability increased by 1 points on average each time one person accepted the Amakudari.
In addition, when the same analysis was conducted by dividing the retired civil servants into clerical and technical staff, there was no difference in the effect of increasing the probability of winning bids between the two.This suggests that the technical knowledge of retired civil servants does not increase the probability of winning bids, but that the probability of winning bids increases in return for accepting Amakudari.
It can be said that this study highlights the possibility that Amakudari threatens the soundness of the market economy.The research results will be submitted to academic journals in Japan and overseas in the future.
