“Synchronized job transfer and task-specific human capital”

Journal of the Japanese and International Economies,vol.56, June 2020(査読有)

Abstract:Recent evidence suggests that frequent and broad lateral transfers increase the possibility of promotion. A question is how firms  save the costs of these frequent lateral transfers given the existence of job-specific skills. This paper proposes a new theory of the  transition across jobs based on the assumption that each job consists of tasks and that each of these tasks require specific skills. This  shows that firms synchronize the promotions and lateral transfers of their employees to reduce the cost of transferring to the employee those task-specific skills required for a new position. We find that this unique prediction is broadly supported by a large personnel data  set  in Japan.

“A New Geography of Civil War: A Machine Learning Approach to Measuring the Zones of Armed Conflicts”

forthcoming in Political Science Research and Methods.(査読有)(accepted in Feb 2020)

Abstract: By using a machine learning method, so-called one-class support vector machine, I create a new dataset of conflict zones. A replication of Daskin and Pringle (2018, Nature) with the new dataset indicates that the effect of civil war on mammal populations is much smaller than the original estimate.

“The Environmental Costs of Civil War: A Synthetic Comparison of the Congolese Forests with and without the Great War of Africa”

forthcoming in The Journal of Politics.(査読有)(accepted in Mar 2019)

Abstract: I conduct one of the first assessments about the environmental costs of civil war. I apply a synthetic control method to analyze deforestation in the Democratic Republic of the Congo. The analysis indicates that the Great War of Africa in the DRC resulted in the decrease of forest by 1.61%, which amounts to the entire territory of Belgium.
