After working at a private research institute in Tokyo, Professor Yamamoto completed his Ph.D. in Economics at Keio University in 2008. His major research interest is environmental and resource economics especially in the eld of waste management and recycling.
Professor Yamamoto’s work has been published in academic journals including Journal of Environmental Economics and Management, Resource and Energy Economics, Regional Science and Urban Economics and Science of the Total Environment. He is also a co-editor of a book, Economics of Waste Management in East Asia (Routledge, 2016).
Professor Yamamoto has been committed to real world’s policy making process through his work in numerous government committees to revise recycling laws in Japan. He is also an expert member of Technical Committee 323 (circular economy) in the International Organization for Standardization (ISO).

主旨
In recent years, increasing attention has been paid to plastic waste, but in most cases, only household plastic waste has received attention. Knowing that the amount of plastic waste from households and that from manufacturing are almost the same in Japan, we focus on the change in plastic waste emissions from manufacturing from 2004 to 2018.
Following the novel method of Levinson (2015, JAERE), we decompose the emissions of plastic waste into scale effects, composition effects and (in)direct technique effects. This first application of the method in waste generation shows that the composition effect has very limited contribution to the decrease of plastic waste, if not increased pollution emissions. The result in our analysis is rather similar to Brunel (2017, ERE) and Cole and Zhang (2019, Econ. Letts.) although their targets are CO2 and air pollution in EU and China.
Before presenting my original research above, I would like to compare some key indicators in waste and recycling among OECD countries and explain the characteristics of Japanese version of circular economy in contrast to European Union’s.
