This paper investigates teleworker efficiency in Japan in the COVID-19 era by using unique survey data on telework. Many Japanese workers started teleworking during the pandemic and found both benefits as well as impediments. Overall, we find that telework experience and the work environment (e.g., having clearly specified tasks and a flexible working system), changes in work–life balance (e.g., working time), and good mental health improves teleworker efficiency.

The need for developed countries to take a lead in the global fight against climate change is generally acknowledged and was intrinsic to the 2015 Paris climate change agreement. An understanding of the way in which environmental policy in advanced nations has developed and which policies have had a significant impact on the reduction in the emissions of various pollutants may yield important policy prescriptions relevant to the current climate change negotiations. In this paper we consider how Japan's little-known environmental interest rate policy and voluntary pollution control agreements contributed to Japan's ecological modernization and how these policies compare with the more traditional regulatory approach. Our results show that Japan's use of an environmental interest rate policy was an effective policy as a complement to the more traditional regulatory approach.

In this paper, we study the waste haven hypothesis, which predicts that waste materials will be exported from high-income developed countries with stringent environmental regulations to developing countries with less rigorous environmental protection. Using data on Japanese export of recyclable waste resources (plastic waste, waste paper, iron and steel scrap, and nonferrous metal scraps), we find evidence from our econometric analysis that Asian countries provide a waste haven for Japan. In particular, Japan exports waste materials to Asian countries with low per capita incomes and large markets. We suggest that environmental regulation should be tightened to reduce waste trade in Asia.
