The analysis of specific economic indexes suggests that the economic damage from the 2020 COVID-19 crisis (coronavirus pandemic, apparently first spread from Wuhan, China) may exceed that of the 2008 global financial crisis dating to around September 15, 2008. Thus, by comparing the first four months after these crises, the purpose of this study is...

In the Sustainable Development Goals (SDGs) adopted by the United Nations (UN), goal 12 (“ensure sustainable consumption and production [SCP] patterns”) has eight outcome targets (12.1–12.8) and three targets for the means of implementation (MoI) (12.a–12.c). This “SCP-via-SDGs” approach is a much narrower, specific concept based on historical agre...

Disasters often cause exogenous flow damage (i.e., the [hypothetical] difference in economic scale with and without a disaster in a certain period) to production (“supply constraint”). However, input‐output (IO) analysis (IOA) cannot usually consider it, because the Leontief quantity model (LQM) assumes that production is endogenous; the Ghosh quan...

From the perspective of material flow cost accounting (MFCA), which treats both material and financial flows within a company, this study proposes a corporate waste decomposition model to investigate the effects of material and financial factors on corporate waste generation. The proposed model decomposes waste into the material loss (waste ratio o...

This study compares the shadow price (marginal cost) and shadow value (total cost) of patent stock (as knowledge stock) in each of 92 countries between 1992 and 2010. Two specifications are considered in the data envelopment analysis approach. One specification considers population, capital, patent stock, energy use (four inputs), greenhouse gas (u...

This study investigated the relationship between corporate efficiency and corporate sustainability to determine whether firms concerned about environmental, social, and governance (ESG) issues can also be efficient and profitable. We applied data envelopment analysis to estimate corporate efficiency and investigated the nonlinear relationship betwe...

In recent years, material flow cost accounting (MFCA) has gradually been recognized in Asia by the standardization of ISO 14051 and 14052 and by the project of dissemination undertaken by the Asian Productivity Organization (APO). However, MFCA is still not used across the board. This study analyzes the characteristics of material flow (MF) managem...

Recent empirical studies often support the positive relationship between corporate environmental performance (CEP) in terms of carbon dioxide (CO2) and greenhouse gas (GHG) emissions and corporate financial performance (CFP). However, this depends on the measurements of CEP (the absolute and relative CEP) and CFP (accounting‐based and market‐based...

This study empirically examines the demographic determinants of car ownership in Japan between 1980 and 2009. Unique car cohort data, composed of the car age and 11 car types, at the prefectural level, is analyzed. The primary reason for examining the demographic determinants of car ownership in Japan is because Japan is projected to face radical d...

This study examines time-period and industry heterogeneity of innovation activity in Japan from 1964 to 2006 using patent data and non-consolidated firm data. This study focuses on the following three periods, based on changes of the Japanese patent system, in and non-manufacturing industries: (I) before 1976; (II) 1976–1987; and (III) after 1988....

Problem of water scarcity has been increasingly severe in China. Though industrial sectors play important role for the rapid economic growth, and they consumes water and discharge wastewater. The purpose of this study is to examine the efficiency of water use and wastewater discharge in comparison with those of other inputs and production output in...

Japan's fishery harvest peaked in the late 1980s. To limit the race for fish, each fisherman could be provided with specific catch limits in the form of individual transferable quotas (ITQs). The market for ITQs would also help remove the most inefficient fishers. In this article we estimate the potential cost reduction associated with catch limits...
