Corporate Environmental and Economic Performance of Japanese Manufacturing Firms: Empirical Study for Sustainable Development

This study examines the relationship between environmental performance and economic performance in Japanese manufacturing firms. The environmental performance indicators include CO₂ emissions and the aggregate toxic risk associated with chemical emissions relative to sales. Return on assets (ROA) is used as an indicator of economic performance. We demonstrate that there is a significant inverted U‐shaped relationship between ROA and environmental performance calculated by aggregated toxic risk. We also find that the environmental performance increases ROA through both returns on sales and improved capital turnover. However, we observe a significant positive relationship between financial performance and environmental performance based on CO₂ emissions. These findings may provide evidence for the consequences of firms' environmental behavior and sustainable development. Copyright © 2012 John Wiley & Sons, Ltd and ERP Environment.     

An empirical re-evaluation of wealth effect in Japanese household behavior

This study investigates empirically the role of wealth in the behavior of Japanese households from two standpoints. One is concerned with what types of wealth are relevant in consumption decision by households. The other is which component of consumption spending is affected by wealth. We find that the liquid financial wealth appears as a significant explanatory variable in expenditure function of many commodity groups as well as total consumption. It turns out that variations of liquid wealth are responsible for about one third of the change in aggregate consumption in the boom period starting from the middle of 1980s.     

Asymmetric persistence in GDP? A deeper look at depth

If an economic time series behaves asymmetrically, then an interpretation of economic fluctuations based on linear time-series models could be misleading. Beaudry and Koop (1993) recently argued that for post-war US GDP data there exists a statistically significant difference in persistence between negative and positive shocks. We demonstrate that their test has two pitfalls: First, the t-statistic for testing asymmetry in persistence does not have a conventional interpretation. Second, a highly significant t-value may come from sources different from asymmetry. Using international data, we investigate for the presence of asymmetric persistence across the G-7 countries.     

Stock market liberalization and international risk sharing

This paper empirically examines what macroeconomic risks are shared (or not shared) internationally after stock market liberalization in several developing countries. To address this issue, we incorporate an international asset pricing model into a non-linear structural vector autoregression (VAR) system that identifies various sources of macroeconomic risks. We find that most of the risks corresponding to exogenous financial market shocks are surprisingly well shared, although other macroeconomic risks associated with exogenous shocks to output, inflation and monetary policies are not fully shared across countries. Our results suggest that one of the main benefits from stock market liberalization is to allow the countries studied in this paper to better hedge against exogenous and idiosyncratic financial market risks, and stock market liberalization needs to be accompanied by other measures of economic integration in order to achieve the full benefits of international risk sharing.
