Does financial development stimulate environmental sustainability? Evidence from a panel study of 115 countries

This paper investigates the moderation effect of financial development (FD) on the environmental Kuznets curve (EKC). Using comprehensive panel data of 115 countries spanning the 1990–2016 period and dividing the countries into different income groups, the researcher found systematic differences in the relationship between significant indicators of environmental degradation and economic growth. More specifically, the interaction effect of FD on the relationship between gross domestic product (GDP) growth and CO₂ emissions are positive; nevertheless, the interaction effect of FD on the relationship between GDP squared and CO₂ emissions become negative for all income groups and therefore supports the EKC. Moreover, the interaction effect of FD is negative on the relationship of GDP with both CH₄ and PM_2.5 emissions in the middle‐income groups, whereas the interaction effect of FD on the relationship between GDP squared and PM_2.5 emissions are negative for the high‐income group. Our results suggest that FD can reduce environmental degradation without adversely impacting on growth.

Board gender diversity and environmental performance: An industries perspective

This study investigates whether gender diversity on the board of directors in the United States is associated with firms' environmental performance. Under the theoretical framework of resource dependence theory, we argue that gender diversity brings a greater variety of skills to the board. Diversity allows for a healthy mix of knowledge and experience to improve the decision‐making process of the board. Using propensity score matching and controlling for endogeneity, this study uses a more rigorous statistical model than previous work. It also uses content analysis of directors' biographies to provide evidence of the role that gender diversity plays. We find gender diversity is positively associated with firms' environmental performance scores primarily in the more environmentally impacting industries. Therefore, our research provides valuable direction for those firms working to improve both their boards' gender diversity and their environmental performance. Our findings also offer insight into the mixed results of previous studies.

The influence of the competitive landscape on cross-functional interactions between procurement and engineering

This study assesses the extent to which a firm's external environment shapes the cross-functional interactions between procurement and engineering, utilizing an embedded multiple-case study methodology. In summary, we found that high environmental ambiguity discourages procurement-engineering mutual understanding. High environmental uncertainty with moderate ambiguity, on the other hand, appears to foster both mutual understanding and inter-functional collaboration. Overall, procurement personnel are more optimistic than engineering personnel regarding the performance results stemming from cross-functional integration. Additionally, increasing job tenure for procurement personnel leads to a higher level of perceived integration with engineering, while engineers with longer job tenure report see less value in collaborating with procurement, often creating an asymmetric power distribution with engineering taking a dominating role.

SMEs and the Potential for A Collaborative Path to Environmental Responsibility

Globally, the potential for small and medium‐sized enterprises (SMEs) to collectively impact negatively on the environment is great. Therefore, the adoption, and maintenance, of environmentally responsible practices by this group of firms is especially critical. Studies of environmental practices successfully implemented by small firms have revealed that relationships with other firms, or other organizations, can contribute to greater awareness of the benefits of such activities and, therefore, enhance the possibility of environmental engagement. Collaborative relationships may provide opportunities for SMEs to overcome some of the barriers to implementing environmental initiatives associated with their size, and/or associated characteristics. This paper focuses on attitudes of SME owner‐managers to a variety of environmental issues (including regulation and voluntary standards), and to collaborating with other firms (in either a formal or informal sense). The data this paper draws upon are from two waves of an ongoing longitudinal survey of New Zealand SMEs. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment

Pollution and informal economy

In this study, we investigate the relationship between the size of the informal economy and the level of environmental pollution/energy use. To this end, we first use different indicators of environmental pollution along with a measure of energy use intensity in a panel dataset consisting of 152 countries over the period 1999–2009 and empirically examine the relationship between pollution and the shadow economy. The estimation results show that there is an inverse-U relationship between the size of the informal economy and environmental pollution, that is, small and large sizes of the informal economy are associated with lower environmental pollution and medium levels of informality are associated with higher levels of environmental pollution. Next, we build a two sector dynamic general equilibrium model to suggest an economic mechanism for this observation. Our model identifies two channels through which informality might affect environmental pollution: The scale effect, whereby a larger (smaller) informal economy size is associated with a lower (higher) level of environmental pollution, and the deregulation effect, whereby a larger (smaller) informal economy is associated with higher (lower) pollution levels. As these two effects work in opposite directions, the changing relative strength of one with respect to the informal sector size creates the inverted-U relationship between pollution indicators and informality.     

Supplier dependence asymmetry and investment in innovation: The role of psychological uncertainty

A key source of competitive advantage for large firms accrues from investments in innovative products and processes by their suppliers, incentivized by a positive relationship climate. A fundamental hindrance lies in a condition that commonly characterizes buyer-supplier relationships: asymmetric levels of dependence between business partners. Such asymmetry has been shown to be detrimental to the relationship, enhancing the likelihood of conflict, and negatively impacting the performance of the more dependent party. Considering that such dependence asymmetry is likely to persist, large buyers face the challenge of promoting a relationship environment that provides an incentive for suppliers to invest in innovation. In this study, we propose that large, dominant buyers can influence suppliers' intentions and behaviors by mitigating the effects of their perceived riskiness and ambiguity that emerge from a situation of dependence asymmetry. Specifically, using the lens of resource dependence theory, we investigate the effects of these two psychological dimensions of uncertainty on a supplier's trust, commitment, and willingness to invest in innovation, as well as the moderating effect of a buyer's information sharing in shaping a supplier's perceived uncertainty. The model is tested with a scenario-based experiment and results are corroborated by interviews with experienced managers of retail suppliers. Our findings indicate that a supplier's dependence on a large buyer increases its perception of ambiguity and riskiness in the relationship, negatively impacting its trust, commitment, and willingness to invest in innovation. However, a buyer who shares relevant and timely information with the supplier mitigates its perceived uncertainty, promoting the supplier's positive attitudes towards the buyer and incentivizing innovation. Sharing operational and strategic information such as point-of-sales data, sales forecasts, or strategic plans, becomes a valuable strategy to powerful buyers in the pursuit of becoming a preferred customer and enhancing a supplier's resource mobilization towards the relationship.
