As concerns about pollution and climate change have become more central in public discourse, shopping with reusable grocery bags has been strongly promoted as environmentally and socially conscious. In parallel, firms have joined policy makers in using a variety of initiatives to reduce the use of plastic bags. However, little is known about how these initiatives might alter consumers' in-store behavior. Using scanner panel data from a single California location of a major grocery chain, and completely controlling for consumer heterogeneity, we demonstrate that bringing your own bags simultaneously increases purchases of environmentally friendly as well as indulgent (hedonic) items. We use experimental methods to further demonstrate causality and to consider the effects of potential moderators. These findings have implications for decisions related to product pricing, placement and assortment, store layout, and the choice of strategies to increase the use of reusable bags.

In this paper, I examine the relation between Integrated Reporting (IR) and the composition of a firm's investor base. I hypothesize and find that firms that practice IR have a more long-term oriented investor base with more dedicated and fewer transient investors. This result is more pronounced for firms with high growth opportunities, not controlled by a family, operating in 'sin' industries, and exhibiting commitment to IR. I find that the results are robust to the inclusion of firm fixed effects, controls for the quantity of sustainability disclosure, and alternative ways of measuring IR. Moreover, I show that investor activism on environmental or social issues or a large number of concerns about a firm's environmental or social impact leads a firm to practice more IR and that this investor or crisis-induced IR affects the composition of a firm's investor base. Finally, firms that report more information about the different forms of capital or follow more closely the guiding principles as described in the IR Framework of the IIRC exhibit a more long-term oriented investor base.

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation, in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean technology can be difficult both because clean research must climb several rungs to catch up with dirty technology and because this gap discourages research effort directed towards clean technologies. Carbon taxes and research subsidies may nonetheless encourage production and innovation in clean technologies, though the transition will typically be slow. We characterize certain general properties of the transition path from dirty to clean technology. We then estimate the model using a combination of regression analysis on the relationship between R&D and patents, and simulated method of moments using microdata on employment, production, R&D, firm growth, entry and exit from the US energy sector. The model's quantitative implications match a range of moments not targeted in the estimation quite well. We then characterize the optimal policy path implied by the model and our estimates. Optimal policy makes heavy use of research subsidies as well as carbon taxes. We use the model to evaluate the welfare consequences of a range of alternative policies.

The business case for acting sustainably is becoming increasingly compelling—reducing our global footprint to sustainable levels is the defining issue of our times, and it is one that can only be addressed with the active participation of the private sector. However, persuading well-established organizations to act in new ways is never easy. This book is designed to support business leaders and organizational scholars who are grappling with this challenge by pulling together leading-edge insights from some of the world's best researchers as to how organizational change in general—and sustainable change in particular—can be most effectively managed. The book begins by laying out the economic case for change, while subsequent chapters describe how leaders at firms such as Du Pont, IBM, and Cemex have transformed their organizations, exploring issues such as the role of the senior team and the ways in which firms shift their identities, build innovative cultures and processes, and begin to change the world around them. Business leaders will find the book a source of both powerful examples and immediately actionable ideas, while scholars will be deeply intrigued by the insights that emerge from the cross cutting exploration of one of the toughest challenges our society has ever faced.

By 2014, IKEA Group was the largest home furnishing company, with EUR28.5 billion of sales, and planned to reach EUR50 billion by 2020, mainly from emerging markets. At the same time, IKEA Group had adopted in 2012 a new sustainability strategy that focused the company's efforts on its entire value chain from its raw materials sourcing to the lifestyle of its end consumers. The plan especially centered on wood, which represented 60% of IKEA Group's total procurement in volume and constituted a key lever for the company to increase its positive impact on sustainability. IKEA Group Management therefore had to decide how to manage its portfolio of wood sustainability initiatives, especially in the context of the company's aggressive growth plan.
