When companies improve the sustainability of the natural environment: A study of large U.S. companies

In light of the call for companies to abandon current approaches to environmental management, this study adds to the environmental strategy literature and uses the evidence of competitive dynamics among companies to identify a mechanism by which companies invest in proactive environmental strategies and thereby improve the sustainability of the natural environment. An examination utilizing fixed effects regressions on a sample of large U.S.‐based companies reveal that even after controlling the number, environmental and financial performance of leading (environmental) companies, laggard (environmental) companies are more likely to invest in proactive environmental strategies when their leading peers display higher sustainability orientations. Neither the expectation of government regulation nor social movement pressure was found to be influential in this relationship. Therefore, the future dominance of companies' investments in the sustainability of the natural environment will be driven by companies themselves as long as competitive advantages are expected.     

Internet of Things and Big Data as enablers for business digitalization strategies

Digitization blurs the lines between technology and management, facilitating new business models built upon the concepts, methods and tools of the digital environment. The purpose of this study is to investigate the role of the Internet of Things (IoT) and Big Data in terms of how businesses manage their digital transformation. The paper argues that the outbreak of IoT and Big Data has resulted in a mass of disorganized knowledge. In order to make sense of the noise, a literature review was carried out to examine the studies, published in the last decade (2008–2019), that analyzed both the Internet of Things and Big Data. The results show that IoT and Big Data are predominantly reengineering factors for business processes, products and services; however, a lack of widespread knowledge and adoption has led research to evolve into multiple, yet inconsistent paths. The study offers interesting implications for managers and marketers, highlighting how the digital transformation enabled by IoT and Big Data can positively impact many facets of business. By treating IoT and Big Data as faces of the same coin, this study also sheds light on current challenges and opportunities, with the hope of informing future research and practice.

Contrarian Investment in the Dutch Stock Market

The efficient markets hypothesis states that at any times security prices fully reflect all available information. Contrarian investment strategies do not recognize the efficiency of capital markets. They call for buying undervalued stocks, i.e. stocks with a low price relative to their fundamentals. The idea behind such a strategy is to take advantage of the extrapolation behaviour of naive investors. Using a fresh and extensive data set from the Dutch stock market, we found that these strategies yield an outperformance without a higher risk. Our results make it hard to maintain the efficient market hypothesis.
