While firms' engagement with Corporate Social Responsibility has been associated with positive performance impacts, little is known about the incorporation of the United Nations 2030 Agenda into business practices. Precisely, although the literature suggests that firms are pursuing the Sustainable Development Goals (SDGs), there are limited insights on their strategy to implement them in the context of developing countries. To address this gap, we conducted a comprehensive large-scale investigation of 2030 Agenda adoption by Brazilian companies. Accordingly, the analysis of our multicase study reveals (1) variations on the business opportunities brought by the SDGs depending on the firm position in the value chain, (2) which SDGs and target stakeholders are addressed through corporate policies and practices, (3) the different ways firms embrace the SDGs to pursue ambidexterity. Our findings clarify how firms in the developing countries interpret the institutional pressures and assemble their internal resources to respond to the SDGs challenges. Boundary conditions and policy implications are further discussed.  相似文献

The ongoing COVID-19 pandemic has brought terrifying effects for labor markets all around the world. Just as we witness rapid changes in terms of the ways of working (working from home), we are also observing an increase in unemployment. The ways in which major corporations with international operations process their global talent management (GTM) already represents a challenge in relatively stable times and clearly, in a period of such great and sustained turbulence as current experienced, this task becomes still more difficult. Hence, our research aims to study the impact of GTM on the international performance of major companies during the COVID-19 pandemic period. To this end, we surveyed a sample of 59 large companies that act in external markets. Through recourse to multiple linear regressions, we conclude that GTM practices return positive impacts on levels of international performance. Our research returns theoretical implications in terms of the application of integrated GTM models and with the results of significant relevance to corporations operating internationally, and thus enabling them to better understand which strategic human resource management policies will return the best GTM results.  相似文献

This paper examines the impact of the 2016 election on substance use. One of Donald Trump's major campaign initiatives was to build a wall at the American/Mexican border, and he frequently made negative comments about various underrepresented groups. I hypothesize that this unorthodox rhetoric, coupled with Donald Trump's proposed policies during his campaign, created an exogenous shock of discrimination for women, and ethnic and racial minority groups when he was elected. The Behavioral Risk Factor Surveillance System dataset, which has a variety of health measures and demographic information compiled at the individual level, is utilized to empirically examine the hypothesis. I examine the average treatment effects of the election using a difference-in-differences estimation strategy. The results indicate that there has been an increase in cigarette use for Hispanic individuals. These results highlight the impact that discriminatory rhetoric by political leaders and public figures has on marginalized groups within society. Policy implications include new ways to target substance use by targeting discrimination.  相似文献

Some previous researchers have argued that trading strategies based on calendar spread time series momentum (STSM) can deliver significant returns (Szymanowska et al. 2014; Boons and Prado 2019), which, if true, is at odds with the efficient market hypothesis. These arguments however, do not exclude the unrealisable futures contract roll yield and are also affected by other empirical and statistical issues that may lead to misleading results. With more than 30 years of data, we investigate STSM in 22 US commodity futures markets. First, we assess whether past spread returns can predict future returns, a necessary condition for the existence of momentum. We find predictability to be very weak after correcting for the issues affecting prior research. Second, we implement STSM-based investment strategies. We compare STSM profits for individual markets and portfolios to profits generated by a simple long-only benchmark strategy that does not require any predictability. STSM does not generate returns statistically different from the benchmark trading strategy, with both strategies generating very low or negative returns. For the momentum to outperform the benchmark strategy, predictability should be three times larger than observed from real data, but would entail substantial downside risk. In sum, the empirical evidence indicates that returns from STSM-type strategies are illusive for the commodities and period studied. Our results strongly suggest that inclusion of unrealisable roll yield generates the illusion of profitable STSM trading strategies in previous research.  相似文献

Recent research shows the existence of a selective corporate social responsibility (CSR) disclosure strategy that creates a gap between CSR disclosure and actual performance. These CSR decoupling practices compromise the credibility of CSR reports and have triggered a demand for the adoption of credibility enhancement mechanisms, such as adherence to the global reporting initiative (GRI) reporting guidelines, and the external assurance of CSR reports. The effectiveness of such mechanisms is not clear, however. This paper draws on legitimacy theory and addresses the issue of symbolic versus substantive use of assurance, and compliance with GRI reporting standards, by analysing their effect on CSR decoupling using an international sample of 1,939 companies (15,219 observations from 2002 to 2017). Analysis of a sub-sample of 708 firms (3,730 observations from 2011 to 2017) also shows that the application of GRI guidelines and the specific characteristics of the assurance provider—accountant, experience and specialisation—reduce CSR decoupling practices. The results provide researchers, managers, assurance providers, investors, stakeholders and regulators with additional insight into the value of the external assurance of sustainability reports and have important managerial and policy implications.  相似文献
