This study examines the relationship between the adoption of blockchain technology and environmental efficiency by using a sample of US firms over the 2015-2019 period. Our results indicate that the adoption of blockchain technology is positively and significantly associated with environmental efficiency, suggesting that blockchain improves environmental sustainability. In further analyses, we determine that the relationship between blockchain and environmental efficiency is more pronounced for firms in financial and technological industries than for those in other industries.Our findings are also robust to other methods that control for endogeneity, including difference in difference regressions and propensity score matching. Overall, we provide empirical evidence to incentivize business leaders and policymakers to adopt innovative technologies, such as blockchain.
We examine the impact of three business strategies separately and in combination on the tendency for firms to engage in corruption. Using a sample of 56,827 firm-year observations for small-and medium-sized enterprises (SMEs) over the 2006-2018 period, we find that firms with business group affiliations are more likely to engage in corrupt practices in countries with low business freedom. However, those in countries with high business freedom are less likely to do so. We also find that firms that engage the services of external auditors and adopt international standards are less likely to be corrupt, especially in countries with weak financial reporting standards. Our results also show that corruption intensity reduces even more for firms that employ the three strategies, whether we consider institutional factors or not. This result holds when we use a three-way interaction term. We conclude that the three strategies are mutually reinforcing and that firm-level and country-level efforts complement each other in mitigating corruption.
The conclusions of any quantitative research must be supported by appropriate data. This chapter discusses the methods of collecting quantitative data for research. It begins by giving an overview of the nature of quantitative research. It also discusses the two major sources of collecting quantitative data. For primary data collection, issues such as sampling, measurement and surveys are discussed. Examples and sources of obtaining secondary data are also presented. Finally, some ideas are provided for how to evaluate quantitative data in order to ensure it is appropriate for analysis.
We investigate the informativeness of earnings announcements in African stock markets and examine whether, conditional on the level of synchronicity and liquidity of stocks, market reactions are influenced by earnings characteristics. Normalized volatility indicates that earnings announcements are informative across the sample. The results are driven by less frequently traded stocks and informativeness manifests more clearly at announcement and in the post‐announcement window. There is little evidence of leakage. Informativeness is also present for highly traded stocks, notably after announcement. Cross‐sectional tests provide evidence of an effect of both earnings fundamentals and investor behaviour on stock returns around earnings announcements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
