Investor-driven 'short-termism' is said to harm EU public firms' ability to invest for the long term, prompting calls for the EU to better insulate managers from shareholder pressure. But the evidence offered—rising levels of repurchases and dividends—is incomplete and misleading: it ignores large offsetting equity issuances that move capital from investors to EU firms. We show that, over the last 30 years and the last decade, net shareholder payouts have been moderate and investment and cash balances have increased. In sum, the data provide little basis for the view that short-termism in the EU warrants corporate governance reforms.  相似文献

Russian agriculture is coming off a successful period under Minister Alexander Tkachev. Despite his successes, new agricultural leaders were named in May 2018 to guide agriculture during Putin’s fourth term. The article analyses the condition of and prospects for the agricultural sector during 2018–2024, using a SWOT framework (strengths, weaknesses, opportunities and threats). The analysis examines four strengths, six weaknesses, four opportunities and three threats.  相似文献

This paper provides a bibliometric and Scientometric analysis of the corporate social responsibility (CSR) in banking sector. Our study analyzes 551 articles from the Scopus database to find out the relationship between CSR and banking. A bibliometric method was used to visualize the results using R-studio and VOS viewer software. The Scientometric analysis was conducted to determine the findings and mappings of the research themes, directions of current and future research, impact, co-occurrence, co-citations and impact and collaboration trends. We explore how CSR literature has evolved over the years in the banking sector between 1993 and 2021. We find that publication in the CSR and banking domain has increased significantly during 2017 and 2021. Social aspects, board of directors, CSR, environment, competitions, Islamic banking, sustainability, disclosure, ethics, legitimacy theory, sustainable banking, loyalty, and brand equity are the popular research trends and collaboration trends identified. We also provide further scope of the study based on the extensive review of the past literature. Our findings may provide help to future researchers, bankers, and regulators in understanding the current trends and future research progression in the CSR and banking sector.  相似文献

We examine the impact of innovation disclosure through patenting on firms' cost of debt, focusing on the American Inventors Protection Act (AIPA) as an exogenous shock in innovation disclosure regulation. Post‐AIPA, firms have an incentive to apply for patents only if commercial success is likely. Accordingly, we expect post‐AIPA patents to be a better proxy for successful innovation activity, and thus to have a stronger effect on reducing the cost of debt than pre‐AIPA patents. Indeed, we find that pre‐AIPA patents reduce the cost of debt only for the most innovative firms, while post‐AIPA, this effect holds for all firms.  相似文献

We examine risk profiles of the Portuguese stock market index component stocks using a novel approach to the classical capital asset pricing model (CAPM). Specifically, we estimate the CAPM via fractal regressions that allow studying the marginal effects at selected scales. In this way, we can reveal whether the risk is perceived differently by market participants with different investment horizons. Apart from the analysis itself, we provide new statistical insights into the issue of separating and comparing the scale-specific effects with statistical validity. We find several stocks deviating from an expected risk perception homogeneity across investment horizons. This is true for both analysed periods, i.e. before and after the global financial crisis. There are also several stocks that changed their relationship to the market portfolio in between, which has strong implications for possible portfolio construction. The proposed methodology is not limited to financial topics but can be used in any discipline where the scale-specific marginal effects might be of interest.  相似文献
