Why CEOs invest in Corporate Social Responsibility initiatives: evidence on Shariah compliant firms
No full textThe aim of this article is to investigate the motivation of CEOs to invest in Corporate Social Responsibility (CSR) activities. To carry out this analysis, we assess a sample of US conventional and Shariah Compliant (SC) firms, from Dow Jones Indices. As SC firms undergo business and financial screening, they are expected to follow different managerial styles and capital structures as compared to conventional firms. This comparison is important in view of the growing size of the Islamic Financial Services Industry that has surpassed total asset values of USD 2.00 Trillion. Existing literature argues that, for conventional firms, CEOs spend on CSR either to promote their private benefits (agency view) or to reduce conflicts among shareholders (conflict resolution view). Our results provide evidence that across both types of firms, CEOs do not invest in CSR initiatives to pursue selfish motives but to resolve conflicts among stakeholders to maximize firm value. The findings are also robust across different specifications and methods in order to address endogeneity issues. This article contributes to the growing literature on managerial styles, capital structure and Islamic Finance, carrying out important implications for the investment industry and for the long-term value of the firm
Modelling systemic risk of energy and non-energy commodity markets during the COVID-19 pandemic
No full textCOVID-19 led restrictions make it imperative to study how pandemic affects the systemic risk profile of global commodities network. Therefore, we investigate the systemic risk profile of global commodities network as represented by energy and nonenergy commodity markets (precious metals, industrial metals, and agriculture) in pre- and post-crisis period. We use neural network quantile regression approach of Keilbar and Wang (Empir Econ 62:1–26, 2021) using daily data for the period 01 January 2018–27 October 2021. The findings suggest that at the onset of COVID-19, the two firm-specific risk measures namely value at risk and conditional value of risk explode pointing to increasing systemic risk in COVID-19 period. The risk spillover network analysis reveals moderate to high lower tail connectedness of commodities within each sector and low tail connectedness of energy commodities with the other sectors for both pre- and post-COVID-19 periods. The Systemic Network Risk Index reveals an abrupt increase in systemic risk at the start of pandemic, followed by gradual stabilization. We rank commodities in terms of systemic fragility index and observe that in post COVID-19 period, gold, silver, copper, and zinc are the most fragile commodities while wheat and sugar are the least fragile commodities. We use Systemic Hazard Index to rank commodities with respect to their risk contribution to global commodities network. During post COVID-19 period, the energy commodities (except natural gas) contribute most to the systemic risk. Our study has important implications for policymakers and the investment industry
Does the regional proximity lead to exchange rate spillover?
No full textTo understand whether regional proximity leads to exchange rate connectedness, we explore dynamic co-movement of currencies from two important regions namely the South Asian Association for Regional Cooperation and Association of Southeast Asian Nations by using Continuous Wavelet Transformation approach. Our results reveal very little co-movement between member currencies of both regions and imply that regional proximity does not necessarily translate into exchange rate connectedness. The results remain robust to alternate specifications. Our findings carry important implications for academia and policymakers
Dividend policy: The case of Shariah-compliant firms
No full textShariah-compliant firms (SCF) cannot use debt to mitigate agency problems, and in this scenario the dividend payout policy becomes a highly important tool of corporate governance for shariah-compliant investors. This chapter highlights the dividend payout behaviour of SCF by comparing them to conventional firms. We performed a detailed review of existing literature and also calculated descriptive statistics, using various specifications using a sample of representative SCF and market firms for United States (US) market from 2006-2015, in order to investigate if the dividend payout behaviour of SCF differs from the market. However, we did not find any notable difference. Our results also showed no difference in payout decisions at different levels of idiosyncratic risk. In summary, we observed that firms with good governance, large asset size, higher profitability, higher Retained Earnings/Total Earnings (RE/TE) and lower market-book ratio, lower idiosyncratic risk and lower financial constraints, on average, pay higher dividends. The results remain similar across both kinds of firms
Cryptocurrencies versus environmentally sustainable assets: Does a perfect hedge exist?
No full textIn the wake of proliferation of cryptocurrencies and growing concerns regarding their environmental impact, we investigate the dynamic co-movement of digital assets and environmentally sustainable assets. We use daily data of five global indices from 01 March 2017 to 15 May 2022. The results suggest that environmentally sustainable indices and cryptocurrency indices demonstrate co-movements during pandemic. However, in the normal times, they mostly remain detached from each other. Therefore, it can be argued that both the asset classes can serve as hedge against each other. The findings carry important implications for the investment industry and regulators.Other Information Published in: International Review of Economics & Finance License: http://creativecommons.org/licenses/by/4.0/See article on publisher's website: https://dx.doi.org/10.1016/j.iref.2023.02.005</p
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
