Board ancestral diversity and voluntary greenhouse gas emission disclosure

HFRC Working Paper Series | Version 01/2022
Prior research suggests that the disclosure of greenhouse gas (GHG) emissions—a primary cause of climate change—affects firm valuation. In this paper, we provide new insights into the determinants of the voluntary disclosure of GHG emissions. We show that board ancestral diversity has a positive and statistically significant effect on a firm’s scope and quality of voluntary GHG emission disclosure. This effect is robust to controlling for several other dimensions of board diversity as well as to addressing endogeneity and sample selection. Additional analysis suggests that board ancestral diversity has a higher impact on GHG emission disclosure in firms with low institutional ownership and high corporate complexity. We interpret these findings as consistent with the view that board diversity enhances monitoring and advising.

Transportation Research Part E: Logistics and Transportation Review | 11/2014
Based on practices and legislation in the shipping industry, we construct a corporate social responsibility (CSR) disclosure index for listed shipping companies. We use Markov Chain Monte Carlo (MCMC) techniques for Bayesian inference, and we estimate the marginal effects of firm characteristics on CSR disclosure for each firm. Our results show a positive relationship between CSR disclosure and financial performance for each firm in our international sample. Firm size, financial leverage, and ownership structure are also associated with CSR disclosure. Our findings suggest that a majority of listed shipping companies have integrated CSR practices into their strategic planning and operations.
