To disclose or not to disclose: What determines a firm’s decision to voluntarily report carbon information? Aoife Brophy Haney Judge Business School, University of Cambridge IAEE International Conference, Stockholm, 21 June 2011.
Motivation • Problem: • Carbon reduction in large organisations • Potential solutions: • Information and reputation as regulation • Questions: • Non-financial incentives? • Voluntary vs. mandatory?
Information • Information problem • Lemons (Akerlof 1970) • Price vs. quality (Tirole 1988, Stiglitz 2000) • Information disclosure • Strategic behaviour(Jin 2005) • Herding and learning (Bikhchandani 1998)
Incentives to disclose • Costs of disclosure (-) • Consumers (+) • Investors (+) • Competition (?) (Grossman 1981; Jin 2005; Jovanovic 1982; Healy and Palepu 2001; Verrecchia 2001; Mathios 2000; Jin and Leslie 2003)
Environmental disclosure Determinants of voluntary disclosure/participation? • Size (+) • Environmental impact (+) • Consumers (+) • Competition? (Arora and Cason 1995, 1996; Khanna and Damon 1999; Khanna and Anton 2002)
Research Question • What determines a firm’s decision to voluntarily disclose (carbon) information? • In particular, how does competition affect the decision to disclose?
Hypotheses H1: Consumer-facing firms are more likely to disclose carbon information voluntarily H2: Firms in more competitive industries are less likely to disclose carbon information voluntarily H3: Firms that are more dependent on capital markets are more likely to disclose carbon information
