Winning Paper

Does ESG reputational risk affect the efficiency and speed of adjustment of corporate investment?

by Ioannis Chasiotis, Dimitrios Gounopoulos, Dimitrios Konstantios,  Vasilios‐Christos Naoum,  Victoria Patsika

The winning paper, which is published in European Financial Management, explores the relationship between environmental, social, and governance (ESG) reputational risk and investment efficiency. The authors provide evidence that ESG reputational risk relates to higher corporate suboptimal investment (underinvestment) and a lower speed of adjustment back to the optimal investment level. Their findings hold for parametric and non‐parametric estimations of underinvestment and are robust to several techniques that address endogeneity and self‐selection. Overall, the study highlights the important role of ESG reputational risk in determining corporate investment efficiency.

Enhancement in a Firm's Information Environment via Options Trading and the Efficiency of Corporate Investment

by S. Anagnostopolou, CFA, L. Trigeorgis and A. Tsekrekos

The winning paper, which is published in the Journal of Banking and Finance, examines the association between enhancement in a firm’s information environment via options trading and firm investment efficiency.  Investment inefficiency is partly driven by information asymmetries between firm managers and capital providers, aggravating moral hazard concerns. The authors test whether enhancement in a firm’s information environment through higher volumes of options trading (including a natural experiment involving exogenous shocks via the Penny Pilot Program) is positively related to more efficient firm investment decisions. Their results confirm that enhanced informational efficiency via higher volumes of options trading is positively related to improvements in firm-level investment efficiency. Their findings are in line with the enhancement in the information environment stemming from options trading reducing agency and moral hazard concerns (an agency channel) and are not driven by alternative explanations such as managerial learning from informed traders or the lower cost of capital. Overall, the authors' findings suggest that an enhanced information environment via more options trading benefits firms’ investment decisions.
