Using credit ratings as an uncertainty-reducing mechanism, we provide evidence of the beneficial impact of multiple credit ratings on reducing IPO underpricing and filing price revision. We find that the acquisition of multiple ratings in the pre-IPO period mitigates uncertainty more than the acquisition of a single rating. Multi-rated firms also have higher probabilities of survival than those with a single rating, whereas credit rating levels matter only for IPOs with more than one rating. The IPOs that are awarded the first rating on the borderline between investment and non-investment grades are more likely to seek an additional rating.

This paper examines the effect of board gender diversity on renewable energy consumption. Using a panel of 11,677 firm-year observations from the USA for 2008–2016, we find a positive relationship between board gender diversity and renewable energy consumption. Moreover, boards require two or more women for women to have a significant impact on renewable energy consumption, consistent with the critical mass theory. Further, we document that the positive impact of female directors on renewable energy consumption stems from female independent rather than female executive directors. Finally, we find a positive effect of the interaction between renewable energy consumption and board gender diversity on firm financial performance. Our findings are robust to different identification strategies and estimation techniques.
