Abstract
This study investigates through explainable AI the impact of financial and non-financial factors on a firm's ex-ante cost of capital, which is the reflection of investors' perception of a firm's riskiness. We apply the XGBoost algorithm and the Shapley value approach to a sample of more than 1,400 listed companies worldwide. Results indicate the most relevant financial and non-financial indicators are: firm size, ROE, firm portfolio risk, and regulatory quality. These factors influence firm's ex-ante cost of equity by changing its investors' risk perception. We also suggest the relevance of ESG factors in predicting the cost of capital.
