Why do levels of corporate social performance (CSP) differ so much across countries? We answer this question in an examination of CSP ratings of more than 2600 companies from 36 countries. We find that firm characteristics explain very little of the variations in CSP ratings. In contrast, variations in country factors such as stages of economic development, culture, and institutions account for a significant proportion of variations in CSP ratings across countries. In particular, we find that CSP ratings are high in countries with high income-per-capita, strong civil liberties and political rights, and cultures oriented toward harmony and autonomy. Furthermore, we find that home country factors explain a smaller portion of the overall variations in CSP for multinationals and cross-listed firms than for non-multinationals and pure domestic firms, respectively.

We examine merger and acquisition (M&A) transactions in which the acquirer and the target share a common auditor. We predict that a common auditor can help merging firms reduce uncertainty throughout the acquisition process, which allows managers to more efficiently allocate their capital, resulting in higher quality M&As. Consistent with our prediction, we find that deals with common auditors have higher acquisition announcement returns than do non-common-auditor deals. Further, we find that the common-auditor effect is more pronounced for deals with greater pre-acquisition uncertainty and deals involving acquirers and targets that are audited by the same local office of the common auditor. We also find that there is an increased probability of an M&A for firms with a common auditor. Collectively, our evidence suggests that common auditors act as information intermediaries for merging firms, resulting in higher quality acquisitions.
