“…To perform this test, we first carry out a probit regression model, as shown in equation (2), to estimate the likelihood that firms issue CSR reports and receive CSR performance scores, to obtain the Inverse Mills Ratio (known as Lambda ), the self‐selection parameter, and in the second‐stage regression, we insert Lambda in the model specification as shown in equation (3): where CSRD is an indicator variable set to 1 if a firm issues a CSR report and receives a CSR rating in a given year, and 0 otherwise. Mandatory is used to measure the probability of whether a sample can be observed, and is defined as a dummy variable equal to 1 if a firm is mandated to disclose a CSR report in a given year, and 0 otherwise (Chen, Hung, & Wang, 2018; Kong et al., 2020). According to prior research, Mandatory affects firm‐level CSR but has no direct impact on the presence of QFIIs.…”
