“…With the general implementation of the policy, an increasing number of studies use objective data to conduct empirical research. The sample covers several countries, including the United Kingdom (Gambetta et al, 2019; Pinto & Morais, 2019; Sierra‐García et al, 2019), Thailand (Kitiwong & Sarapaivanich, 2020; Suttipun, 2021) and New Zealand (Li et al, 2019a). The research includes the determinants of the quantity and content of KAMs (Pinto & Morais, 2019; Sierra‐García et al, 2019), as well as the relationship between KAMs and audit quality (Suttipun, 2021), audit fees (Li et al, 2019a), follow‐up financial restatements and other factors (Kitiwong & Sarapaivanich, 2020).…”
