“…Jian and Wong (2010) and Cheung et al (2006) argue that rms can use normal business operation transactions, such as sales or purchases, to extract wealth from minority shareholders. Most of the prior tunnelling research is conducted using related party receivables or payables as the proxy (Bauer et al, 2020;Chan et al, 2016;Chen et al, 2014;Gao and Kling, 2008;Gong et al, 2021;Nurazi et al, 2015 andWulandari &Setiawan, 2021). However, there are other ways to measure tunnelling such as by using related party sales and purchases ( Gordon et al, 2004;Qu et al, 2020), abnormal management perks (Bauer et al, 2020), and asset acquisition, asset sales, and equity sales to related parties (Cheung et al, 2009a).…”
