“…These studies focus on reasons for supply chain actors to adopt quality standards (Stranieri et al , 2017), their preferred enforcement mechanisms (van der Merwe et al , 2019), quality performance (López-Bayón et al , 2018) and quality control (Jraisat and Sawalha, 2013). A specific field of studies analyzes how quality standards affect bilateral contract arrangements between supply chain actors (Raynaud et al , 2005; Banterle and Stranieri, 2008; Wever et al , 2010; Ghozzi et al , 2016, 2018; Fernández-Barcala et al , 2017).
