“…These factors include the preference erosion[14] that stems from both the greater liberalization [15] of most favoured nations (MFN) tariffs (in particular since the creation of the WTO) and the end of multi-bre agreement (e.g., Inama, 2003;Klasen et al, 2021;Low et al, 2009;Persson, 2015b); domestic economic policies, including trade policies [16] and the real exchange rate policies [17]; the limited supply response capacity of bene ciary countries (e.g., Gradeva and Martínez-Zarzoso 2016;Low et al, 2009;Prowse, 2010;Yannopoulos, 1986Yannopoulos, , 1987; the inadequate product coverage (e.g., Low et al, 2009;Persson, 2015b); the existence of restrictive rules of origin as well as other compliance costs by the bene ciary countries when claiming a NRTP (e.g., Brenton and Özden 2009;Gitli, 1995;Persson, 2015b;WTO, 2019); and the lack of certainty or stability of the improved market access brought about by the NRTP (e.g., Hakobyan, 2020;Persson, 2015b). For example, concerning the rules of origin, the literature has shown that restrictive 'preferential' rules of origin can constrain the bene ts of tariff preference margins (e.g., Cadot et al, 2014) by leading to a misallocation of resources (e.g., Falvey and Reed, 1998;Mattoo et al, 2003) and ultimately undermining the utilization of NRTPs (Hakobyan, 2015;Herz and Wagner, 2011;Inama, 2003;Sytsma, 2021;WTO, 2019). WTO (2019) has explored the rationale for the low rates of preference utilization for several agricultural exports under many NRTPs, despite the simple feature of agricultural products, and the fact that these products are subject to simple rules of origin.…”
