“…Whether PTAs with deep provisions may be more effective in boosting trade, including value‐added trade, has more recently received some scholarly attention. Research in this stream (e.g., Osnago, Rocha, & Ruta, 2017; Ornelas, Turner, & Bickwit, 2018) highlights in particular the importance of deeper forms of integration for addressing cross‐border policy spillovers and time‐inconsistency problems arising from the fragmentation of production across national borders, finding that PTAs with more rigorous provisions regarding the rules of origin (RoOs) or behind‐the‐border issues are more likely to facilitate the expansion of trade flows (Dür, Baccini, & Elsig, 2014; Estevadeordal & Suominen, 2005; Orefice & Rocha, 2014; World Trade Report, 2011) or lead to increases in both bilateral parts and components trade and re‐exported value added (Laget, Osnago, Rocha, & Ruta, 2018).…”
