“…Three recent studies find no effect of treaties on FDI(Baker, 2014;Daniels, O'Brien, and von der Ruhr, 2015; Beer and Loeprick, 2018); three find a positive effect(Marques and Pinho, 2014; Van 't Riet and Lejour, 2017;Hong 2018).2 Under a PPT, broadly speaking, treaty benefit is denied if one of the main purposes of an arrangement is to obtain those benefits; an LOB seeks to limit tax treaty benefits to genuine residents of the other contracting state.3 Advanced economies seem to opt for the (more complex to enforce) PPT, rather than the LOB, far more often than emerging economies.©International Monetary Fund.
