In this chapter, I review the state of the small literature that developed around this issue, as of April 2006. This chapter is structured as follows. Section 2 reviews the author’s contribution, Sections 3–5 raise key criticisms of the author’s work: excessive pooling; fixed effects and variation across countries and time; and selection bias. Sections 6–8 issue various challenges to the critics: beyond bilateral trade flows; beyond trade flows; and what does the WTO do? Section 9 concludes. 2 WHAT I DID My initial (2004a) entrée used bilateral data to estimate the effect of membership in the GATT/WTO on trade. Since this paper has generated the most heat, it is worth explaining my methodology a little. I used a standard ‘gravity’ model of bilateral trade augmented with additional controls: ln (Tijt) 5 bD ln...
