B.1 The Partial Equilibrium Example without Sequentiality In this Appendix, we revisit our partial equilibrium example with four countries and four stages in section 2.4, but we consider an alternative scenario without sequentiality. More specifically, we still consider a symmetric Cobb-Douglas technology with four ‘stages’contributing to value added, but we assume that these four stages occur simultaneously and are combined into a non-tradeable final good. We continue to focus on serving consumers in country D, so this boils down to a “spider” sourcing model in which assemblers in D choose the optimal source for each of the required four inputs. The rest of the specifics of the exercise are as in section 2.4: for each level of trade costs considered, we run one million simulations with production costs aj cj being drawn independently for each stage n and each country j from a lognormal distribution with mean 0 and variance 1.
