“…Guided by the theoretical model of Anderson et al (2019), 3 we specify two estimating gravity equationsone for trade and one for FDI, which are (i) consistent with and representative of a large number studies that quantify the impact of various determinants on FDI (e.g., Eicher et al, 2012;Blonigen and Piger, 2014;Kox and Rojas-Romagosa, 2020;Laget et al, 2021), and (ii) capitalize on the latest developments in the trade gravity literature (e.g., Head and Mayer, 2014;Yotov et al, 2016). Specically, we rely on the Poisson Pseudo-Maximum-Likelihood estimator to account for potential heteroskedasticity in the bilateral trade and FDI data and to take advantage of the information in the zero trade and FDI ows (cf.…”
