The Surprising Bias of PPML Estimates of Structural Gravity Models With Two‐Way Fixed Effects
Review of International Economics, EarlyView.ABSTRACT The previous literature has shown that the Poisson Pseudo‐Maximum Likelihood (PPML) estimator provides consistent and asymptotically unbiased estimates of the parameters of structural gravity models with two‐way fixed effects, although their standard errors need correction.

Defining the geographical level of competition: a taxonomy of industry tradability
Economica, Volume 93, Issue 371, Page 962-991, July 2026.Abstract The paper develops a taxonomy of industry tradability to define the geographical level at which competition takes place. First, it creates a novel dataset that combines production and international trade data for both goods and services industries, defined at a detailed (3‐digit) level of industry aggregation for 15 European countries.
