We extend the simulation results given in Santos-Silva and Tenreyro (2006, 'The Log ofGravity', The Review of Economics and Statistics, 88, pp.641-658) by considering datagenerated as a finite mixture of gamma variates. Data generated in this way can naturallyhave a large proportion of zeros and is fully compatible with constant elasticity models suchas the gravity equation. Our results confirm that the Poisson pseudo maximum likelihoodestimator is generally well behaved.
