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.

Enhancing energy recovery from waste through torrefaction: A study on municipal solid waste (MSW) fractions under N2 and CO2 atmospheres

The Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1100-1120, March 2026.
An overview of municipal solid waste torrefaction under various sweep gases. Abstract This study investigates the impact of torrefaction on municipal solid waste (MSW) fractions, focusing on energy recovery, calorific value enhancement, mass yield reduction, and energy densification under both nitrogen (N2) and carbon dioxide (CO2) atmospheres.
