Authors rely on the fixed-effects overall estimate and headline it as the study's own-price elasticity; Hausman rejects RE so FE preferred || 'The estimated own-price elasticity [-1.356] is relatively large' (p.7); 'these estimations do not withstand the Hausman test. Therefore, the study depends on the fixed-effect model (FE) estimations' (p.8-9)
