Authors' headline implied own-price elasticities from expected-marginal-price IV specification: low/mid/high tariff-knowledge groups = -0.24/-0.28/-0.33; base preferred elasticity around -0.28 (exp. marginal) / -0.39 (IV). Abstract stresses heterogeneity rather than a single point estimate. || 'Using expected marginal price, the implied price elasticity for the low group is -0.24, compared to price elasticities of -0.28 and -0.33 for the middle and high groups.'
