Abstract frames headline finding as predominant average-price responsiveness recovered via the reduced-form IV/bunching methods; the full-controls IV specification (Table 3 cols 4-6) is the paper's final reduced-form elasticity, with the ~ -0.13 to -0.16 marginal/average estimates the values the demand literature would cite. || 'While small in number, the exaggerated responses by these households have a large effect in aggregate, masking an otherwise predominant response to average price' (p.433, abstract); 'The estimated elasticity is slightly higher at -0.155' (p.450)
