Conclusions state the two headline long-run own-price elasticities: high-income OECD DCCE (Reg II) = -0.22 and middle-income MG = -0.08 || 'The price elasticities for both groups in our estimates were significant but relatively small in magnitude. The middle-income group had a long-run response of -0.08 that was smaller than the OECD long-run response of -0.22.' (p.24); abstract: 'smaller for prices (-0.08 relative to -0.2)' (p.1); text prefers DCCE for high-income (Reg II) and MG for middle-income (Reg IV) (p.16-17)
