Abstract headline pair is the Table 2 reduced-form biannual elasticity that grows from -0.09 (six months) to -0.27 (two years); authors state the biannual reduced-form is their primary specification || 'we estimate that the price elasticity of demand grows from -0.09 in the first six months to -0.27 two years later' (p.86); 'Due to their greater precision, we consider the biannual estimates our primary specification' (p.102-103)
