The paper's headline finding is one average market elasticity per year (2010 and 2011), stated in the results and repeated in the conclusion; the two coded rows are exactly these yearly grand means (-0.10 for 2010, -0.053 for 2011, within the stated 0.05-0.12 and 0.02-0.08 ranges), with no alternative specification preferred. || "Firstly, there exist a well defined and statistically robust values for the demand elasticity which can be estimated on average around (in absolute value) 0.05-0.12 in 2010 and 0.02-0.08 in 2011."
