Coded cells are the CEM-OLS short-run own-price coefficients (Table B-1), which the authors present 'for comparative purposes'; the authors' genuinely preferred estimates are the VEMA-OLS long-run variable elasticities in Table 3/B-2, which are NOT among the coded cells. Marking the coded CEM-OLS SR own-price elasticities as the representative reported estimates. || 'the constant elasticity model (CEM) has been widely used in other econometric studies... Consequently, the OLS estimate of CEM is given for comparative purposes' (p.9); 'only the OLS and IV estimates of VEMA are given' and 'the OLS models are better' (p.8).
