Table 3.
Input parameters used to vary the base model for each income quintile, from lowest (1) to highest (5) (BMI distribution not shown)
| Quintile | 1 (lowest) | 2 | 3 | 4 | 5 (highest) |
| Elasticities | |||||
| Own-price elasticity (SD) | −1.33 (0.10) | −1.34 (0.50) | −1.13 (0.40) | −1.20 (0.70) | −1.20 (0.09) |
| Cross-price elasticity diet drink (SD) | −0.08 (0.03) | −0.1 (0.04) | −0.16 (0.41) | −0.24 (0.07) | −0.31 (0.12) |
| Cross-price elasticity milk (SD) | 0.05 (0.03) | 0.05 (0.30) | 0.03 (0.03) | 0.004 (0.02) | −0.01 (0.09) |
| Cross-price elasticity juice (SD) | 0.12 (0.09) | 0.14 (0.19) | 0.17 (0.18) | 0.20 (0.15) | 0.24 (0.17) |
| Expenditure relative to mean | |||||
| Sugar-sweetened beverages and diet drinks (SD) | 0.11 (0.44) | 0.28 (0.80) | 0.56 (1.42) | 1.03 (2.32) | 3.02 (6.86) |
| Milk (SD) | 0.22 (0.55) | 0.50 (1.06) | 0.81 (1.56) | 1.29 (2.43) | 2.18 (4.26) |
| Juice | 1 | 1 | 1 | 1 | 1 |
| Relative mortality (SE, unchanged for quintiles) | |||||
| Mortality men | 1.17 (0.11) | 1.13 | 1.04 | 0.96 | 0.87 |
| Mortality women | 0.96 (0.09) | 0.97 | 0.99 | 1.01 | 1.03 |
Expenditure relative to mean and relative mortality are used to scale the underlying input rates for each age and sex group. Price elasticities are used directly.
