To provide a quantitative assessment of these results, using Table 4 column 7, a one-unit increase in the SIGI (as explained above, representing a country's social transformative change required to move from a situation with perfectly discriminatory social institutions to a situation of perfect parity) would induce an increase of 0.157 on average at the individual level in the ladder of life satisfaction (0-10 scale). This is quite large when comparing with the effect of life events such as getting married or becoming widowed that are known to be important determinants of life satisfaction. For instance, Lucas et al. ( We now use the SIGI's coefficients from Model 1 first to quantify the loss in subjective well-being associated with the current level of gender-based discrimination in social institutions and second to estimate the gains, in terms of increased level of life satisfaction that could be achieved with greater gender parity. Simulations are carried out using equation 2 and relying on individual-level variations in life satisfaction.
