Which ethics will make us individually and socially happier? A cross-culture and cross- development analytical model

This paper provides an analytical model representing four polar ethical approaches, by linking them to the main ethics suggested by the philosophical, psychological, and socio-economic literature. Moreover, it develops the analytical model in order to obtain rankings of the 4 polar ethical approaches in terms of happiness and, consequently, to provide insights on which ethical approach should be adopted by each individual, according to his characteristics (income level, in DCs or in LDCs, aspiration level): some dynamics are predicted, if the Golden and the Copper rules are applied. Finally, this paper provides insights on which ethical approach should be adopted by each society, according to its characteristics (DCs or LDCs, social distribution of aspiration levels), by predicting happiness levels in alternative countries, according to the prevailing ethics, and by comparing these predictions with the observed happiness levels, in order to provide an empirical test of the analytical model: some dynamics are predicted, with non-Protestant DCs moving to higher, and Protestant DCs towards lower, happiness levels (conditioned to the per capita income), due to the increasing and decreasing rejection of the Golden and Copper rules, respectively, and with LDCs moving to lower (conditioned to the increasing per capita income) in the short-run and higher happiness levels in the long run, by establishing and entertaining conditions that set clear incentives for moral behaviour, in order to increase and decrease the adoption of the Golden and Copper rules, respectively.
