Measuring Subjective Well-being Capability: A Multi-Country Empirical Analysis in Europe

The main aim of this paper is to conceptualise and empirically estimate subjective well-being capability. The empirical demonstration of the conceptual framework is applied in a selection of European countries: Poland and its leading emigration destinations the United Kingdom, Germany, the Netherlands, Ireland, France and Italy. The paper advances the measure of subjective well-being capability (SWC) as the integration of the subjective well-being measure with the capability approach in a unified measurement framework. Following the development of a conceptual model, the theoretical framework is operationalized empirically to quantify measures of SWC across the selected countries using a Multiple Indicators and Multiple Causes Model. Data from the European Quality of Life Survey is employed. A comparative analysis compares the SWC measures across countries as well as comparing SWC with conventional well-being measures such as overall happiness and GDP per capita. The results of the study reveal a significant correlation between the SWC based on a general model for all countries, overall happiness, and GDP per capita. However, it also suggests that country-specific SWCs, calculated from tailored models, could substantially deviate from traditional well-being measurements. This attribute suggests that SWC could be a practical tool for assessing individual contexts, as reflected in the tailored models, even though it might not serve as the optimal instrument for country ranking (via the general MIMIC model).
