The negative linkage between income inequality and social trust is widely acknowledged. Despite this consensus, it remains unclear at what level of aggregation income inequality matters most to the cultivation of social trust. In a comprehensive review, Wilkinson and Pickett (Annu Rev Sociol 35:493–511, 2009) speculate that income inequality is most important when measured at the societal level, whereas for lower units of aggregation economic development becomes a stronger predictor. Merging regional inequality data for 216 regions in 22 European countries (2010–2014) to the European Social Survey, this paper is the first to examine this claim for social trust. The results demonstrate that in non-Eastern European countries most of the variation in social trust is accounted for by differences in inequality between countries rather than differences in inequality within countries. For economic development, the opposite is true. Within-country differences in economic development relate significantly to social trust, while between-country differences do not. I conclude that social trust is more strongly affected by the stratification of society as a whole than by income inequalities within smaller units of aggregation.
The economic discipline plays a performative role in constructing the moral order of market society. Yet, little attention has been paid to what economists explicitly regard as moral or how they conceive of morality. This article reflects a recent attempt to put morals into economics, that is, to introduce morality as a research topic in behavioural and experimental economics. It maps three research programs that theorize the moral economy. The programs emphasize the moral foundations of market society, the moral limits of market expansion, and the moral consequences of market trading and, thus, appear irreconcilable with classifications of economists as market enthusiasts or moral agnostics. At the same time, however, the literature centres on an “economized” form of morality that is corrective to market inefficiencies, attributed to the responsibility of the individual, and expressed in rational terms. In doing so, this literature contributes to redefining moral problems in economic terms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
