Abstract: The cross-country correlation between social trust and income equality is well
Terms of use:
Documents in EconStor maydocumented, but few studies examine the direction of causality. We show theoretically that by facilitating cooperation, trust may increase efficiency and lead to more equal outcomes, while the feedback from inequality to trust is ambiguous. Using a structural equations model estimated on a large country sample, we find that trust has a positive effect on both market and net income equality. Larger welfare states lead to higher net equality but neither net income equality nor welfare state size seems to have a causal effect on trust. We conclude that while trust facilitates welfare state policies that may reduce net inequality, this decrease in inequality does not increase trust. (2004) and also Kumlin and Rothstein (2005). On the other hand, if the crosscountry correlation between income equality and social trust is driven only by the fact that deeply rooted trust levels explain both trust today and the degree of welfare state redistribution, there is no feed-back dynamic from redistributive welfare state policies to trust.
KeywordsThe possible causal relations are illustrated in Figure 1, where full arrows show causal relations argued for in previous literature. This paper investigates the causality between trust and equality, and the potential role of welfare state policies as mediators of the causal associations.We do so by exploring two central questions, not dealt with before. First, do welfare states have an independent effect on income equality, or is the correlation between welfare state size and income equality spurious, in the sense that trust explains both welfare state size and income equality? Second, if welfare states do increase equality of income, does this further increase trust, suggesting a positive feedback dynamics?Figure 1: The correlations between welfare state size, social trust and income equality.Departing from a standard cooperation game, we show that the overall type of cooperation facilitated by trust and trustworthiness will under plausible circumstances increase equality. We then estimate structural equations models that account for potential feedback effects between income equality and social trust. The results document a two-way causal relation between market (pre-redistribution) income inequality and social trust, but no feedback from net inequality to trust. Furthermore, the effect from trust t...
