Trust and macroeconomic performance: A two-step approach

We reexamine the role of trust in macroeconomic performance using a new econometric method, a two-step approach adopted by. Di Tella et al (AER, 2001). In the first step, the measure of trust is constructed from the micro-regression of trust. This method allows us to extract the component of trust that is not influenced by individual-level socio-economic factors. In the second step, measures of macroeconomic performances are regressed on this improved measure of country-level trust. We find a strong positive relationship between the level of trust and real GDP per person stipulated by an increase in investment. Our results also indicate that the impact of trust on macroeconomic variables estimated by previous studies is biased upwards.
