S. Knack et P. Keefer, DOES SOCIAL CAPITAL HAVE AN ECONOMIC PAYOFF - A CROSS-COUNTRY INVESTIGATION, The Quarterly journal of economics, 112(4), 1997, pp. 1251-1288
This paper presents evidence that ''social capital'' matters for measu
rable economic performance, using indicators of trust and civic norms
from the World Values Surveys for a sample of 29 market economies. Mem
berships in formal groups-Putnam's measure of social capital-is not as
sociated with trust or with improved economic performance. We find tru
st and civic norms are stronger in nations with higher and more equal
incomes, with institutions that restrain predatory actions of chief ex
ecutives, and with better-educated and ethnically homogeneous populati
ons.
