This study investigates the relationship between family network density and income
hiding in rural Liberia. We link people’s behaviour in a modified lottery experiment
and a time preference game to detailed information about their family networks.
We find that individuals with a dense family network are more likely to pay a fraction
of their endowment to hide their earnings from the experiment. This association is
mainly driven by male respondents. We also find that men with dense family networks
have lower discount rates than those with smaller networks. Qualitative
responses suggest that these men perceive us as an alternative bank: if they have
no immediate purpose for the money, they prefer the research team to keep it for
two weeks. This prevents them from spending it on things other than its intended
use and may keep predatory members of the family network at bay. The negative
association between family network density and investment decisions is stronger if
these networks are characterised by members who sought financial support in the
past. Taken together, our results offer tentative evidence that dense family networks, under some conditions, have adverse impacts on economic decision-making.
