The study investigates the role of post-disaster credit market access in determining micro-flood-insurance demand in the rural floodplains of Bangladesh. In a large-scale household survey we asked 3,000 residents in six different districts of Bangladesh about their willingness to participate and pay for a hypothetical flood-insurance programme. Combining factors put forward in risk theory and economics, we employed the ‘triple-hurdle’ approach to model the three stage sequential decision problem. Our results show that post-disaster microcredit has a positive relationship with insurance participation decision and a negative relationship with willingness to pay premium for flood-insurance. One possible explanation for these findings is that, on average and other things remaining the same, households who accessed post-disaster microcredit to cope with natural disaster induced losses in the past were willing to invest in flood-insurance as an alternative disaster coping measure so long as they considered the proposed insurance premium cheaper than the cost of accessing post-disaster microcredit.
