Saving for a stormy day? The Jamaican Government Savings Bank and the precautionary savings motive

The Government Savings Bank of Jamaica (GSB) was created post-emancipation in order to serve the poor as a vehicle for precautionary savings and has been viewed as largely successful in this goal, at least after its restructuring in the late 1860s. We investigate this by examining GSB depositor behaviour after income shocks due to hurricanes. To this end, we combine digitized parish-level GSB account information with a hurricane damage index generated from historical storm tracks. Our results show little evidence of a precautionary savings motive by GSB account holders in that while net account balances and deposits drop after hurricanes, withdrawals and the number of accounts closed also fall. Additionally, the net decrease in account holders seems not to be driven by small savers, who are likely to be the poorest. Our findings are thus more in line with the GSB potentially being used to finance non-necessary consumption.
