The authors provide new evidence on this hypothesis using a quasi-natural experiment, in which gambling regulators removed slot machines from some, but not all, neighborhood bars. The authors find that the removal of slot machines reduced personal bankruptcies of close neighbors (within 100 meters) but not neighbors slightly farther away. This is consistent with the removal of neighborhood slots serving as an effective spatial commitment device, which reduced close neighbors' temptation to gamble, thus allowing them to avoid bankruptcy.
