Subjective mortality beliefs contribute to contradictory savings rate puzzles at opposite ends of the life-cycle – the young under-save and retirees dis-save too slowly. We calibrate a canonical life-cycle model to new data from a large survey on subjective survival beliefs. Relative to a benchmark calibration using actuarial transition probabilities, the young under-save by 30%, and retirees draw down their assets 15% more slowly. The data supports the model’s predictions: Distorted mortality beliefs correlate with savings behavior, even controlling for risk preferences, and cognitive and socioeconomic factors. The salience of causes-of-death is a pivotal source of mortality belief distortions over the life-cycle.
