Pension contributions as a commitment device: Evidence of sophistication among time-inconsistent households

Sophisticated agents who are aware of their self-control problems value commitment devices that constrain future choices. Using Australian household data I test whether these households value commitment devices in the form of illiquid pension contributions. Estimating probabilistic choice models, the results confirm the conjecture that households with problems of self-control are more likely to invest in illiquid pensions while less likely to hold very liquid forms of assets.
