In this paper, we use an accurate panel of individual spending, income, and financial account balances to learn more about expenditure and household financial structure changes around retirement. The longitudinal nature of our data allows us to estimate individual fixed-effects regressions and thereby control for all selection on time-invariant (un)observables. Upon retirement, individuals spend less on ready-made food, fuel, and clothes and more in pharmacies, which is consistent with reductions in work-related expenses. However, individuals also spend less on other consumption categories, such as sports and activities and fine dining. Furthermore, we are in a unique position to document the effect of retirement on credit-card, checking, and savings account balances: we find that individuals deliver by reducing consumer debt and increasing liquid savings. These findings cannot be rationalized via work-related expenses. Any rational agent would save before retirement, the expected fall in income, and dissave after retirement rather than the exact opposite.
