Recent developments in cognitive psychology and behavioral economics may explain the lower-than-predicted asset decumulation behavior posited by traditional life-cycle models during retirement, dubbed the retirement consumption puzzle. This study examines if mental accounting could be used to explain the retirement consumption puzzle. Utilizing panel data collected from the 1992–2018 Health and Retirement Studies, retiree age and age squared are examined using fractional polynomials and fixed effects regressions for their associations with varying categorical retiree asset decumulation patterns, including retiree wealth, nonhousing wealth, stocks, retirement accounts, bonds, liquid assets, vehicles, primary residence, and home equity. The results suggest that varying asset decumulation behaviors exist among retirees, which could be explained by retirees’ discretionary spending propensities. The discussion highlights the importance of understanding retiree behavioral spending constraints to allow for smooth consumption paths.
