Do Tax Deferred Accounts Improve Lifecycle Savings? Experimental Evidence

Abstract In an individual decision-making experiment, we investigate the impact of Tax Deferred Accounts (TDAs). We design six treatments to study various channels through which TDAs may affect decisions. Across both student and Mturk samples, we consistently find that TDAs significantly increase retirement wealth compared to environments with only one non-tax advantaged, liquid saving account. This increase is primarily explained by the requirement of making retirement savings decisions precede consumption decisions. Educating participants by providing a tax calculator has minimal effects. Our results highlight the effectiveness of TDAs in enhancing retirement preparedness and the significance of the order of consumption/savings decisions.
