While it is recognized that decision making requires effort, less attention has been paid to how the effort of making decisions influences decision outcomes. A relatively new construct, decision fatigue (i.e., “the impaired ability to make decisions and control behavior” [Pignatiello, Martin, and Hickman 2020]), describes the weariness that comes from repeated decision making. Using data from a longitudinal panel study of financial decision making with 3,042 Australian adults (ages 18+) conducted in 2021, we examine the antecedents and consequences of decision fatigue for consumer financial decisions. For the antecedents, we examine the roles of demographics, financial literacy, and objective financial situation in the individual’s self-reported decision fatigue. For the consequences, we examine the association between decision fatigue and overall well-being directly and indirectly through financial well-being.
