Spending predictions
Past research on spending Spending behavior
e.g., Furnham, 1999; Kidwell et al., 2003; Lee & Ariely, 2006; Vohs & Faber, 2007
Corporate forecastse.g., Flyvberg et al., 2009; Schwartz & Cohen, 1995
Past research on predictions Predictions are often optimistically biased
e.g., Armor & Taylor, 1998; Dunning, 2007
Time spent on projects is underestimated →”planning fallacy” e.g., Buehler et al., 1994, 2002; Kahneman & Tversky, 1979

Goals and Predictions
Two theories of goals affecting predictions Motivated reasoning (Kunda, 1990) Desirability bias (Krizan & Windschitl, 2007)
Goals affecting behavior? Increased commitment (Locke & Latham, 1990) Corresponding plans (Gollwitzer, 1999)
Goals and intentions affect predictions more than behavior (Buehler et al., 1997; Epley & Dunning, 2000, 2006)
e.g., donating blood (Koehler & Poon, 2006)

Savings goals
Preference to minimize expenses and keep expenditures under control
Savings goals should have a greater impact on predicted than actual spending
Self-control (Faber & Vohs, 2004; Rabinovich & Webley, 2007)
Multiple competing goals

Present Research
HYPOTHESES
People underestimate personal spending
Savings goals contribute to this bias The more people want to save the more they predict to
reduce their spending But wanting to save money might not translate into behavior

Study 4 - Manipulating Savings Goals
56 undergraduate students
People who spend money are generally more successful in life.
e.g., Spending money is just one indicator of a spontaneous approach to life, which is linked to career success.
People who save money are generally more successful in life.
e.g., Saving money is just one indicator of a future oriented approach to life, which is linked to career success.

Conclusions and Implications
People routinely underestimate future spending Contributes to literature on money vs. time accounting
Leclerc et al., 1995; Okada & Hoch, 2004; Soman, 2001 “Budget fallacy” similar to “Planning fallacy”
The goal to save money amplifies the optimistic spending bias
Poor predictions may lead to poor budgeting decisions
Ironically, those individuals who are most motivated to improve their finances, may generate the worst financial plans!
