GAMESTOP, A COMPANY THAT WAS PRESUMED DEAD DUE TO SHRINKING PROFITS OFITS BRICK-AND-MORTAR BUSINESS MODEL, HIT THE HEADLINES BECAUSE OF ASHORT SQUEEZE OF ITS STOCK PRICE. THE POPULAR OPINION REPORTED BY MAIN-STREAM MEDIA SUGGESTED THAT THE GAMESTOP FRENZY WAS EXCLUSIVE TO YOUNGAND INEXPERIENCED INVESTORS GATHERING ON THE SOCIAL MEDIA PLATFORMREDDIT. IN CONTRAST, OUR RESULTS INDICATE THAT ALSO MORE EXPERIENCEDRETAIL INVESTORS IN GERMANY PARTICIPATED.
We investigate the link between Big Five personality traits and the marginal propensity to consume (MPC) for users of a German financial account aggregator app. We use 1,700 survey responses and transaction data of 56,000 app users to assess whether Big Five personality traits help explain MPC heterogeneity. We find that extraversion corresponds to an increase in consumption whereas agreeableness and neuroticism correspond to a decrease in consumption. We test this with trust and risk preferences and find that risk indicates more explanatory power in consumption response than the Big Five. Our findings help policy makers target individuals more efficiently.
What does your personality reveal about your financial behavior? Evidence from a FinTech experiment
(2022)
We co-operate with a German financial account aggregator (FAA) and conduct a personality survey with 1,700 app users. We combine the survey results with their anonymized transaction data and investigate links between personality traits and spending behavior. Observing many lottery windfalls in our dataset and treating these incidents as real-life experiments, we ask: what do individuals do with unexpected income changes? Our findings suggest that highly extraverted individuals tend to overspend in response to lottery windfalls.
