We asked a group of Americans to estimate the current state of economic inequality in the United States. On average, they under-estimated the true extent of inequality by over 200%. Why do people get this so wrong? In this work, we analyze the pervasive misperceptions about economic inequality. In 9 experiments with 3,599 Americans, we identify cognitive biases that influence how people evaluate economic distributions.

Income volatility and impatient financial decisions

How do unpredictable income streams influence our financial choices? We analyze panel data tracking 5,106 Americans over 27 years and find that experiencing more volatile year-over-year income swings leads to more impatient financial decision-making. In a series of follow-up studies with another 1,167 participants, we find that month-over-month income volatility also has an even stronger effect on financial choices, leading people to over-spend and under-save. We analyze the implications and how we might design fintech tools to help people manage increasingly volatile incomes.
