March 2015How Individuals Smooth Spending: Evidence from the 2013 Government Shutdown Using Account Data
with Michael Gelman, Matthew D. Shapiro, Dan Silverman, Steven Tadelis: w21025
Using comprehensive account records, this paper examines how individuals respond to a temporary drop in income following the 2013 U.S. Federal Government shutdown. Affected employees saw their income decline by 40% on average, which was recovered within two weeks. Despite having no effect on lifetime earnings, spending dropped sharply, implying a naïve estimate of the marginal propensity to spend of 0.57. This estimate overstates how consumption responded. To smooth consumption, individuals adjusted by delaying recurring payments such as mortgages and credit card balances. Those with the least liquidity struggled most to smooth spending and were left holding more debt months after the shutdown.
May 2014The Distributional Preferences of Americans
with Raymond Fisman, Pamela Jakiela: w20145
We measure the distributional preferences of a large, diverse sample of Americans by embedding modified dictator games that vary the relative price of redistribution in the American Life Panel. Subjects' choices are generally consistent with maximizing a (social) utility function. We decompose distributional preferences into two distinct components - fair-mindedness (tradeoffs between oneself and others) and equality-efficiency tradeoffs - by estimating constant elasticity of substitution utility functions at the individual level. Approximately equal numbers of Americans have equality-focused and efficiency-focused distributional preferences. After controlling for individual characteristics, our experimental measures of equality-efficiency tradeoffs predict the political decisions of our ...
How Did Distributional Preferences Change During the Great Recession?
with Raymond Fisman, Pamela Jakiela: w20146
We compare behavior in experiments measuring distributional preferences during the "Great Recession" to behavior in identical experiments conducted during the preceding economic boom. Subjects are drawn from a diverse pool of students whose socioeconomic composition is largely held constant by the university, mitigating concerns about differential selection across macroeconomic conditions. Subjects exposed to the recession are more selfish and more willing to sacrifice equality to enhance efficiency. Reproducing recessionary conditions inside the laboratory by confronting subjects with losses has the same impact on distributional preferences, bolstering the interpretation that economic circumstances, rather than other factors, are driving our results.
February 2011Who Is (More) Rational?
with Syngjoo Choi, Wieland Müller, Dan Silverman: w16791
Revealed preference theory offers a criterion for decision-making quality: if decisions are high quality then there exists a utility function that the choices maximize. We conduct a large-scale field experiment that enables us to test subjects' choices for consistency with utility maximization and to combine the experimental data with a wide range of individual socioeconomic information for the subjects. There is considerable heterogeneity in subjects' consistency scores: high-income and high-education subjects display greater levels of consistency than low-income and low-education subjects, men are more consistent than women, and young subjects are more consistent than older subjects. We also find that consistency with utility maximization is strongly related to wealth: a standard deviati...
