    Poverty and Economic Decision-Making: Evidence from Changes in Financial Resources at Payday (with Leandro S. Carvalho and Stephan Meier) [PDF] [Appendix]
    Revision Requested, American Economic Review

    Abstract

    We study the effect of financial resources on decision-making. Lowincome U.S. households are randomly assigned to receive an online survey before or after payday. The survey collects measures of cognitive function and administers risk and intertemporal choice tasks. The study design generates variation in cash, checking and savings balances, and expenditures. Before-payday participants behave as if they are more present-biased when making intertemporal choices about monetary rewards but not when making intertemporal choices about non-monetary real-effort tasks. Nor do we find before-after differences in risk-taking, the quality of intertemporal decision-making, the performance in cognitive function tasks, or in heuristic judgments.

    Dynamically Optimized Sequential Experimentation (DOSE) for Estimating Economic Preference Parameters (First author, with Colin F. Camerer and Michelle Filiba) [PDF]
    Revision Requested, American Economic Review

    Abstract

    Dynamically optimized sequential experiments (DOSEs) for estimation of risk preferences start with a distribution of beliefs about risk preference parameters, and a set of questions, then dynamically choose the question that maximizes information gain considering previous answers. Applying the method to the 10-question set of Holt and Laury (2002) and the 140-question set of Sokol-Hessner et al. (2009) to measure risk-aversion and loss-aversion shows that DOSE sequences create a 50-70% increase in speed of inference about parameter from fewer questions. Simple DOSE designs could be useful in complex environments with highly-distractible groups like internet groups, children, CEOs and monkeys.

    Patience Auctions: The Impact of Time vs. Money Bidding on Elicited Discount Rates (with Christopher Y. Olivola) [PDF]

    Abstract

    We introduce, test, and compare two auction-based methods for eliciting discount rates. In these “patience auctions”, participants bid the smallest future sum they would prefer -or- the longest time they would wait for a reward, rather than receive a smaller, immediate payoff. The most patient bidder receives the delayed reward; all others receive the immediate payoff. These auctions allow us to compare discounting when participants’ attention is focused on the temporal vs. monetary dimension of delayed rewards. We find that preferences are less hyperbolic (i.e., closer to exponential) and exhibit less present bias under time-bids, compared to money-bids. Furthermore, we find that the estimated discount parameters in the three most commonly used discount functions (exponential, hyperbolic, and quasi-hyperbolic) differ across these two theoretically equivalent bidding methods (time-bids vs. money-bids). Specifically, our participants tend to show more impatience under time-bids. To our knowledge, this paper is the first to directly compare time vs. money preference elicitations, within the same subjects, using an incentive-compatible mechanism.

    Anticipating Information Projection: An Experimental Investigation (with David Danz and Kristof Madarasz)

    Abstract

    We investigate whether people predict the biases of others with an experiment that matches agents with informed or uninformed principals. While the agents' beliefs are well-calibrated regarding the average task performance, they also correctly believe that by having access to additional information, principals project their information onto others and overestimate the likelihood of success. The agents’ preference for a payoff that is independent of the principal’s evaluation when matched with an informed principal is consistent with anticipating this information projection. We also use the agents’ stated first- and second-order beliefs to estimate the extent of information projection and its anticipation.
