We study how healthcare subsidies and improved information affect over- and under-use of primary healthcare in a randomized control trial of 1544 children in Mali. In a dynamic model of healthcare demand, misuse relative to policymaker preferences (here given by WHO care-seeking standards)...

We study the impact of subsidies (which remove cost barriers) and healthworker visits (which remove informational barriers) on over- and underuse of primary care, using a randomized control trial across 1532 children in Mali. Providing children with access to primary healthcare is an important...

Two of the most well known regularities observed in preferences under risk and uncertainty are ambiguity aversion and the Allais paradox. We study the behavior of an agent who can display both tendencies simultaneously. We introduce a novel notion of preference for hedging that applies to both...

We study the pattern of correlations across a large number of behavioral regularities, with the goal of creating an empirical basis for more comprehensive theories of decision-making. We elicit 21 behaviors using an incentivized survey on a representative sample (n = 1;000) of the U.S....

We use four incentivized representative surveys to study the endowment effect for lotteries in 4,000 U.S. adults. We replicate the standard finding of an endowment effect–the divergence between Willingness to Accept (WTA) and Willingness to Pay (WTP), but document three new findings. First, we...

Incentivized experiments are commonly used to estimate marginal rate of intertemporal substitution (MRS) in the lab and in the field, and to make inferences about subject's time preference. This paper considers the implications of an integrated model of behavior in which individuals are subject...

Willingness to pay (WTP) and willingness to accept (WTA) a monetary amount for a lottery should be closely related. In data from an incentivized survey of a representative sample of 3,000 U.S. adults, we find that WTA and WTP for a lottery are, at best, weakly correlated. Across all respondents,...
