Altruism begets altruism (with Robert Slonim) [pdf] 
Revision Requested at The Economic Journal.
​

Guided by Bem's (1972) self-perception theory, we design an experiment to ask whether morally-motivated behaviour, e.g., charitable giving, is history-dependent. Using a popular policy nudge, the default option, we exogenously vary altruism "now" and show that the nudge-induced choice to give "now"  causes a 41 percentage point (or 200%) increase in the probability of giving "later"; that is, altruism begets altruism. We further show that, consistent with self-perception theory, the  choice to behave altruistically "now", rather than the nudge itself, is the crucial element in the causal relationship.  These findings are consistent with positive path-dependence, which we interpret as moral consistency.​

Exploration & Self-Selection: Revisiting Roy (with Barton Hamilton) [pdf]
Reject & Resubmit at Games and Economic Behavior.

We study how selection shapes exploratory versus exploitative behavior. Using a laboratory experiment, we decompose Roy's (1951) theory of selection and study the effect of traits on innovative behavior when information type is assigned versus when it is selected. Consistent with theory, when information type is  assigned, we find that  (1) there are distinct behavioral patterns leading to earnings' disparities  and (2) the returns to personality traits are ambiguous, and significantly depend on the type of information assigned. By contrast, when individuals self-select their information type, we show that they leverage their trait-based advantage, their information choice is optimal and, as predicted by Heckman & Honore (1990), the earnings' disparities disappear.

Self-Serving Truthfulness (with Robert Slonim & Franziska Tausch) ​[pdf]
Under Review.

We conjecture and experimentally examine a novel explanation for dishonesty, self-serving truthfulness. We conjecture that when the objective truth is uncertain, people will provide self-reports that financially benefit them. To examine \emph{self-serving truthfulness}, we asked a sample of U.S. car owners to respond to an auto insurance underwriting questionnaire that affects their price of insurance (i.e., premium), and investigated how financial incentives affect the honesty of their responses. We find, consistent with the current literature, that people have a strong preference for truthfulness, but only when they are confident of the objective truth. However, when people are not completely certain of the objectively correct response, significant dishonesty occurs in a self-serving manner. We also find that self-serving truthfulness is not strategic and thus distinct from self-deception. Further, interventions aimed at mitigating dishonesty by targeting commonly used strategies to justify dishonesty, e.g., moral wiggle room, consequence attenuation, and attenuation through victim deservingness, are minimally effective.

In Progress:
Vice and Virtue Behaviours: Substitution and Non-Substitution Effects (with Alex Cornish)
We examine how tax policy that encourages charitable giving spills over into other morally motivated behaviours. We examine behaviours that are seemingly unrelated to charitable giving, but that are easily classified as virtuous or vice behaviours—exercise and smoking—to study how people jointly engage in virtuous behaviours (charitable giving and exercise) as well as how people jointly engage in a mixed or vice-virtue bundle (charitable giving and smoking). Using the Panel Study of Income Dynamics, we estimate marginal tax rates for 17,181 individuals over 5 panels from which we can calculate the effective price of giving to charity. We then estimate the structural model developed by Dinardo & Lemieux (1992, 2001) to disentangle substitution effects (i.e., changes in behaviour that arise from changes in relative prices) from non-substitution effects (i.e., changes in behaviour that arise through behavioural channels). Contrary to reduced form results which confound substitution and non-substitution effects, we find that charitable giving and exercise are substitutes in consumption, but the positive non-substitution effect dominate, rendering a positive relationship between charitable giving and exercise. Charitable giving and smoking are also substitutes in consumption and the negative non-substitution effects contribute to a negative relationship between charitable giving and smoking. Together, we interpret both the dominance and the direction of the non-substitution effects as evidence consistent with moral consistency.

Learning to Give: Professional versus Consumer Reviews
We estimate and compare the effect of information from professional versus consumer reviews on consumer behavior. We do so in a pro-social context and examine how information about a charity's effectiveness impacts willingness to donate. We move beyond the existing literature to examine how two distinct sources of information, professional reviews versus consumer reviews, differentially affect individual's willingness to give. We find that individuals place significantly more value on professional reviews than on equivalent consumer reviews. However, when individuals receive a second piece of information they update their willingness to donate similarly regardless of the source: individuals' willingness to donate is unaffected by ``good news" about the charity, but significantly negatively affected by ``bad" news.
