What got you interested in economics and in particular, topics like charitable giving and organ donation?

I became smitten by economics in high school when I was struck by how its relatively simple models could explain what seemed like complex phenomenon (e.g. why movie theater popcorn was so expensive, a pressing question for a cash-strapped high school student). In college, I was exposed to—and impressed by—the rigorous empirical methods that economists have in their toolbox, including econometric techniques that allowed researchers to generate causal inference from data that otherwise seemed intractable. Towards the end of college, I began using experimental methods, which allow researchers to tackle important questions in a particularly well-identified way. By the time I graduated from undergrad, I was hooked on economics. When I started conducting my own research, I gravitated towards topics like charitable giving and organ donation because I am fundamentally interested in what motivates people to privately provide public goods and to, more generally, privately take costly actions with positive externalities. To me, this is a particularly compelling question since it is simultaneously important for the functioning of society and is a question for which economics does not already have a clear answer.

What is one current research project that you’re particularly excited about?

I am currently working on a project (funded by J-PAL) in which we are evaluating the welfare implications of an intervention trying to encourage energy conservation. The idea is that learning that I am over-consuming energy (e.g. relative to my neighbors) might make me conserve more but simultaneously decrease my welfare if that information makes me feel guilty or otherwise bad about myself. Similarly, learning that I am under-consuming might increase my welfare by making me feel accomplished or otherwise good about myself, even if it does not affect my energy consumption. We’re interested in measuring the magnitude of these effects and hoping to get other researchers thinking about the welfare implications of these types of behavioral interventions.

What is your “dream evaluation”? (It doesn’t have to be feasible!)

Researchers who study charitable giving often wonder about the extent to which there is crowd out in giving. In particular, we wonder whether an intervention that induces someone to donate more to a charity today will lead that person to donate less to the charity in the future, to donate less to other charities, or to be less generous in other domains (e.g. volunteering less or being less nice to their neighbors). We do our best to look for effects of interventions on these related outcomes, but it is incredibly difficult to observe the myriad opportunities an individual has to be generous, particularly in non-monetary ways.

My dream evaluation would be to induce extra giving to a charity through an RCT and follow those in the treatment and control groups to see what kinds of effects the induced extra donation to the charity has on their generosity in other domains—including everything from donations to other charities, to volunteering, to behavior in interpersonal relationships. We might see crowd out of the form described above (e.g. due to a fixed charitable budget or a moral license to be bad after having been generous). Alternatively, we might see crowd in where being induced to be generous in one setting makes people decide to be donate more to other charities and be more generous in other domains. This is an empirical question that teaches a lot about charitable behavior that I would love to be able to answer.

J-PAL North America seeks to reduce poverty by ensuring that policy is informed by scientific evidence. We do this through research, outreach, and training. We collaborate with decision-makers to generate clear, scientific evidence on which approaches work and why. We catalyze and support randomized evaluations, communicate evidence to help translate research into action, and build policymakers’ capacity to create and use evidence.
