“Temptation: Immediacy and Certainty”

An option is especially tempting when it is both immediate and certain. I conduct an online experiment with longitudinal real-effort provision to test this hypothesis and study the effect of risk on present bias. My design permits dynamic inconsistency by having some decisions in advance of real-effort exertion, as well as decisions when the work is imminent. This novel design methodologically eliminates two types of risk created by the random incentive scheme, while still identifying present bias. When a decision is implemented with certainty, I find that the number of present-biased individuals is no different, but the intensity of their present-bias is far greater than under risk.

“Can targeted messages reduce COVID-19 vaccination hesitancy? Results from a survey experiment”

To end the COVID-19 pandemic without millions of deaths, the United States needs very high uptake of a vaccine. We hypothesized that we can apply theories of social identity to design targeted messaging to more effectively reduce vaccine hesitancy among highly-resistant subpopulations, such as African Americans and political conservatives. Our messages present risks of COVID-19 to oneself, risks to others, an endorsement of the vaccine by a celebrity, and benefits of the vaccine. We test whether respondents report greater intent to take a hypothetical vaccine after receiving messages with greater extent of customization to their demographic segment. We find no support for the hypothesis that customized messages or endorsers may reduce vaccine hesitancy among our segments of interest. We find suggestive evidence that a vaccine endorsement from Dr. Fauci reduces stated intent to vaccinate among conservatives.

“Wage Policies, Incentive Schemes, and Motivation”

We review experimental and field evidence of how effort and performance in the labor market is affected by financial incentives and non-monetary motivators. Especially small incentives may crowd-out intrinsic motivation, while large incentives may cause choking. A wide variety of social preferences affect labor supply, including gift exchange, fairness, and reciprocity.

Work in progress

“Rational inattention under risk and ambiguity”

ORSEE tools

Assorted tools to help manage the subject pool in ORSEE, software widely used by experimental economists to run sessions. Code and slides are available on GitHub.

Teaching experience

I look forward to using in-class experiments as an interactive pedagogical tool!

About me

I was born and raised in Wyoming and Montana. Some of my favorite places include the Beartooth and Bighorn Mountains, and the entire Absaroka region—all in the vicinity of Yellowstone National Park, which my family simply called “the park.” I studied philosophy, economics, and mathematics as an undergraduate at Montana State University in Bozeman.

I independently learned about web engineering (various programming languages, database systems, and operating systems) in my younger years. I took a challenging and rewarding web development contract with a start-up after my undergraduate program. Once I completed my Master's degree in economics at Montana State University in Bozeman, I worked full-time as a professional software engineer. I am grateful to have had the opportunity to pursue my Ph.D. in economics at the University of California at Santa Barbara.

I am a longtime Unix-like operating system user (twenty years using OpenBSD and FreeBSD) who indents code with four spaces in Vim (a text editor).
