“Temptation: Immediacy and Certainty”

Is an option is especially tempting when it is both immediate and certain? To study the effect of risk on present bias, I conduct an online experiment in which workers allocate about thirty minutes of real-effort tasks between two weeks. I compare choices made two days before the first workday against choices made when work is imminent. In baseline treatments, one choice is randomly implemented; meanwhile, one treatment implements a particular allocation with certainty. By assuming that effort costs are not affected by the mechanism (and thus independent of risk preferences), my novel design permits estimation of present bias using a decision with a consequence both immediate and certain. I find the average intensity of present bias is far greater under certainty than under risk. I find no evidence that present bias is more pervasive among individuals, suggesting instead that present-biased individuals become more myopic.

“Can theories of social identity help increase uptake of a COVID-19 vaccine?”

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.

“Idiosyncratic rational inattention”

We present behavioral biases that occur in a variety of common learning environments.

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

Courses that I have taught extensively and honed:

  • Microeconomics, intermediate
  • Finance, upper-division

Some notable courses I have also taught (with a complete list on my CV):

  • Econometrics, Master's sequence
  • Macroeconomics, intro and intermediate
  • History of Economic Thought

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 return to academia and pursue my Ph.D. in economics at the University of California at Santa Barbara.

I enjoy yoga, bouldering, cycling, and reading economics articles at the beach. I also shoot film photography—sometimes only using a disposable camera! I indent code with four spaces in Vim; I grew up on OpenBSD and FreeBSD.
