Amid increased attention toward legislator moderation and election reform, this paper examines the relationship between US primary election policies and electoral outcomes from 1976 to 2020. To accomplish this, I use a difference-in-differences approach to investigate whether adopting less restrictive primary systems impacts legislator extremism and voter turnout. I find that expanding ballot access causes legislator ideology to shift toward the median voter. This moderating effect is even more pronounced for newly elected representatives and is driven mainly by non-partisan primary systems. Over the same period, I estimate a decrease in general election participation following the adoption of "open-type" primary systems. I present evidence suggesting voter indifference as the likely cause of this negative effect, stemming from a smaller ideological gap between candidates. This paper offers a comprehensive view of primary election policies, underscoring the balance between enhancing representation and maintaining voter engagement.
Adult ADHD, Stimulant Medication, and Labor Market Outcomes
Treatment of Attention-deficit hyperactivity disorder (ADHD) --- a neurodevelopmental disorder associated with inattention and hyperactivity --- primarily consists of the prescription of stimulant medication. To study the relationship between stimulant medication and labor market outcomes in people with ADHD, I use linked employment and pharmaceutical data from the Medical Expenditure Panel Survey (MEPS) and leverage individual-level variation to estimate a two-way fixed effects regression. I find limited evidence to support a causal relationship between prescription behavior and employment, real wages, or weekly labor hours.
Trust and AI (with Ethan Holdahl, Conner Weigand, and Jiabin Wu) (in progress)
This study investigates whether the recent development of AI, namely ChatGPT, can help to facilitate the establishment of trust among humans. To achieve this, we employ Charness and Dufwenberg's two-player trust game from behavioral game theory through lab experiments administered via Prolific.
