C Cotton, B Hickman, J List, J Price, & S Roy (2026), Why Don’t Struggling Kids Do Their Homework? Disentangling Motivation and Study Productivity in a Model of Human Capital Investment, Journal of Political Economy

Performance gaps among struggling students reflect weak support and lack of opportunity more than lack of motivation. Efforts to help them must ensure effort pays off — not just incentivize more of it. [NBER wp27995 & wp37274]

C Cotton & L Scholle-Cotton (2026), The AI Expertise Paradox, Issues in Science and Technology (National Academy of Sciences)

A forum article introducing the AI Expertise Paradox: The technology that helps novices perform more like experts today can prevent them from becoming the experts of tomorrow. Featured in Smith Business Insight.

The first controlled trial of financial incentives for peer reviewers at a medical journal. Payments modestly improved turnaround times without reducing review quality. The issue’s feature article, accompanied by a journal forward & editorial, and covered in Queen’s Gazette, Nature, Nature again, and several discussion pieces at CCM.

L Corazzini, C Cotton, E Longo, & T Reggiani (2024), Coordinated selection of collective action: Wealthy-interest bias and inequality, Journal of Public Economics

Wealthy-interest policy biases can emerge from the basic structure of collective action — without lobbying, corruption, or any of the mechanisms typically assumed to drive them. An application of our multiple threshold public goods framework (Corazzini et al. 2015) to study cooperation among groups with only partially aligned preferences.

C Cotton, B Hickman, & J Price (2022), Affirmative action and human capital investment: Evidence from a randomized field experiment, Journal of Labor Economics

Affirmative action policies shift the distribution of effort and performance, increasing average outcomes while reducing the effort of the most capable minority students. The first controlled field experiment of a large-scale contest. [NBER wp20397; featured in Quartz, FiveThirtyEight, The Chronicle of Higher Education]

M Agranov, C Cotton, & C Tergiman (2020), Persistence of Power: Repeated multilateral bargaining with endogenous agenda setting authority, Journal of Public Economics

In repeated group bargaining, power concentrates over time even when members have equal formal standing — and the standard theoretical equilibrium concept fails to predict how groups actually behave. [Lead article]

R Boleslavsky, C Cotton, & H Gurnani (2017), Demonstrations and price competition in new product release, Management Science

Trial periods, return policies, and niche marketing strategies allow firms to credibly communicate product quality to skeptical buyers. A Bayesian persuasion model showing why these practices are profitable.

L Corazzini, C Cotton, & P Valbonesi (2015), Donor coordination in project funding: Evidence from a threshold public goods experiment, Journal of Public Economics

The first multiple-threshold public goods experiment — providing a framework for studying how groups consolidate their collective attention around different actions, policies, and initiatives. Foundational work for understanding cooperation between organizations, communities, and coalitions.

R Boleslavsky & C Cotton (2015), Grading standards and education quality, American Economic Journal: Microeconomics

The most selective schools inflate grades while relying on their reputations to place students. Other schools must grade more accurately to keep their strongest students competitive in the job market. The first model of competitive Bayesian persuasion, where institutions compete by strategically producing and communicating evidence. [AEA Research Highlight, Vox-EU]

R Boleslavsky & C Cotton (2015), Information and extremism in elections, American Economic Journal: Microeconomics

Uncertainty about how voters’ opinions of candidates will evolve over the course of a campaign undermines the median voter theorem and party incentives to run more moderate candidates. [The Washington Post, IB Times, Discovery News].

C Cotton (2013), Submission fees and response times in academic publishing, American Economic Review

Journals may use both submission fees and slow response times to prevent long-shot submissions and maintain reasonable review loads. My first work on academic publishing and the science of science.

C Cotton (2012), Pay to play politics: Informational lobbying and contribution limits when money buys access, Journal of Public Economics

When political contributions buy access to politicians, those with access (targeted by politician rent seeking) do not necessarily benefit from politician attention. Campaign finance reform can improve welfare. One of the first models of informational lobbying and access.

C Cotton (2009), Should we tax or cap political contributions? A lobbying model with policy favors and access, Journal of Public Economics

Taxing political contributions may be more effective than donation limits when politicians allocate their attention based on political contributions. One of the first models of informational lobbying and political access. [Lead article]
