How institutions shape behaviour and policy

I use economics to understand crime, policing, political decision-making and public interventions—and work with partners to test what makes a difference.

§ 01.1 Research journey

From political economy to policing, justice and health

I trained as an applied economic theorist, studying coalitions, public choice and political incentives. Those questions still inform my work on elections, conflict, media and group formation. Collaborations in policing, justice and health have since led me to new questions where economic thinking can make a practical contribution.

Since 2012, I have worked with UK police and criminal-justice organisations on diversion, youth violence, domestic abuse, knife crime and investigative decisions. Increasingly, I also study how violence and childhood adversity affect health and wellbeing over the life course.

For me, evaluation is not simply a verdict on whether something “works”. I want to know who benefits, what it costs, how it is implemented and whether the approach can succeed elsewhere. That is why I combine economic evaluation with implementation research and co-production.

§ 01.2 Themes

The questions I pursue

These themes overlap, and many projects bring together colleagues in economics, criminology, health and public services.

  • 01

    Crime, policing & criminal justice

    I study how criminal behaviour, police practice, prosecution and the design of justice institutions respond to incentives, evidence and institutional constraints.

    • Economics of crime

    Political economy & public choice

    I examine how electoral rules, coalitions, information and media shape political incentives, leaders’ choices and collective outcomes.

    • Coalitions
    • Elections
    • Public choice
    • Media & information
  • 03

    Policy evaluation & public value

    I evaluate public interventions using experiments, cost–benefit analysis, administrative data and mixed methods, working with practitioners and communities.

    • Economic evaluation
    • RCTs
    • Co-production
    • Public services
  • 04

    Violence, health & wellbeing

    With colleagues across economics, health and social science, I study the long-run health and economic consequences of domestic abuse, childhood maltreatment and gender-based violence.

    • Domestic abuse
    • Public health
    • Gender-based violence
    • Wellbeing
  • 05

    • Conflict
  • 06

    Work, technology & social change

    I examine how automation and technological change are reshaping work, skills, organisations and inequality, including through the book Work 3.0.

    • Future of work
    • Automation
    • Technology
    • Inequality
