Intrapersonal Comparisons as Interpersonal Comparisons, with Daniel Reck.
We consider the optimal policy problem of a benevolent planner, who is uncertain about an individual’s true preferences because of inconsistencies in revealed preferences across be- havioral frames. We adapt theories of expected utility maximization and ambiguity aver- sion to characterize the planner’s objective, which results in welfarist criteria similar to social welfare functions, with intrapersonal frames replacing interpersonal types. Under paternalistic risk aversion or ambiguity aversion, a policy is less desirable to the planner, holding all else fixed, when it leads to more disagreement about welfare from revealed pref- erences. We map some examples of behavioral models into our framework and describe how this notion of robustness plays out in applied settings.
A Welfare Analysis of Public Housing Allocation Mechanisms, with Neil Thakral.
When allocating scarce resources such as public housing units to applicants in a waiting list, welfare depends on applicants’ preferences (match values and waiting costs) as well as their choices (which may involve errors). To trade off between allowing agents to wait for better matches and prioritizing agents with high waiting costs, allocation mechanisms impose restrictions on choices. Public housing allocation mechanisms in the UK restrict the set of available options that an applicant may accept, while mechanisms in the US restrict the number of times an applicant may reject. We examine how these different ways of restricting choices influence welfare, both theoretically and empirically. Using data on preferences for public housing in the US and the UK, we show how welfare compares under rationality and explore the sensitivity of the mechanisms to choice-error.

The Social Determinants of Mental Health, with Jon Kolstad, Will Parker and Johannes Spinnewijn.
This paper documents and analyzes the relationship between socio-economic factors and key measures of mental health. We demonstrate a sharp deterioration of mental health below an income threshold around the poverty line, while the impact of income beyond the threshold level are remarkably flat. The persistence of low socio-economic status further increases the risk of poor mental health. We find that the socio-economic gradients are strongest for working-age individuals, are not driven by access to health care and mostly explained by work status. Big economic events such as physical health shocks and job losses seem not to contribute much to the overall gradient. Rather, the evidence suggests social drift as the primary mechanism: those with poor mental health sort into lower incomes over the lifecycle.
Rebuilding Lives: Integrating Mental Health and Economic Recovery in Climate Disaster Response, with Amen Jalal and Pol Simpson.
Disaster recovery often focuses on rebuilding physical infrastructure, overlooking the mental health impact of traumatic events like floods. In Pakistan, where flooding in 2022 submerged a third of the country under water and lasted up to 8 months, over one in five flood affectees report severe psychological distress 2 years later. When asked about the long-term consequences of flooding, worsened mental and physical health is the second most commonly reported impact, following housing damage (Jalal and Simpson, 2024). Ignoring mental health in reconstruction may prolong the socio-economic impact of disasters by limiting individuals' ability to work, plan, and recover. This project studies the interaction between physical and psychological recovery in flood-affected communities, by fielding a locally developed mental health literacy initiative, cross-randomised with a housing reconstruction program. This 2x2 design allows us to compare the benefits of mental health support against the standard infrastructure-focused approach, and explore complementarities. Our findings aim to measure the non-economic losses and damages of climate catastrophes, and inform more holistic disaster recovery policies that address both physical and psychological needs.
