Talking across the Aisle with Luca Braghieri and Peter Schwardmann (Abstract)
This paper presents the results of a large-scale experiment featuring natural face-to-face video conversations between Democrats and Republicans in the United States. We investigate both the drivers of self-selection into politically homogeneous conversations (echo chambers) and the effects of co- versus cross-partisan conversations on information aggregation and affective polarization. We identify a relative preference for co-partisan conversations that is explained by participants' pessimism about the hedonic and informational value of cross-partisan conversations. Participants' pessimistic expectations about the extent to which they can learn from counter-partisans are qualitatively correct, as they do by and large learn less in cross-partisan conversations. We show that this gap in learning is driven not by a lower potential for learning anchored in the way knowledge is distributed across party lines, but by the greater difficulty of extracting knowledge from counter-partisans. Participants' pessimism about the hedonic value of conversations is less warranted, as co- and cross-partisan conversations are deemed equally enjoyable ex-post. Moreover, cross-partisan interactions lead to a reduction in affective polarization that lasts for more than three months after the end of our experiment. Taken together, our findings suggest that policies that encourage cross-partisan interactions with the aim of reducing affective polarization and fostering information aggregation might be more successful at the former than the latter objective.
Depression Stigma with Chris Roth and Peter Schwardmann (Abstract, ECONtribute wp)
Throughout history, people with mental illness have been discriminated against and stigmatized. Our experiment provides a new measure of perceived depression stigma and then investigates the causal effect of perceived stigma on help-seeking in a sample of 1,844 Americans suffering from depression. A large majority of our participants overestimate the extent of stigma associated with depression. In contrast to prior correlational evidence, lowering perceived social stigma through an information intervention leads to a reduction in the demand for psychotherapy. A mechanism experiment reveals that this information increases optimism about future mental health, thereby reducing the perceived need for therapy.
Misperceived Effectiveness and the Demand for Psychotherapy with Chris Roth and Peter Schwardmann (Abstract, ECONtribute wp)
R&R at the Journal of Public Economics
While psychotherapy has been shown to be effective in treating depression, take-up remains low. In a sample of 1,843 depressed individuals, we document that concerns about effectiveness are top of mind when respondents consider the value of therapy. We then show that the average respondent underestimates the effectiveness of therapy and that an information treatment that corrects this misperception increases participants’ incentivized willingness to pay for therapy. Information affects therapy demand by changing beliefs rather than by shifting attention. Our results suggest that information interventions that target the perceived effectiveness of therapy are a potent tool in combating the ongoing mental health crisis.
Social Preferences Under the Shadow of the Future with Felix Kölle and Simone Quercia (Abstract)
R&R at Experimental Economics
Social interactions predominantly take place under the shadow of the future. Previous literature explains cooperation in indefinitely repeated prisoner’s dilemma as predominantly driven by self-interested strategic considerations. This paper provides a causal test of the importance of social preferences for cooperation, varying the composition of interactions to be either homogeneous or heterogeneous in terms of these preferences. Through a series of pre-registered experiments (N = 1,074), we show that groups of prosocial individuals achieve substantially higher levels of cooperation. The cooperation gap between prosocial and selfish groups persists even when the shadow of the future is increased to make cooperation attractive for the selfish and when common knowledge about group composition is removed.

Sorting Into Incentives for Prosocial Behavior with Christian. J. Meyer (Abstract, SSRN working paper)
This paper studies incentivized voluntary contributions to a charitable activity.
Motivated by the market for blood donations in Germany, we study a setting where different incentives coexist and agents can choose to donate without receiving monetary compensation. This lets agents reveal and signal their individual preferences through their actions. In a model that interacts image concerns of agents with intrinsic and extrinsic incentives to donate, we show that this setting can bring about efficiency gains in the collection similar to those deriving from self-selection in second-degree price discrimination. We develop a laboratory experiment to test our theoretical predictions under controlled conditions. Results show that a collection system where compensation can be turned down can improve the efficiency of collection. Introducing the choice to be compensated does not crowd out unpaid donations. A significant share of donors chooses to donate without being compensated. Heterogeneity in treatment effects suggests gender-specific preferences over signaling.
