The Value of Consensus: Information Aggregation in Committees with Vote-Contingent Payoffs (2017)—R&R at the Review of Economic Studies
(Joint with Yves Breitmoser)
Existing theoretical and experimental studies have established that unanimity is a poor decision rule for promoting information aggregation. Despite this, two-sided unanimity (consensus) is frequently used in committees making decisions on behalf of society. This paper shows that a consensus rule can facilitate truthful communication and optimal information aggregation when voters face consequences not only for the outcome of the collective decision, but also for how they personally voted. Theoretically, we show that majority rule suffers from a free-rider problem in this setting, since agents' votes are not always pivotal. Consensus mitigates free-riding since responsibility for the committee's decision is equally distributed across all agents. We test our predictions in a controlled laboratory experiment. As predicted, if consensus is required, subjects are more truthful, respond more to others' messages, and are ultimately more likely to make the optimal decision. Our work therefore provides a rationale for consensus rule in settings where committee members are held accountable, formally or informally, for their individual voting decisions.

Dynamic Reform of Public Institutions: A Model of Motivated Agents and Collective Reputation (2017)
When motivated agents value the collective reputation of their place of employment, steady-state equilibria with both high and low aggregate motivation (reputation) in the mission-oriented sector exist. Since the effect of higher wages on motivation is negative for a high-reputation institution, but positive for a low-reputation institution, transitioning to a high-reputation steady state requires an initial wage increase to crowd motivated workers in, followed by a wage decrease to crowd non-motivated workers out.

The Political Economy of Multilateral Aid Funds (2016)
(Joint with Jenny Simon)
When donor countries commit to allocate foreign aid via collective decision making, recipient countries are induced to compete over ex ante investments in good governance. Majority rule induces stronger competition between recipients, but limits aid to a strict subset of recipient countries, which implies that unanimity is often optimal.

The Link between Partisan Voting and Polarized Social Identity (2017)
(Joint with Dominik Duell)
We provide theoretical and experimental evidence that social polarization influences voting through an expressive channel, as voters become more likely to vote instinctively, and through an instrumental channel, as voters expect candidates to take decisions that are favorable to their partisan in-groups. Our results confirm that affective polarization decreases the electoral prospects of high-quality candidates, as voters become more likely to choose based on identity rather than ability. [Paper]
Voting in Large Committees with Disesteem Payoffs: A ‘state of the art’ model (2017)
(Joint with Rune Midjord and Tomás Rodríguez Barraquer)
If committee members receive idiosyncratic payoffs linked to the correctness of their individual vote, then the standard model predicts that a committee will always accept innovations with too high a probability. However, a natural variation of the model predicts that the committee may accept or reject the innovation with too high a probability depending on the relative size of the payoffs for correctly voting to accept/reject.

Centralized Fiscal Spending by Supranational Unions (2017)
(Joint with Jenny Simon)
When countries with asymmetric incomes bargain over a central budget, an inefficient allocation results since bargaining power is linked to contributions. This link explains why EU resources are diverted to low-productivity projects in high-income countries.

A Note on Empathy in Games (2015)
(Joint with Jan Grohn and Steffen Huck)
We illustrate how some insights from the psychological literature on empathy can be incorporated into a standard utility framework, and demonstrate the potential interaction of beliefs and utility through the channel of empathy.

Get Out The Vote: How Policies That Encourage Voting Change Political Outcomes (2012)
I consider a joint model of voter turnout and candidates' choice of political positions and show that lowering the net expense of voting reduces political polarization.

Institutionalizing Eurozone Exit: A modified NEWNEY approach (2012)
(Joint with Steffen Huck)
We argue that the Eurozone needs an institutional exit mechanism to enhance Eurozone stability, and propose modifications to the Dobbs' NEWNEY mechanism.
