Collective-choice rules aggregate individual choices into a collective decision. This study provides experimental evidence on how collective-choice rules affect institutional design and cooperation behavior in a social dilemma situation. In our setting, groups decide repeatedly on whether to...

We generalize the standard, private values voting model with single-peaked preferences and incomplete information by introducing interdependent preferences. Our main results show how standard mechanisms that are outcome-equivalent and implement the Condorcet winner under complete information or...

How do citizens hold local politicians accountable? I argue that citizens, especially through neighborhood associations, can use bloc voting as a grassroots strategy to pressure local politicians to provide public services. Politicians monitor precinct-level voting, and communities switch their...

We consider the problem of a society that uses a voting rule to select a subset from a given set of objects (candidates, binary issues or alike). We assume that voters' preferences over subsets of objects are separable: Adding an object to a set leads to a better set if and only if the object is...

Blockchain applications are increasingly experimenting with novel governance mechanisms that address issues that are important for their community: resistance to voter fraud in the form a Sybil attack; resistance to the formation of a plutocracy within the community; and, the ability to express...

The receivers share a common prior, wish to implement the outcome that matches the true state and have homogeneous...

We study how seemingly benign changes to voting costs affect electoral turnout, exploiting plausibly exogenous variation in the assignment of polling places in Munich (Germany). Using an event study design, we find that polling place relocations cause a persistent shift from in-person to mail-in...
