We look at the effect of transparency on the incidence of costly back-scratching in a laboratory setting by implementing player identification via photographs. In our experimental design players have an incentive to form bilateral alliances in which they favour their partner at the expense of...

We develop a theory of information flows and political regime change, when citizens use information and communication technologies (ICTs) for both information acquisition and protest coordination. Governments can respond by obfuscation of citizens' signal or by restricting access to ICTs used...

Behavioral economics characterizes decision-makers using psychologically-informed models. Cognitive science produces psychologically-informed models. Why don't these disciplines talk more? Here, I present several arguments for why cognitive science should inform behavioral economics — it...

We develop a finite random assignment model where players know either their cardinal or their ordinal preferences and may make cardinal or ordinal reports to an assignment mechanism. Under truthful reporting, we find that all mechanisms that disregard the cardinal information in players' reports...

Reasonable and equitable water resource decision-making is at the core of good governance around the world. Sustained water collaboration is an antidote to foreign relations disintegration. Lack of water quality and quantity policies can lead to water insecurity for everyone, yet bureaucratic...

In recent years, many social scientists have claimed that trust plays an important role in economic and social transactions. Despite its proposed importance, the measurement and the definition of trust seem to be not fully settled, and the identification of the exact role of trust in economic...

Politicians seeking reelection need voters to know what they have done for them. Thus, incentives may arise to spend more money where media coverage is higher. We present a simple model to explain the allocation of public spending across jurisdictions contingent on media activity. An incumbent...

A ranking over a set of alternatives is an aggregation of experts' opinions (AEO) if it depends on the experts' assessments only. We study both those rankings that result from pooling Bayesian experts and those that result from pooling possibly non-Bayesian experts. In the non-Bayesian case, we...

We consider a dynamic game of private provision of a discrete public good. In our model, a group of agents contributes to a project over time, which is completed once the cumulative contributions reach a threshold. Provided that this occurs prior to a prespecified deadline, each agent receives a...

We analyze a game in which a group of agents exert costly effort over time to make progress on a project. The project is completed once the cumulative efforts reach a pre-specified threshold, at which point it generates a lump sum payoff. We characterize a budget balanced mechanism that induces...
