RECENT PAPERS

 

Contestable Norms with Mikhail Safronov (new version)

·         To be sustainable without external enforcement, social norms, contracts, and other agreements must include provisions not only to deter violations but also to address challenges to move to other norms, contracts, or agreements.

·         We introduce contestable norms, which achieve both objectives, analyze their conceptual foundation, efficiency, stability, design, and evolution, and characterize their payoffs.

·         Contestable norms may be inefficient, no matter how frequent agents’ interactions and proposals, to an extent determined by the amount of conflict inherent in agents’ strategic environment.

·         The analysis sheds new light on the efficient institution hypothesis and the renegotiation paradox.

 

Judicial Mechanism Design with Ron Siegel (new version)

·         When the suspect of a crime is arrested, he enters a judicial mechanism whose outcomes include evidence against him and a sentence

·         We consider the optimal design of judicial mechanisms for several notions of welfare distinguished by their treatment of deterrence

·         The optimal mechanisms present several features reminiscent of the US criminal justice system, such as plea bargaining, a trial with a binary verdict corresponding to acquittal and conviction, and a conviction threshold based on the likelihood of guilt of the defendant

·         The commitment assumption needed to perform the mechanism design analysis also find some incarnation in existing features of criminal justice system

 

Collective Commitment with Christian Roessler and Sandro Shelegia, Journal of Political Economy, February 2018

·         Dynamic political equilibria are often inefficient. Can agents collectively commit at the outset to a better policy?

·         Under a power consistency condition, we find that a dynamic equilibrium is dominated by commitment to another long-term policy if and only if the agents exhibit a preference cycle among all long-term policies

·         Power consistency relates the power structure in the dynamic game to the one used to compare long-term policies. It holds if the majority rule is used for all comparisons, but is violated when agents are time inconsistent

·         Imposing restrictions on the policies considered, such as anonymity, may address the indeterminacy predicted by our result

 

Contract Negotiation and the Coase Conjecture, Econometrica, March 2017

·         Actual negotiations contain a puzzle: parties try to withhold private information until striking a deal, but the timing and nature of the agreement can reveal some of this private information and, hence, reveal further gains from negotiations

·         This paper provides a dynamic resolution of the puzzle, which delivers a strategic foundation for renegotiation-proof contracts and extends the analysis of the Coase conjecture (but not the conjecture itself) to richer contractual environments

·         All equilibria converge to the same efficient contracts as negotiation frictions vanish, which only depend on the initial relationship between parties and are straightforward to characterize graphically

 

Supplement

 

A Theory of Intergenerational Altruism with Simone Galperti, Econometrica, July 2017

·         Intergenerational altruism drives any assessment for the long-term consequences of our actions, but what principles underlie such altruism?

·         We axiomatize altruistic preferences such that a generation directly cares about all future generations, and cares about their whole well-being rather than how much they consume

·         This yields a tractable class of altruistic preferences which includes the beta-delta discounting model as particular case, but also models in which the discount factor between two periods depends on consumption at other periods

·         Although these preferences always exhibit present bias, we find that a social planner aggregating the altruistic preferences of all generations may be time consistent

The Hidden Cost of Direct Democracy: How Ballot Initiatives Affect Politicians’ Selection and Incentives with Carlo Prato, Journal of Theoretical Politics, July 2017

·         Direct democracy is often compared to representative democracy. But in modern regimes, these two types of democracies coexist. How do citizen initiatives and referendums affect regimes which are otherwise governed by elected representatives?

·         We identify several equilibrium effects, showing that direct democracy institutions can reduce the quality of selection and incentives of elected officials, sometimes reducing welfare even when these institutions do not entail any administrative or other exogenous cost

 

Social Experimentation with Interdependent and Expanding Technologies with Umberto Garfagnini, Review of Economic Studies, October 2016

·         Experimentation with correlated bandits is well-known to be intractable, and yet it captures many real-life technological environments

·         We analyze experimentation by overlapping generations. Payoffs are determined by the path of a Brownian motion and, hence, correlated

·         “Radical” experimentation means going beyond the farthest known technology and incurs a specific “expansion” cost. It is eventually abandoned with probability 1 for all parameters of our model, leading to stagnation and convergence to a single technological standard

 

Beyond Correlation: Measuring Interdependence through Complementarities with Margaret Meyer

·         Correlation is not an economically-grounded measure of interdependence of random variables, just as variance fails to capture risk except in quadratic or Gaussian cases

·         Interdependence often matters to economists because of complementarities (i.e., supermodularity) in the objective functions they analyze

·         We study this supermodular ordering of interdependence, providing characterizations and concrete methods for comparing distributions, including those distributions generated by common and idiosyncratic shocks
