RECENT PAPERS

 

Improving Criminal Trials by Reflecting Residual Doubt: Multiple Verdicts and Plea Bargains with Ron Siegel

·       Adding a third verdict to the trial system raises welfare without increasing the risk of punishing the innocent or the incentives to commit a crime, and has a simple implementation

·       However, plea bargaining with just two verdicts has more informational value than any multi-verdict system, and is in fact the optimal mechanism

·       Adding a third verdict can increase incentives to acquire information

 

Social Experimentation with Interdependent and Expanding Technologies with Umberto Garfagnini, accepted in the Review of Economic Studies

·       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

 

A Theory of Intergenerational Altruism with Simone Galperti, R&R, Econometrica

·       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

 

Contract Negotiation and the Coase Conjecture R&R, Econometrica

·       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 contracts as negotiation frictions vanish, which are straightforward to characterize graphically

 

Collective Commitment with Christian Roessler and Sandro Shelegia, R&R, Journal of Political Economy

·       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

 

Explicit Renegotiation in Repeated Games with Mikhail Safronov

·       Cooperation in repeated games relies on the threat of a punishment phase. Is cooperation still feasible when this punishment can be renegotiated?

·       We introduce an explicit protocol of renegotiation. Players may propose new plans, which specify future actions, future proposals, and players’ reactions to these proposals. A player who rejects a proposal may be rewarded for “enforcing the social norm”

·       The set of renegotiation-proof equilibria has a simple graphical characterization

 

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

 

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

·       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
