Washed Out by the Crowd? Accountability under Sequential Review

When an early information producer is judged only after others have reviewed and revised the work, the same review that sharpens the final decision can blur the question of who deserves the credit. This paper asks how an organization can still reward careful early work once a chain of later reviewers has acted on it. In the model, an analyst's hidden effort makes an initial report more likely to be right; a sequence of reviewers then reacts to it; and the organization can pay only on the record this process leaves behind. The main result splits the value of any such record into two parts: how much effort improved the first report, and how well the final record still indicates whether the first report was accurate. When later reviewers can overturn a flawed report, review improves decisions but washes the analyst's effort out of the final outcome; therefore, rewarding the final outcome stops working, while rewarding agreement between the first and last word has incentive value instead. When the first report is simply copied by downstream reviewers, the reverse holds. Which reward is better comes down to one thing: how likely the review process is to repair an initial mistake.

Aspiration-Weighted Influence

We study directed social influence when an influencer chooses from a richer menu than a constrained follower (decision maker, the DM). The DM selects from a feasible set, while the influencer displays a distribution over a superset that includes infeasible alternatives. We propose the Aspiration-Weighted Luce Model (AWLM): the DM forms a convex combination of her idiosyncratic Luce preferences within the feasible set and the influencer's distribution, then renormalizes this attempt target onto the feasible set. This renormalization generates an aspirational dampening effect: holding the influencer's within-feasible composition fixed and shifting exposure toward infeasible alternatives attenuates influence on feasible choices. We provide an axiomatic characterization based on proportional responses to shifts in feasible exposure and a unit-slope leverage restriction across different levels of feasible share. The model allows for point identification of influence strength and idiosyncratic preferences from two exposure regimes, yielding testable overidentifying restrictions for empirical application.

Haves and Have-Nots: A Theory of Economic Sufficientarianism

We introduce a generalization of the concept of sufficientarianism, intended to rank allocations involving multiple consumption goods. In ranking allocations of goods for a fixed society of agents, sufficientarianism posits that allocations are compared according to the number of individuals whose consumption is deemed sufficient. We base our analysis on a novel ethical concept, which we term sufficientarian judgment. Sufficientarian judgment asserts that if in starting from an allocation in which all agents have identical consumption, a change in one agent's consumption hurts society, then there is no change in any other agent's consumption which could subsequently benefit society. Sufficientarianism is shown to be equivalent to sufficientarian judgment, symmetry, and separability. We investigate our axioms in an abstract environment, and in specific economic environments. Finally, we argue formally that sufficientarian judgment is closely related to the leximin principle.
