We propose an approach to help resolve the “battle royale” between the information retrieval and information science communities. The information retrieval side favors the Cranfield paradigm of batch evaluation, criticized by the information science side for its neglect of the user. The information science side favors user studies, criticized by the information retrieval side for their scale an...

This paper incorporates two-sided moral hazard in an otherwise frictionless matching market for partnerships and examines how unobservability of the effort choices of the matched partners impacts the equilibrium sorting patterns. We find that the direction of this impact depends on whether unobservable effort and observable type are complements or substitutes: when they are complements (i.e.mar...

The Adams apportionment method is the only divisor method that consistently favors small districts relative to the Hamilton method. The Jefferson method is the only divisor method that favors large districts relative to the Hamilton method. These statements hold for the Balinski and Young [3] interpretation of "favoring small/large districts," and for the partial "majorization ranking" introduc...

Impulsivity is a stable personality trait associated with myopic choice behavior that favors immediate rewards over larger, delayed rewards and is often characterized as maladaptive inside and outside of the laboratory. An alternative view suggests that the consequences of trait impulsivity depend on the nature of the task environment. On this view, the optimal level of impulsivity varies acros...
