Although dogs are used by subsistence hunters in many locations throughout the world, hunters with dogs have not been studied from an optimal foraging perspective. A study of indigenous Mayangna and Miskito hunters in Nicaragua indicates that the use of dogs affects both the encounter rates and the pursuit times of several prey types. Before hunters can identify the prey type and initiate a pur...

We introduce and analyze an inter-temporal choice model where customer valuations are uncertain and evolve over time. The model leads directly to the study of call options on capacity that are similar to partially refundable fares. We show that the capacity provider earns significantly higher revenues by selling real options on capacity than low-to-high pricing. We also investigate the social i...

A basic problem in empirical economics involves using data from one domain to make out-of-sample predictions for a different, but related environment. When the choice data are binary, a canonical method for making these types of predictions is the logistic choice model. We investigate if it is possible to improve out-of-sample predictions by changing two aspects of the canonical approach: 1) Us...

Segal and Spaeth’s The Supreme Court and the Attitudinal Model Revisisted argues that judges are policymakers who decide cases primarily (and sometimes exclusively) on the basis of their personal policy preferences. This is particularly true of Supreme Court justices, for the American political system leaves them unconstrained when issuing decisions on the merits. Segal and Spaeth label this th...

D choice models are appealing for airline revenue management (RM) because they offer a means to profitably exploit preferences for attributes such as time of day, routing, brand, and price. They are also good at modeling demand for unrestricted fare class structures, which are widespread throughout the industry. However, there is little empirical research on the practicality and effectiveness o...

The class of maximin actions in general decision problems is characterized. JEL classification: C70, D81.

There is wide theoretical coverage of sophisticated voting despite a clear empirical gap. There are only a handful empirical examples of sophisticated voting which are documented. There is also no systematic searching approach to recover such cases. This paper offers the first systematic approach to identify votes where sophisticated voting seems likely. The algorithm developed here cannot stat...

Following Barberà, Sonnenschein, and Zhou (1991, Econometrica 59, 595-609), we study rules (or social choice functions) through which agents select a subset from a set of objects. We investigate domains on which there exist nontrivial strategy-proof rules. We establish that the set of separable preferences is a maximal domain for the existence of rules satisfying strategyproofness and no-vetoer.

Economists tend to adopt an empiricist approach to poverty, commonly calculating it as the proportion of the population that fall below some speci®ed income threshold. This approach has been developed to take into account heterogeneous household needs by using income equivalence scales, but most other individual characteristics are totally ignored. This paper questions the relevance of this app...
