We present two elaborations of the model of Broom and Ruxton that found evolutionarily stable kleptoparasitic strategies for foragers. These elaborations relax the assumption that the distribution of times required to handle discovered food items is exponential. These changes increase the...

The current study examined the economics of cooperation in controlled-payoff games by using captive blue jays, Cyanocitta cristata. This investigation used a special feeding apparatus to test for the stability of cooperative choice in a series of iterated games. The jays experienced...

Models of biparental care predict that parents should compensate incompletely for any change in their partner's investment. Experimental tests have, however, yielded results that range from full compensation, through a lack of any reaction, to a matching response. Here we suggest a new, adaptive...

For decades, evolutionary biologists and anthropologists have puzzled over the negative relationship that exists between wealth and fertility in humans. Particularly mystifying have been that (1) humans do not appear to translate their reproductive resources into additional offspring, and (2)...

We propose a new, evolutionary, game-theoretic model of conditional human mating strategies that integrates currently disconnected bodies of data into a single mathematically-explicit theory of human mating transactions. The model focuses on the problem of how much resource a male must provide...

In this article, we generalize the position value, defined by Meessen (1988) for the class of deterministic communication situations, to the class of generalized probabilistic communication situations (G´omez et al. (2008)). We provide two characterizations of this new allocation rule....

In this note we review some known minimax theorems with applications in game theory and show that these results form an equivalent chain which includes the strong separation result in finite dimensional spaces between two disjoint closed convex sets of which one is compact. By simplifying the...

This paper investigates the relationship between market share and promotional expenditures the long run. Using data that span a decade and 91 product categories we find that market shares are stationary for a majority of the products in the data base. We find that relative promotional...

This paper offers the generalization that competitive promotions are mixed strategies. First an empirical regularity is established that promotions are independent across competitors. This regularity is then elaborated on in the context of a promotion game. The promotion game is linked to...

This paper examines the use of game theory in educational sciences. It describes the evolution of game theory from the defining axioms of Von Neumann and Morgenstern in 1944 to the present. After the Introduction and this description, the third part presents the methodology used to select...
