For matrix games we study how small nonzero probability must be used in optimal strategies. We show that for n × n win-lose-draw games (i.e. (−1, 0, 1) matrix games) nonzero probabilities smaller than n are never needed. We also construct an explicit n × n win-lose game such that the unique optimal strategy uses a nonzero probability as small as n. This is done by constructing an explicit (−1, ...

Several pieces of anatomical, biochemical and pharmacological evidence indicate that the endocannabinoid system via CB1 receptors is implicated in the control of emotional behavior. However, previous studies have reported unclear and contradictory results concerning the role of cannabinoids in anxiety. The aim of the present study was to examine the influence of the cannabinoid agonist WIN 55,2...

Many new product development (NPD) alliances tend to be asymmetric, that is, they are formed between a larger firm and a smaller firm. These asymmetric alliances typically result in changes in the shareholder values of the partner firms. Are the changes in shareholder ...
