In various animal taxa, prior experience of contests influences the consequences subsequent contests. A well-known example is winner and loser effects, in which winners have a higher winning probability, whereas losers become more likely to lose Previous studies suggested that intensity past also affects future probability two ways: modulating extent winner–loser effect or decreasing both loser...

Background. There is a weakness that the win-loss ranking model in the MLB now is calculated based on the result of a win-loss game, so we assume that a ranking system considering the opponent’s team performance is necessary. Objectives. This study aims to suggest the PageRank algorithm to complement the problem with ranking calculated with winning ratio in calculating team ranking of US MLB. ...

We consider concurrent games played by two-players on a finite-state graph, where in every round the players simultaneously choose a move, and the current state along with the joint moves determine the successor state. We study the most fundamental objective for concurrent games, namely, mean-payoff or limit-average objective, where a reward is associated to each transition, and the goal of pla...

We study the effect of lottery wins on strength social ties and its different types, including support networks, in United Kingdom. On average, we find that winning more increases probability meeting friends most days, which is consistent with complementary income ties. The opposite true regards to held for instrumental reasons such as talking neighbours. Winning also lessens an individual netw...

Does Subjective Evaluation of Probability Impact Asset Prices? The Nobel Prize–winning capital asset pricing model (CAPM) predicts that expected excess return any is positively proportional to its exposure the overall market: beta, leading an upward-sloping security market line. However, this prediction contradicted by empirical studies return–beta slope often flat or even downward-sloping, a p...

The Hat Game (Ebert’s Hat Problem) got much attention in the beginning of this century; not in the last place by its connections to coding theory and computer science. This paper studies Ebert’s hat problem with three persons and three colors, where the probabilities of the colors may be different (asymmetric case) . All players guess simultaneously the color of their own hat observing only the...

This study examined the effects of manipulating the size of groups of male student negotiators and their ability to communicate with one another in a game in which one player held veto power (i.e., had to be included in any winning coalition). The predictions of three models, the core, the value, and the weighted probability model, were tested. The game, in which the veto player could form a wi...
