Availability of public goods shapes the evolution of competing metabolic strategies.
Tradeoffs provide a rationale for the outcome of natural selection. A prominent example is the negative correlation between the growth rate and the biomass yield in unicellular organisms. This tradeoff leads to a dilemma, where the optimization of growth rate is advantageous for an individual, whereas the optimization of the biomass yield would be advantageous for a population. High-rate strate...
متن کاملWHY FREE RIDE? Strategies and Learning in Public Goods Experiments
The free riding hypothesis has been the subject of laboratory experiments for more than a decade. While the extent of free riding has often varied across experiments, three observations are consistently replicated. First, there is no significant evidence of free riding in single-shot games. Marwell and Ames (1981) for instance, found that subjects generally provide the public good at levels hal...
متن کاملPublic Health and Public Goods
It has become increasingly difficult to distinguish public health (and public health ethics) from tangentially related fields like social work. I argue that we should reclaim the more traditional conception of public health as the provision of health-related public goods. The public goods account has the advantage of establishing a relatively clear and distinctive mission for public health. It ...
متن کاملZero-Determinant Strategies in Iterated Public Goods Game
Recently, Press and Dyson have proposed a new class of probabilistic and conditional strategies for the two-player iterated Prisoner's Dilemma, so-called zero-determinant strategies. A player adopting zero-determinant strategies is able to pin the expected payoff of the opponents or to enforce a linear relationship between his own payoff and the opponents' payoff, in a unilateral way. This pape...
متن کاملCompetition of tolerant strategies in the spatial public goods game
Tolerance implies enduring trying circumstances with a fair and objective attitude. To determine whether evolutionary advantagesmight be stemming fromdiverse levels of tolerance in a population, we study a spatial public goods game, where in addition to cooperators, defectors, and loners, tolerant players are also present. Depending on the number of defectors within a group, a tolerant player c...
