This assumption implies that W(A)=11 and W(S =5, so altruism evolves.
Note also that, by the symmetry of the problem, this assumption implies (phi=0).
This assumption implies that those who would see the offender frequently are likely to recognize him.
This assumption implies, and is obtained for in (24) as (25).
This assumption implies that each node i probes the medium at instants of a Poisson clock with rate r i.
This assumption implies that a good bond exists between fiber and resin to prevent slippage between them and to prevent wrinkling of the fiber.
This assumption implies that the w-nullcline is a graph ({w=psi _{lambda} v)}), and (psi_{lambda}) is a monotonically increasing function.
This assumption implies that our study observes (and controls for) all of the variables that simultaneously influence both treatment assignment and potential outcome.
This assumption implies that our selection on observables is capable of controlling for the sources of self-selection into educational tracks.
This assumption implies that the series (sum_{i=1}^{infty}sigma(i xi(i+1)) converges almost surely (see, e.g., [17], page 384, or Lemma 4 below).
This assumption implies, for example, that all consumers would prefer shopping at Eroski or El Corte Inglés than at Auchan if prices were identical across supermarket chains.
