Given the low general fitness of the I cells (with γ=0.8), it is not surprising that they quickly become extinct as the advantage of cooperation sustains, and promotes D and S cells in the tumour.
"Can that cooperation be sustained if we have these other disputes?" he asked.
When that same incentive is implemented publicly, however, cooperation is sustained at significantly higher rates than in either the baseline or private punishment treatments.
It measure how cooperation is sustained for households.
This limited level of cooperation is sustained by both direct and indirect reciprocity.
On the other hand, in the RRG on the WS networks with (p=0.01), (r^a) increased when (T_{rm{W}}=2, 3), and 4 and cooperation was sustained by both mutual and one-sided reciprocal agents (Fig. 14b).
The characteristic that distinguishes the WS networks from the complete graphs is the ratio of (r^m)–(r^a): Table 3 indicates that cooperation was sustained by mostly mutual reciprocal relationships in RRG (0.8, 0.1) and RRG (1.0, 0.1) on the complete graphs, but in the RRG on the WS network with (p=0.01), it was sustained by both types of reciprocal relationship.
Shifter holds a similar view but with a caveat: "Perhaps some general principles apply, such as: to be effective, U.S. cooperation requires sustained engagement and needs to be wide-ranging and bipartisan.
Following the metaphor outlined above, we can interpret our result in the light that Conditions 1 and 2 share the feature that the leader is rewarded, while Conditions 2 and 3 share the characteristic that cooperation is sustained by reciprocity.
Here, we use a controlled laboratory experiment to show that cooperation is sustained in a generosity competition with trophy rewards, but breaks down in the same environment with equally valuable but non-unique and non-displayable rewards.
