Enforcing Cooperation in Networked Societies
Which social norms and networks maximize cooperation in bilateral relationships? We study a network of players in which each link is a repeated bilateral partnership with two-sided moral hazard. The obstacle to community enforcement is that each player observes the behavior of her partners in their partnerships with her, but not how they behave in other partnerships. We introduce a new metric f...
متن کاملThe social amoebae.
Noted biologist and author John Tyler Bonner has experimented with cellular slime molds for more than sixty years, and he has done more than anyone else to raise these peculiar collections of amoebae from a minor biological curiosity to a major model organism--one that is widely studied for clues to the development and evolution of all living things. Now, five decades after he published his fir...
متن کاملThe Cold War of the Social Amoebae
When confronted with starvation, the amoebae of Dictyostelium discoideum initiate a developmental process that begins with cell aggregation and ends with a ball of spores supported on a stalk. Spores live and stalk cells die. Because the multicellular organism is produced by cell aggregation and not by growth and division of a single cell, genetically diverse amoebae may enter an aggregate and,...
متن کاملSelf-Enforcing Cooperation with Graduated Punishments∗
Case studies of self-enforcing cooperation in repeated interactions usually find that the punishments inflicted on deviators are mild to start with, and increase only if there is evidence of persistent deviation. We model this using a combination of imperfect monitoring and asymmetric information in a one-sided prisoner’s dilemma. Call the player with the temptation to cheat player B, and the o...
متن کاملGenome Analysis of Social Amoebae
Genomics is now an indispensible part of the biological sciences. Today a species description without genome information is incomplete. This chapter describes the current knowledge on the genome of the model species Dictyostelium discoideum. A comparison with other social amoebae genomes covering the whole breadth of this branch of evolution carves out driving forces of speciation and the commo...
