Forms of Interaction in Social Dilemmas
2-person repeated PDN-person PD

Strategizing in repeated PD games Consider two individuals
who interact repeatedly over time
1) No mechanisms for enforceable commitments.
2) No way to be sure what the other will do on each ‘turn’.
3) No way to eliminate the other player or leave the interaction.
4) No way to change the other player’s payoffs.
What strategy might you use if you had to play this game over and over again with others?
Always Cooperate?
Always Defect?
Something more complicated, perhaps using past behavior?

Group Size and Collective Goods
The group size effect should be reversed if the value of the good does not decrease as individuals consume it (Marwell and Oliver 1993)

Information as a Public Good
1) Information can be consumed by many without losing value (Jointness of Supply or Non-Rival Goods)
2) When information is transferred or exchanged, this can often be done in replication.

Replication
‘Replication’ is not synonymous with jointness of supply or rival/non-rival goods.

Digital Goods
“digital goods” significantly change the economics of exchange
– including situations in which they are produced as a public good.

Producing ‘Impossible Goods’: Thinking About Classifying Information Pools
Order The process of production
and exchange is well-defined and the outcome product is clearly specified
Coordination The roles of the various
actors are clearly specified.
