Abstract
This study experimentally explores public good production levels, and the endogenous formation of network structures to facilitate output sharing, among agents with homogenous production costs and valuations. This study is an complementary study of "ENDOGENOUS NETWORK FORMATION IN LOCAL PUBLIC GOODS:
AN EXPERIMENTAL ANALYSIS" in which we studied agents with heterogeneous production costs or valuations in the same decision context.

Experimental Design

Experimental Design
Lab experiment. Participants work as a group. The group size is 6. Each participant will be assigned one of the six roles (labelled from A to F). Each participant needs to act in that assigned role and collect experimental units. They can collect by producing by themselves or exchange with other participants by initiating costly links. Roles have the same ability to produce and initiate links but have different labels. Participants play the game for 20 rounds. At the beginning of each round, their role will be shuffled and assigned.
Experimental Design Details
Randomization Method
By a computer. Participants are randomly assigned into one of the 6 treatments, and randomly assigned into one of the two groups in each treatment.
Randomization Unit
By a computer. Participants are randomly assigned into one of the 6 treatments, and randomly assigned into one of the two groups in each treatment.
Was the treatment clustered?
No
