Abstract
Purpose
The purpose of this paper is to focus on conditional cooperation and investigate whether the difference in contributions between Partners and Strangers designs in linear public goods experiments can be explained by differences in beliefs.
Design/methodology/approach
The author conducted linear public goods experiments by using Partners and Strangers designs with belief eliciting their group member’s contributions.
Findings
The author shows that the difference in the magnitude of the responsiveness of contribution to belief (i.e. the marginal contribution to belief) creates different contribution levels in Partners and Strangers designs.
Research limitations/implications
The presented results imply that having a strategic motive increases contributions by increasing the magnitude of the responsiveness of contribution to belief rather than by raising belief level.
Originality/value
The main claim of this paper is that “marginal contribution to belief” rather than “belief level” causes the difference in contribution levels between Partners and Strangers. This is the first proven evidence of a difference in belief between Partners and Strangers.
