Offers beyond the negotiating dyad: Including the excluded in a network exchange experiment

More Satisfaction, Less Equality: Distributive Effects of Transparent Needs in a Laboratory Experiment

Societies are confronted with the dilemma that need satisfaction requires transparent individual needs. We study the effect of information about others' needs on the distribution of a joint endowment in a three-player network exchange game in a laboratory experiment. Need levels are exogenously given and either transparent (known to all three network members) or opaque (only known to the players themselves). The three players negotiate in dyads until two players agree on a distribution. We expect that the transparency of need thresholds raises need satisfaction but lowers equality. The results suggest that the members of the dyad who agree on the distribution can satisfy their own need thresholds even when information about thresholds is opaque. The effect of transparency on the remaining network member is antithetical: while transparency increases the rate of need satisfaction, it decreases the average share of allocations when needs are low. In the opaque condition, allocated shares are larger, but need satisfaction is lower. This reveals the ambivalent distributive effects of transparent need thresholds: Transparency helps those with the highest need thresholds, but it can hurt those with lower need thresholds, and it barely affects the ones with the most influence on the decision.

Beyond Dyads and Triads: A Comparison of Tetrads in Twenty Social Networks

Social psychologists focus on the microlevel features that define interaction, often attending to dyads and triads. We argue that there also is utility in studying how configurations of four actors, or tetrads, pattern our social world. The current project considers the prevalence of directed tetrads across twenty social networks representing five relationship types (friendship, legislative co-sponsorship, Twitter, advice seeking, and email). By comparing these observed networks to randomly generated conditional networks, we identify tetrads that occur more frequently than expected, or network motifs. In all twenty networks, we find evidence for six tetrad motifs that collectively highlight tendencies toward hierarchy, clustering, and bridging in social interaction. Variations across network genres also emerge, suggesting that unique tetrad structural signatures could define different types of interaction.

The impact of need on distributive decisions: Experimental evidence on anchor effects of exogenous thresholds in the laboratory

Giving more to those who need more has an intuitive appeal for determining the just allocation of resources. The need principle is considered one of the three major principles of distributive justice. In contrast to equality or equity, however, evidence on the adherence to the needs principle rests mainly on stated instead of revealed preferences. In this paper we present an experimental design that exogenously assigns objective, heterogeneous need thresholds to individuals in small laboratory societies structured by a three-line network. The data reveal that a large proportion of individuals respond to others’ need thresholds, but at a declining rate as thresholds increase. The equal distribution marks a discrete drop in the need satisfaction rate: Need thresholds above the equal distribution are less frequently satisfied. We conclude that others’ needs are weighed against self-interest and equality. Our results provide evidence that distributions may be socially justified on grounds of the need principle.
