Testing Ten Theories

Using the most comprehensive data set now available, this investigation tests the precision of all exchange theories that now contend. Beyond precision, the investigation focuses on broad issues of effectiveness including consistency, parsimony, and whether the theories can be applied to structures larger than normally studied in the lab. Seeking greater parsimony, this investigation introduces a new model by combining parts of two contending theories. We find that all ten theories have scientific merit for all can predict with some effectiveness for the exchange structures experimentally investigated. Nevertheless, the ten vary in precision. Elementary Theory is the most precise. The new Expected-value Resistance model ranks second in precision and is the simplest. Both apply to large networks as well as the best of the other theories.

One-shot exchange networks and the shadow of the future

From the Prisoners Dilemma and other games, it is well known that strategy selection in one-shot games can be very different from that in iterated games. Because exchange structures were studied only as iterated games, whether one-shot structures differ was not known. Nor have exchange theories previously considered whether events in structures would be different if studied as one-shot games. This paper offers new theory to predict one-shot exchange structures and one-shot experiments to test that theory. As predicted, the experiments found that processes and outcomes of one-shot exchange structures are quite different from those of iterated exchange structures. For example, certain relations that are strategically used as threats in iterated exchange structures occur very rarely in one-shot structures. It follows that power differences in one-shot structures regress from those observed for repeated structures.

Abstract Purpose This exposition explains how Elementary Theory works and how it has been developed over the last two-and-a-half decades. Both increased scope and heightened precision are covered. Methodology/Approach Theoretic methodology is explained. Using that method formal models are constructed analogous to empirical events. Those models predict events, design experiments, and guide applications in the field. Findings There is a widely held belief in sociology that theory becomes more vague and imprecise as its scope broadens. Whereas broader generalizations are more vague than narrower ones, this exposition shows that abstract theory becomes more precise as its scope broadens. Research Limitations/Implications Here implications and limitations are closely connected. Regarding implications, this exposition shows that scientific explanations and predictions are viable today in sociology but only when exact theory is employed. Regarding limitations, the theory and research included in this exposition make clear why the empiricist search for regularities that dominates sociological research is so very limited in its results. Originality/Value of Chapter This exposition demonstrates that theory is the method of all the sciences and in particular the science of sociology.
