This article develops a theory that explains how and when emotions, produced by social exchange, generate stronger or weaker ties to relations, groups, or networks. It is argued that social exchange produces positive or negative global feelings, which are internally rewarding or punishing. The theory indicates that social units (relations, groups, networks) are perceived as a source of these feelings, contingent on the degree of jointness in the exchange task. The jointness of the task is greatest if (1) actors find it difficult to distinguish their individual effects on or contributions to solving the exchange task (nonseparability) and (2) actors perceive a shared responsibility for success or failure at the exchange task. The theory explicates the effects of different exchange structures on these conditions and, in turn, on cohesion and solidarity. Implications are developed for network-to-group transformations.

The purpose is to incorporate emotions as an explicit, central feature of social exchange processes. The article accomplishes this by (1) conceptualizing individual actors as emoting as well as cognizing, feeling as well as thinking, (2) treating emotions as internal reinforcements or punishments, and (3) Social exchange is conceptualized as a joint activity of two or more actors in which each actor has something the other values. The implicit or explicit task in exchange is to generate benefit for each individual by exchanging behaviors or goods that actors cannot achieve alone (Thibaut and Kelley 1959;Homans 1961;Emerson 1972b). The affect theory of social exchange expands the domain of exchange theorizing in two main ways. First, exchange outcomes-rewards and punishments-are construed as having emotional effects that vary in form and intensity. When exchanges occur successfully, actors experience an emotional uplift (a "high"), and when exchanges do not occur successfully, they experience emotional "downs" (Lawler and Yoon 1996). Mild everyday feelings, therefore, are intertwined with exchange. Positive emotions include e...

This study refines and experimentally tests a theory of relational cohesion that explains how and when actors become committed to one another in the context of multiactor exchange. The theory asserts that frequent social exchange results in (1) positive emotions that solidify and strengthen the person-to-group bond and (2) uncertainty reduction that renders the focal group more salient in relation to others. These two mechanisms produce a sense of psychological group formation and ultimately increase observable acts of commitment. In a "productive exchange" setting, three actors negotiate a joint venture that requires the assent of all members. The exchanges featured two forms of commitment behavior: the giving of small token gifts and the decision to invest in a three-way prisoner's dilemma. The results suggest that positive emotion and uncertainty reduction are theoretically distinct and affect commitment behavior through different mechanisms. The article concludes by discussing the general implications for commitment and social order.

We analyze and review how research on emotion and emotional phenomena can elaborate and improve contemporary social exchange theory. After identifying six approaches from the psychology and sociology of emotion, we illustrate how these ideas bear on the context, process, and outcome of exchange in networks and groups. The paper reviews the current state of the field, develops testable hypotheses for empirical study, and provides specific suggestions for developing links between theories of emotion and theories of exchange.
