to the study, the amount one person rewards another and the comparison levels for alternatives become the most important factors in determining liking and satisfaction. Auld, C. and Alan C. conducted a study to discover what processes occur and what is experienced during social leisure relationships. They use the concept of reciprocity to understand their findings. The study concluded that meeting new people is often given as a major reason for participation in leisure activities, and meeting new people may be conceptualized as an exercise of reciprocity. In this case, reciprocity is perceived as a starting mechanism for new social relationships because people are willing to be helped by others, expecting that the help will eventually be returned. A study conducted by Paul, G., called Exchange and access in field work tries to understand the relationships between the researchers and subjects. This study concludes that Bargaining helps to satisfy the more specific needs of the parties because greater risks are taken to obtain more information. This study also introduces the concept of trust (social sciences) to determine the duration of relationships. Interracial marriage Patterns of interracial marriage have been explained using social exchange theory. Kalmijn suggests that ethnic status is offset against educational or financial resources. This process has been used to explain why there are more marriages between black men and white women than between white men and black women. This asymmetry in marriage patterns has been used to support the idea of a racial hierarchy. Lewis, however, explains that the same patterns of marriage can be accounted for in terms of simple facial attractiveness patterns of the different gender by race groupings. Recent changes have seen an increase in black women marrying white men and a decrease in raw prevalence of interracial marriages when it comes to black women. There has also been a shift in the concentration of interracial marriage from mostly being between those with low education levels to those with higher levels of education. Business Social exchange theory has served as a theoretical foundation to explain different situations in business practices. It has contributed to the study of organization-stakeholder relationships and relationship marketing. The investment model proposed by Caryl Rusbult is a useful version of social exchange theory. According to this model, investments serve to stabilize relationships. The greater the nontransferable investments a person has in a given relationship, the more stable the relationship is
