the nature and quality of social exchange and close bonds. It suggests that once the individuals start to give more of their resources to one another, relationships evolve progressively from exchanging superficial goods to other, more meaningful exchanges. It progresses to the point called “self-disclosure”, where the individuals share innermost thoughts and feelings with one another. Equity and inequity In this process, the individuals will compare their rewards with others’ in relation to their costs. Equity can be defined as the balance between a person's inputs and outcomes on the job. Some examples of inputs can be qualifications, promotions, interest on the job and how hard one works. Some outcomes can be pay, fringe benefits, and power status. The individual will mainly expect an equitable input-outcome ratio. Inequity happens when the individual perceives an unbalanced ratio of their outcomes and other's outcomes. This can occur in a direct exchange of the two parties, or there can be a third party involved. An individual's point of view of equity or inequity can differ depending on the individual. Aging The basis of social exchange theory is to explain social change and stability as a process of negotiating exchanges between parties. These changes can occur over a person's life course through the various relationships, opportunities, and means of support. An example of this is the convoy model of support, this model uses concentric circles to describe relationships around an individual with the strongest relationships in the closet circle. As a person ages, these relationships form a convoy that moves along with the person and exchanges in support and assistance through different circumstances that occur. It also changes through the directionality of support given to and by the individual with the people within their support network. Within this model, there are different types of support (Social support) a person can receive, those being intangible, tangible, instrumental, and informational. Intangible support can either be social or emotional and can be love, friendship and appreciation that comes with valuable relationships. Tangible support are physical gifts given to someone such as land, gifts, money, transportation, food, and completing chores. Instrumental support are services given to someone in a relationship. Finally, informational support is the delivering of information that is helpful to an individual. Theoretical propositions Ivan Nye came up with twelve theoretical propositions that aid in understanding the exchange theory. Rewards being equal, they choose alternatives from
