Equity theory is an extension of social exchange theory in that people strive to achieve fairness in their relationship in terms of social exchange
According to this theory any kind of inequity will lead to distress in the relationship
This applies to those who put too much into a relationship as well as those who take too much.
The greater the inequity, the greater the dissatisfaction, leading to increased distress
ratio of inputs and outputs
Equity does not necessarily mean equality
It is possible for a partner to both give and receive different amounts and still judge the relationship to be fair.
The ratio of input/output is what matters.
E.g. lf you put in less but get less out of the relationship that is considered fair/equitable
When there is any perceived inequity people are also motivated to restore it.
evaluation - supporting research
Stafford and Canary (2006) Asked 200 married couples to complete a questionnaire on relationship equity and satisfaction.
Satisfaction was highest for those who perceived their relationship as equitable, followed by over benefitted partners, and lowest for under benefitted partners
When asked about specific maintenance strategies, lower benefitted partners reported a distinct lack of the essential strategies.
further evaluation
In addition, Joel et al. (2020) found that two of the top five predictors of relationship success were 'perceived partner commitment" and 'perceived partner satisfaction'
This suggests that we want to maximise both our partner's inputs and outputs in a relationship
This fits with the predictions of equity theory
methodological difficulties with measuring benefits and costs in equity theory
Rewards and costs are difficult to quantify.
They can be entirely subjective and emotional
They have often been defined superficially in order to measure them e.g. money
This makes it very difficult to accurately quantify whether benefits might outweigh costs or not
BECAUSE OF THIS...
Clark and Mills (2011) suggest that the theory may work better for relationships where it is easier to 'keep score'
Exchange relationships (coworkers) may involve equity, but Communal relationships (romantic partners) are less likely to.
Equity theory may therefore not be generalisable to all types of relationships
