People may use one of six common methods to reduce inequity.
First, we may change our own inputs.
Second, we may change our own outcomes.
A third, more complex response is to alter our perceptions of ourselves and our behavior.
Fourth, we may alter our perception of the comparison-other’s inputs or outcomes.
Fifth, we may change the object of comparison.
Finally, as a last resort, we may simply leave the situation.
3. Evaluation and Implications
Findings support the predictions of equity theory quite consistently, especially when the
worker feels underpaid.
Most studies appear to uphold the basic premises of the theory. One interesting new twist
on equity theory suggests that some people are more sensitive than others to perceptions of
inequity.
For managers, the most important implication of equity theory concerns organizational
rewards and reward systems.
Equity theory offers managers three messages. First, everyone in the organization needs to
understand the basis for rewards.
Second, people tend to take a multifaceted view of their rewards; they perceive and
experience a variety of rewards, some tangible and others intangible.
Finally, people base their actions on their perceptions of reality.
B. The Expectancy Theory of Motivation
Expectancy theory suggests that people are motivated by how much they want something and
the likelihood they perceive of getting it, also known as VIE theory.
1. The Basic Expectancy Model
Victor Vroom is generally credited with first applying the theory to motivation in the
workplace.
The basic premise of expectancy theory is that motivation depends on how much we want
something and how likely we think we are to get it.
Figure 5.5 summarizes the basic expectancy model. The model’s general components are
effort (the result of motivated behavior), performance, and outcomes. Expectancy theory
emphasizes the linkages among these elements, which are described in terms of
expectancies, instrumentalities, and valences.
2. Effort-to-Performance Expectancy
Effort-to-performance expectancy is a person’s perception of the probability that effort
will lead to successful performance.
If we believe our effort will lead to higher performance, this expectancy approaches a
probability of 1.0. If we believe our performance will be the same no matter how much
effort we make, our expectancy is very low, as low as 0.
