The group and exchange theories of leadership are derived from social psychology. These have their roots in the exchange theory. Leaders from different kinds of relationships with various groups of subordinates. Group theories describe how leaders need to maintain their position in group dynamics.
Social exchange theory proposes that social behavior is the result of an exchange process. The purpose of this exchange is to maximize benefits and minimize costs. Social Exchange Theory is a social psychological and sociological perspective that explains social change and stability as a process of negotiated exchanges between parties. Social Exchange Theory posits that all human relationships are formed by the use of a subjective cost-benefit analysis and the comparison of alternatives.
Costs are the elements of relational life that have negative value to a person, like time, money, effort etc. and on the other hand rewards are the elements of a relationship that have positive value like sense of acceptance, support, and companionship etc. The Social Exchange perspective argues that people calculate the overall worth of a particular relationship by subtracting its costs from the rewards it provides. If worth is a positive number, it is positive relationship. On the contrary, negative number indicates a negative relationship. The worth of a relationship influences its outcome, or whether people will continue with a relationship or terminate it. Positive relationships are expected to endure, whereas negative relationships will probably terminate.
Social exchange theory can also be applied to leadership studies as reported by Hollandder and Julian (1969). They propose that the leader provides more benefits or regards than burden or costs to the followers who in exchange help him achieve the goals of the organization. There must be a positive exchange between the leader and followers in order for group goals to be accomplished. According to this group of theories, a leader provides more benefits/rewards than burdens/costs for followers.
In a group, members make contributions at a cost to themselves and receive benefits at a cost to the group or other members. The leader can give rewards to his followers in the form of appreciation or monetary increments or promotion for accomplishment of the organizational goals or tasks. These rewards have positive impact on attitudes, satisfaction and performance of the followers.
In return of these awards, followers respect the leader and give him due regard for his status and esteem and believe in his heightened influence. The leader tends to follow initiating structure when followers do not perform very well and increases his emphasis on consideration when the followers do a good job.
In this balancing act, the perception of his followers of his being an effective leader increases and this equation is mutually beneficial for both the leader and the follower. Interaction continues because members find the social exchange mutually rewarding.
Substitutes for leadership theory is based on understanding the context within which leadership occurs. Different situational factors can enhance, neutralize, or substitute for leader behaviors like under certain circumstances, situational factors may substitute for leadership. These substitutes are of two types - substitutes and neutralizers. Substitutes take away from the leader's power and help group members increase their performance. Neutralizers only remove influence from the leader.
Management theories are the recommended management strategies that enable us to better understand and approach management. Many management frameworks and guidelines were developed during the last four decades.
University of Iowa Studies was the first leadership study to analyze leadership using scientific methodology. The study was conducted by Lewin, Lippitt, and White and worked on different styles of leadership. The studies explored three leadership styles - authoritarian, democratic, and laissez-fair leaders. This early study was very influential and established three major leadership styles.
According to the three-skill approach of Katz, the individual's leadership abilities vary depending on where leaders are in a management hierarchy. The practical implication of skills approach to leadership is that leaders can improve their capabilities in leadership skills through training and experience.
Trait Theory of Leadership is based on the assumption that people are born with inherited traits and some traits are particularly suited to leadership. The theory aims to discover specific leadership & personality traits and characteristics proven to predict the likelihood of success or failure of a leader.
The Hersey and Blanchard Situational Theory model suggests that a leader must adapt his leadership style based on task and relationship behaviors appropriate to the situation. Leadership style is dependent on the maturity level and abilities of followers. Under this model, successful leadership is both task-relevant and relationship-relevant.
Normative leadership theories are built on moral principles and tell leaders how they ought to act. Victor Vroom formulated the normative model of leadership that specifically address leader behavior explicitly built on moral principles or norms. Normative leadership theories tell leaders how they should act to raise the moral performance inside the working group and manage their different responsibilities.
Attribution Theory of Leadership
The attribution theory of leadership deals with the formation of individual opinions about the reasons for particular events or observations. People will always try to understand why people do what they do. The leader will make a judgment about his employees based on his attribution of the causes of the employees' performance. Individuals will also make inferences about the leader and react to poor performance by the leader.
Contingency Theories of Leadership
Contingency theories of leadership focus on both the leader's persona as well as the situation/environment in which that leader operates. These theories consider the context of leadership which means whether or not the leadership style suits a particular situation and states that a leader can be effective in one circumstance and a failure in another one. A leader will be most effective when he applies the right leadership style to a given situation and environment around him. Contingent leaders are flexible and adaptable.
The skills approach to leadership suggests that certain skills are important for effective leadership. Skills are what leaders can learn and develop, whereas traits are innate characteristics. The main skills needed for leadership, according to one such theory, are technical, human, and conceptual.
