Why Interest Groups Form
Introduction
The general theory is that individuals must be enticed with some type of benefit to join an interest group. Known as the free rider problem, it refers to the difficulty of obtaining members of a particular interest group when the benefits are already reaped without membership. For instance, an interest group dedicated to improving farming standards will fight for the general goal of improving farming for every farmer, even those who are not members of that particular interest group. Thus, there is no real incentive to join an interest group and pay dues if the farmer will receive that benefit anyway. Interest groups must receive dues and contributions from its members in order to accomplish its agenda. A collective good refers to something of value that cannot be withheld from a nonmember of a group. To illustrate the free rider problem and collective goods, take environmental groups who advocate for a cleaner environment. While every individual in the world would benefit from a cleaner environment, an environmental protection interest group does not, in turn, receive monetary help from every individual in the world.
Types of Benefits and Incentives
Selective material benefits are benefits that are usually given in monetary benefits. For instance, if an interest group gives a material benefit to their member, they could give them travel discounts, free meals at certain restaurants, or free subscriptions to magazines, newspapers, or journals. Many trade and professional interest groups tend to give these types of benefits to their members. A selective solidary benefit is another type of benefit offered to members or prospective members of an interest group. These incentives involve benefits like socializing congeniality, the sense of group membership and identification, the status resulting from membership, fun and conviviality, the maintenance of social distinctions, and so on. A solidary incentive is one in which the rewards for participation are socially derived and created out of the act of association.
An expressive incentive is another basic type of incentive or benefit offered to being a member of an interest group. People who join an interest group because of expressive benefits likely joined to express an ideological or moral value that they believe in. Some include free speech, civil rights, economic justice, or political equality . To obtain these types of benefits, members would simply pay dues, donating their time or money to get a feeling of satisfaction from expressing a political value. Also, it would not matter if the interest group achieved their goal. These members would merely be able to say they helped out in the process of trying to obtain these goals, which is the expressive incentive that they got in the first place. The types of interest groups that rely on expressive benefits or incentives would be environmental groups and groups who claim to be lobbying for the public interest. A purposive incentive refers to a benefit that comes from serving a cause or principle; people who join because of these are usually passionate about the cause or principle .
