What political process is most likely to be used when the costs of a policy are concentrated and its
benefits are distributed widely?

majoritarian politics

client politics

interest-group politics

entrepreneurial politics

The correct answer is - entrepreneurial politics.

Explanation:

In the framework of entrepreneurial politics the costs of a policy are shared by a small group of people, often referred to as political entrepreneurs. These people support a given policy, are going to benefit from its implementation, but they also have resources (often financial) to support the process of this policy implementation. Meanwhile, the outcome of the policy is beneficial for the general public as well.  

For example, a group of political entrepreneurs wants to promote the policy for flexible working hours to become a mandatory option for workers of certain industries. They invest funds into research that shows that people have different circadian rhythms and thus the productivity of the labor force would increase if employees have an option for flexible hours.

Political entrepreneurs would benefit from this policy because not only their companies follow flexible hours, but the companies they work with would do as well. This, in turn, would lead to increased productivity and satisfaction from the employees on a larger scale.
