Constitutional Reform, Change of the System and Choices Maximizing Social Utility Function

The paper provides a critical analysis of J. Buchanan’s project of constitutional political economy. It is considered in order to make sense of the present-day political and social crisis in Bulgaria. This innovative project for liberalism proposes a more adequate version of the contractual theory through constitutional rules that determine the rational construction of the state and the common life of the people. They choose to obey these rules, guided by the idea of maximizing the social function of benefit. In the search of a path to social change in Bulgaria, we can learn from the conservative elements in the conception of Buchanan and his followers.
