 Competition between leaders empowers followers to choose the leaders they prefer.Leadership is a costly activity, and leader can be rewarded in a variety of ways; many form non-profit organizations which attract donations or membership subscriptions.Casson's theory of leadership has an analogy with his theory of entrepreneurship because entrepreneurs establish for-profit organisations (firms) to exploit special knowledge they have developed, which is a technological and factual analogue of the systems of values and beliefs developed and exploited by leaders.
