Executives in parliamentary government

The literature on executive government in parliamentary systems can often be more fun to read because it is not written by political scientists. There are the popular biographies of individual prime ministers with varying degrees of lurid detail abo lit their private lives. There are psycho-biographies probing childhood and other formative experiences. There are the journalists recording the comings and goings of OUf leaders, with an eye for a story that is never discomforted by an inconvenient fact. 1bere are novels. But where afe the theories, the models, and the typologies of exetutive government in parliamentary systems that distinguish political scientists from their more racy rivals? In fact, the academic political science literature is limited-more so than readers might expect or the importance of the subject warrants.
