Attiat Ott and Richard Cebula have recognised the need to present, in an accessible and straightforward way, the voluminous literature in the public economics arena. Advances in econometric techniques and the spillover of knowledge from other disciplines made it difficult, not only for students but also for lecturers, to accurately find the information they need. This major new Companion addresses a wealth of topics common to the study of both public economics and public choice including questions such as: How does one structure the whole spectrum of public finance in a manageable framework? What is Wagner#s Law really about and what does empirical testing tell us? How binding is the budget constraint? How encompassing is a dictator#s interest? How do veto powers of the executive, institutional structures and regimes affect public sector outcomes? Do voters behave rationally? Do conflicts yield benefits? Is war cost effective and does secession offer a viable exit option?
