George Bushs 1988 campaign pledge, 'Read my lips: no new taxes,' has become a mantra for those who distrust politicians and bureaucrats. The gulf between what political leaders say and do seems to be widening, and in democratic societies around the world, contributing to an atmosphere of cynicism and apathy among the citizenry. Understanding the characteristics and functions of speech in policy processes is a requirement for trying to overcome this problem; indeed, politicians and bureaucrats spend a good proportion of their time and resources discoursing, i.e., writing, speaking, and publishing. However, there has been scant analysis of political discourse; the aim of this book is to fill this analytical gap, by exploring political speech from a variety of perspectives, including normative, epistemological, and empirical. Incorporating insights from economics, political science, philosophy, and law, and evidence from the United States, Canada, France, Italy, Turkey, and the EU, the book addresses a wide variety of timely issues, including:. Fiscal discipline in speeches vs budget balance: Is an improvement (deterioration) of the budget balance preceded by a more (less) fiscally disciplined discourse? Revenues and spending forecasted in budget speeches vs realised budget outcomes: Is there a systematic bias? If so, how can we explain it? Electoral pledges vs actual realisations: Do governments follow up on their electoral pledges? Ideological stance in party publications vs spending and revenues of party governments: Do parties of the right and the left speak different languages? How can we validly classify a government as of the left or of the right? Is there a systematic difference between governments of the right and of the left in terms of their policy? Speeches by central bank officers vs monetary policy: Can changes in monetarypolicy be predicted by official speeches? The political business cycle: How can taking into consideration the speech-action relationship strengthen (or threaten) our knowledge about electoral and partisan cycles in public spending? Other questions explored include: Should policy makers always tell the truth and all the truth? What are the benefits and the costs of transparency? How can we resolve the apparent contradiction between the democratic demand for transparency and the efficiency requirement of secrecy in many policy areas (budget preparation, monetary policy, foreign policy, security, etc.)? Under which conditions is secrecy acceptable in a democratic society? To what extent may deception and lies lead to a breach of trust or to power abuse? What are the most efficient institutional mechanisms to prevent such abuse? Collectively, the authors present new insights for understanding political process and government activity, and suggest avenues for further research.
