Decisions about ""who gets what, when, and how"" are perhaps the most important that any government must make. So it should not be remarkable that around the world, public officials responsible for public budgeting are facing demands—from their own citizenry, other government officials, economic actors, and increasingly from international sources—to make their patterns of spending more transparent and their processes more participatory.Surprisingly, rigorous analysis of the causes and consequences of fiscal transparency is thin at best. Open Budgets seeks to fill this gap in existing knowledge by answering a few broad questions: How and why do improvements in fiscal transparency and participation come about? How are they sustained over time? When and how do increased fiscal transparency and participation lead to improved government responsiveness and accountability?Contributors: Steven Friedman (Rhodes University/University of Johannesburg); Jorge Antonio Alves (Queens College, CUNY) and Patrick Heller (Brown University); Jong-sung You (University of California—San Diego) and Wonhee Lee (Hankyung National University); John M.
