Development', would call some 15 years later for a data revolution for sustainable development post-2015 as follows:We also call for a data revolution for sustainable development, with a new international initiative to improve the quality of statistics and information available to citizens. We should actively take advantage of new technology, crowd sourcing, and improved connectivity to empower people with information on the progress towards the targets. (Chapter 4, Implementation, Accountability and Building Consensus, p. 21.) xvi As Director of the United Nations University World Institute for Development Economics Research (UNU-WIDER) since 2009 and in this capacity in recent years as a member of the UN Task Team for the formulation of the post-2015 development agenda, I have come to appreciate these demands for international action. The HLP call for a data revolution is most pertinent, and I note that while substantial improvements in statistical systems have been registered in many developing countries over the past two decades, performance remains poor in far too many sectors and countries. The HLP notes, for example, that more than 40 countries lack sufficiently strong systems to properly track trends in poverty; and the panel also notes unsatisfactorily high time lags for reporting MDG (Millennium Development Goals) outcomes.Recently, large-scale revisions of GDP estimates in Ghana and Nigeria as well as elsewhere serve as reminders of broad-based weaknesses in statistical systems that persist across the developing world, including not only Africa but also the Asia-Pacific region. On this background-and recalling UNU-WIDER's long-standing expertise in innovation in data collection and analysis-leads me to strongly confirm the view that data will be at the centre of the development action post-2015.At the same time, while the logic of a concerted push towards a 'data revolution' is compelling, these calls are often rather fluffy-and it is indeed not entirely clear from ongoing debates that it is widely understood what such a revolution actually requires and means in concrete practice.The aims of this volume were formulated with these concerns in mind using Viet Nam as a case due to the concrete and unique, but coincidental, availability of the solid VARHS experience and panel data set. Furthermore, Viet Nam's contemporary similarities to a large number of developing economies make its experience and policy recommendations, based on analysis of microeconomic data, highly relevant for many regional and extraregional stakeholders. In fact, Viet Nam provides an exceptionally informative environment in which to observe and consider the economic and social mechanisms underlying: A rural economy in transformation, The critical importance of key production factors and institutions, and The complex set of welfare outcomes and distributional issues.These dimensions are therefore the three component parts of this volume, identifying throughout the associated policy challenges after setting the scene in the...
