Book excerpt: "It opens to a spring day, when a middle-aged doctor named Dao-sheng leaves the mountaintop Taoist monastery where he has been living and sets out for the Region of the South, to the city he had once visited thirty years earlier and where his life had been irrevocably changed. He had then been a strapping but poor young musician traveling with a theater troupe. One evening, during a performance, he caught the eye of a well-born young woman named Lan-ying. Their contact lasted but a minute, but to them it felt like an eternity. For this act of audacity he was banished to hard labor by the girl's jealous fiance, the dissipated scion of a powerful family, who had witnessed their exchange and grasped its significance. Across the decades of a life spent either on the run or hiding out in monasteries, where he mastered medicine and divination, Dao-sheng never forgot Lan-ying. One exchange of glances had sealed something forever, something whose enduring power would decide their fates."--BOOK JACKET.

Download or read book Harvesting Prosperity written by Keith Fuglie and published by World Bank Publications. This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents frontier knowledge on the drivers of agriculture productivity to derive pragmatic policy advice for governments and development partners on reducing poverty and boosting shared prosperity. The analysis describes global trends and long-term sources of total factor productivity growth, along with broad trends in partial factor productivity for land and labor, revisiting the question of scale economies in farming. Technology is central to growth in agricultural productivity, yet across many parts of the developing world, readily available technology is never taken up. We investigate demand-side constraints of the technology equation to analyze factors that might influence producers, particularly poor producers, to adopt modern technology. Agriculture and food systems are rapidly transforming, characterized by shifting food preferences, the rise and growing sophistication of value chains, the increasing globalization of agriculture, and the expanding role of the public and private sectors in bringing about efficient and more rapid productivity growth. In light of this transformation, the analysis focuses on the supply side of the technology equation, exploring how the enabling environment and regulations related to trade and intellectual property rights stimulate Research and Development to raise productivity. The book also discusses emerging developments in modern value chains that contribute to rising productivity. This book is the fourth volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers.
