|June 2012||Water Availability as a Constraint on China's Future Growth|
with John Whalley: w18124
Recent writings on China's water situation often portray China's water problems as severe and suggest that water availability could threaten the sustainability of China's future growth. However, China's high growth of the last 20 years or more has been obtained with relatively little increase in the physical volume of water. In this paper, we use a growth accounting approach to investigate both the contribution played in the past by water availability in constraining China's growth performance, and what would be involved in the future. We use a modified version of Solow growth accounting in which water in efficiency units enters the production technology, and investment in water management assets raises efficiency of water use. Our results suggest that if investments in water assets in the...
|December 2011||The Contribution of China, India and Brazil to Narrowing North-South Differences in GDP/capita, World Trade Shares, and Market Capitalization|
with Jing Wang, John Whalley: w17681
This paper focuses on the contribution to recent narrowing of the gap between Northern and Southern economies in GDP/capita, shares in world trade and market capitalization attributable both jointly and single to China, India, and Brazil (the three currently largest rapidly growing Southern economies). We report North‐South differences in GDP/capita which (depending slightly on definition of North and South, as well as price deflators used) fall from 22 to 15.9 in constant USD between 1990 and 2009, changing Northern and Southern shares in world trade which fall for the North from 82.3% to 64.4% and rise for the South from 17.7% to 35.6%, and a changing North‐South gap in stock market capitalizations from 27.6 to 3.3 over the same time. In contrast the North‐China gap falls from 57.2 to 13...
