|October 2015||Measuring Changes in the Bilateral Technology Gaps between China, India and the U.S. 1979 - 2008|
with Jing Wang, John Whalley: w21657
Popular literature suggests a rapid narrowing of the technology gap between China and the U.S. based on large percentage increases in Chinese patent applications, and equally large increases in college registrants and completed PhDs (especially in sciences) in China in recent years. Little literature attempts to measure the technology gap directly using estimates of country aggregate technologies. This gap is usually thought to be smaller than differences in GDP per capita since the later reflect both differing factor endowments and technology parameters. This paper assesses changes in China’s technology gaps both with the U.S. and India between 1979 and 2008, comparing the technology level of these economies using a CES production framework in which the technology gap is reflected in the ...

|June 2013||Capital-Labor-Energy Substitution in Nested CES Production Functions for China|
with John Whalley: w19104
In the CGE based policy modeling literature, especially recent literature on policy modeling for global climate change, nested CES production functions over multiple inputs have been widely used. Although lack of reliable estimates of substitution elasticities for nested structures has been acknowledged for a long time, the problem has not yet been solved satisfactorily. This is especially the situation for the Chinese case for which modeling work has global implications. This paper reports estimates of substitution elasticities for normalized nested CES aggregate production functions for China with different nested structures of input factors: capital, labor with or without human capital adjustment, and energy using data for the period 1979-2006. We adopt grid search based non-linear opti...
