Real earnings have increased for all demographic and skill groups within China’s urban labor market from the mid-1990s to the early 2000s. This paper analyzes these changes in earnings with respect to the relative supply and demand changes of each of the imperfectly substitutable labor inputs....

All of the demographic and skill groups in China's urban labor market received increases in their real earnings from the mid-1990s to the early 2000s. This paper analyzes these relative earnings increases with respect to the relative supply and demand changes for each of these imperfectly...

type="main" <p>The restructuring of the Chinese electricity sector in 2002 reshaped the market structure by vertically unbundling the dominant integrated firm and started the process of wholesale price liberalization. We estimate factor demands to study whether these reforms boosted productivity in...</p>

We study whether the 2002 deregulation and vertical unbundling of the Chinese electricity sector has boosted productivity in the generation segment of the industry. Controlling explicitly for sources of price-heterogeneity across firms and for firm-fixed effects, we find deregulation to be...

This paper investigates the relationship between environmental pollution and economic growth in China based on the environmental Kuznets curve hypothesis, using Chinese provincial data over 1985-2005. Waste gas, waste water and solid wastes are used as environmental indicators and GDP is used as...

Previous studies show that immigrants married to natives earn higher wages than immigrants married to other immigrants. Using data from the 1980-2000 U.S. censuses and the 2005-2010 American Community Surveys, we show that these wage premiums have increased over time. Our evidence suggests that...

Fault diagnosis for wind turbine transmission systems is an important task for reducing their maintenance cost. However, the non-stationary dynamic operating conditions of wind turbines pose a challenge to fault diagnosis for wind turbine transmission systems. In this paper, a novel fault...

Based on the Morlet wavelet transformation and Wigner-Ville distribution (WVD), we present a wind turbine fault diagnosis method in this paper. Wind turbine can be damaged by moisture absorption, fatigue, wind gusts or lightening strikes. Due to this reason, there is an increasing need to...
