With China’s rapid economic development and urbanization process, cities are facing great challenges for tackling anthropogenic climate change. In this paper we present features, trajectories and driving forces for energy-related greenhouse gas (GHG) emissions from four Chinese mega-cities...

The North China Plain (NCP) covers an area of around 328,000 km2 and is one of the most important regions of cereal crop production in China. Wheat and maize rotations and one season cotton are the most common cropping systems. The region contributes at an amount of about 50% to the countries...

The detection of the community structure in networks is beneficial to understand the network structure and to analyze the network properties. Based on node similarity, a fast and efficient method for detecting community structure is proposed, which discovers the community structure by...

We estimate a structural model of optimal life-cycle housing and nonhousing con- sumption in the presence of labor income and house price uncertainties. The model postulates constant elasticity of substitution between housing service and nonhousing consumption, and explicitly incorporates a...

In this article, we explore whether relative risk aversion varies with wealth. First, we derive theoretical predictions on how risky shares respond to wealth uctuations in a portfolio choice model with both external habits and time-varying labor income. Our analytical results indicate that: (1)...

Do immigrants have better labor-market outcomes under Democratic governors? By exploiting variations associated with close elections in a regression discontinuity (RD) design applied on gubernatorial elections in 50 states over the last two decades, we find that immigrants are more likely to be...
