Do Nutrition and Health Affect Migrant Workers＇ Incomes？ Some Evidence from Beijing,China

Migrant workers have become a major element of the labor force in Chinese cities, making important contributions to the economy while forming a socially disadvantaged group. Existing research on the relationship between the level of nutrition and health and income in China mainly focuses on farmers living in rural areas. Based on a Mincer equation and using a survey in Beijing, this paper examines the relationship between migrant workers＂ nutrition and health levels and their monthly incomes. We find that the nutrition intake and the body mass index have positive effects on income while duration of illness and daily working hours have negative effects. These conclusions imply that the Chinese Government should put more emphasis on improving migrant workers＇ well-being, including offering educational programs on nutrition and health, and enhancing medical insurance and the old-age insurance system.

论使用净价进行业绩考核之不合理性

净价虽然能够反映出债券市场收益率的变动和行情的变化,但是却不是一个精确的指标,在实践运用中往往会出现误差。特别是在收益率变动幅度较小的情况下,还会产生严重的方向性错误。因此,建立一个合理有效的债券投资考核体系,除了要继续研究如何推出更有指标意义的债券指数之外,深化金融机构的体制改革,建立内部全面的考核体系,也是必不可少的一环。     

Is There a ＂Middle-income Trap＂？ Theories, Experiences and Relevance to China

Through review of relevant studies and analysis,this article indicates that the "middle-income trap " is in line with the framework of the mainstream economic growth theories, and,therefore,it is a useful concept through which we can analyze economic growth phenomena in specific economic growth phases.The empirical experiences of many countries also indicate that at specific middle-income stages,economies with high rates of growth tend to encounter economic slowdown or even stagnation.The article shows that China is facing the challenge of determining how to move smoothly beyond the middle-income stage of economic development,while taking into account the shifting population structure,changing resource endowment and growth patterns.The article,drawing on international experiences, puts forward several policy suggestions relating to improvement in total factor productivity, expansion of human capital accumulation and deepening of system and government function reforms.     

China＇s ApprOach to Rebalancing： A Conceptual and Policy Framework

This article seeks to develop a conceptual and policy framework for understanding China’s role in the global economic imbalances.China’s contribution to these imbalances via recurrent trade and financial surpluses corresponds with a phase of deepening structural risks to China s economic growth and development.These structural challenges include:the composition of growth resulting from China’s dynamic internal transformation,China’s trade orientation,the trajectory of resource use and Commissions,welfare problems relating to distribution and international constraints.This article develops a conceptual framework for examining the relationship between the processes of long-run structural transformation in China,its economic imbalances,and the role of institutional reform in dealing with these structural challenges.As such,economic policy should extend beyond short-term macro management to pursue an institutional reform agenda to facilitate broader structural change to mitigate constraints to future growth and to improve economic welfare.
