工资性收入不平等：基于户籍歧视的分析

文章利用2012年中国城镇居民与流动人口收入调查数据,采用不同的工资分解方法,从地区分割、职业分割和收入阶层的角度测算并分析了户籍工资差异及户籍歧视情况。实证结果表明,户籍歧视在不同经济发展区域都存在;户籍歧视的加剧体现在工资歧视和就业歧视两方面;对于极低工资、低工资和较高工资的劳动者而言,户籍歧视带来的收入不平等问题相当严重。     

Are Minorities or Minority Neighborhoods More Likely to Get Low Appraisals?

We empirically examine the role of appraisal in the residential mortgage lending process—in particular, the incidence, consequences, and determinants of appraisal below contract purchase price. Using the Boston Federal Reserve Study data set, we find that, as expected, low appraised value significantly increases the probability of mortgage loan application rejection. We find no evidence that low appraised value is related to census tract racial composition, an important finding given the history of the appraisal industry; however, low appraised value is related to proxies for neighborhood quality. Moreover, properties securing adjustable rate mortgages, condominiums, and properties purchased by African American buyers show an increased probability of low appraisal, though the race effect result is highly sensitive to model specification.     

关于领导赏识的正面辨识度研究

“辨识度”一词由音乐中音色的辨识度引申而来,是指辨别、认识的程度。用来形容人,就是指一个人的个性、特点的与众不同。辨识度高就是因为拥有某些特殊的特质,从而得以脱颖而出。干部的正面辨识度,就是指一名干部给人留下的正向的、积极的印象。每个人都有不同的特点,不同的领导欣赏的下属也有不同的特质。为此,论文对下属易被领导赏识的正面辨识度展开探究。     

A State‐Price Volatility Index for China's Stock Market

This study derives a volatility index for China's stock market with similar properties to the Chicago Board Options Exchange Volatility Index (the ‘VIX’). A long‐term benchmark of historic volatility expectations is here presented for China from 1996 to 2011, called the ‘China‐ State‐Price Volatility (SPV)’. Construction of this index involves the use of SPV methodology, using implied volatility calculated from options on the Hang Seng China Enterprise Index (HSCEI). Historic open–high–low–close volatility on the Shanghai Composite Index (SHCI) is also used to extend the benchmark prior to the availability of HSCEI options data. The China‐SPV successfully forecasts realised volatility for the Shanghai Stock Exchange. It also serves as a ‘fear gauge’ in that it monitors daily movements of the SHCI in the same way that the VIX monitors the S&P 500 index (Whaley, 2009). The China‐SPV evidences an increasing relation with the US market in terms of the dynamic correlation of levels and changes with the VIX since 2004.     

Logarithmic quasi-homothetic preferences

We study a class of quasi-homothetic preferences, which result in demands that are logarithmic in own prices when these have a negligible impact on aggregate prices (as in monopolistic competition models). Thus marginal revenues are computationally friendly and well behaved.
