Heterogeneity and long-run changes in aggregate hours and the labor wedge

From 1961 to 2007, U.S. aggregate hours worked increased and the labor wedge—measured as the discrepancy between a representative household׳s marginal rate of substitution and the marginal product of labor—declined substantially. The labor wedge is negatively related to hours and is often attributed to labor income taxes. However, U.S. labor income taxes increased since 1961. We examine a model with gender and marital status heterogeneity which accounts for the trends in the U.S. hours and the labor wedge. Apart from taxes, the model׳s labor wedge reflects non-distortionary cross-sectional differences in households׳ hours worked and productivity. We provide evidence that household heterogeneity is important for long-run changes in labor wedges and hours in other OECD economies.     

转型期中国经济增长方式转变的金融支持——基于经济学文献的探讨

本文基于经济学文献探讨了转型期中国经济增长方式转变的金融支持问题。研究发现,不论从整体还是从区域层面来看,中国的金融发展主要是通过加速资本积累来促进经济增长的;而对资本配置效率的改善、技术进步及TFP增长率的提高,作用并不明显。因此,这种金融发展模式不利于中国经济增长方式从"粗放型"向"集约型"的转变。本文进一步指出,财政分权背景下的地方政府行为及其对区域金融发展的影响,是造成金融资金配置效率低下和经济增长方式转变困难的重要原因。     

Rogoff revisited: The conservative central banker proposition under active fiscal policies

The paper re-examines Rogoff's [Rogoff, K., 1985. The Optimal Degree of Commitment to an Intermediate Monetary Target. Quarterly Journal of Economics 100, 1169–1189.] influential monetary policy result. It shows that responses of a conservative central banker and the resulting macroeconomic outcomes may be substantially different if interactions with (ambitious) fiscal policy are taken into account.

Intention to stay in Chinese foreign-invested companies: previous experiences,initial expectations and current satisfactions

The problem of retention of professional employees has become a prime challenge for foreign-invested companies in China. The present paper aims to examine the predictors of intention to stay of local Chinese white-collar employees in foreign-invested companies with a multi-dimensional approach. Through the examination and comparison of models incorporating previous experiences, initial expectations and current satisfactions, the results of this study indicate that while current intrinsic and contextual satisfaction might contribute to improving the intended stay period, current extrinsic satisfaction might not be as critical as expected. Furthermore, for individuals with voluntary turnover experiences, cumulative extrinsic and contextual satisfaction gaps (gaps between satisfaction with previous and present workplaces) might explain a higher degree of intention to stay. Aligned with the result that the number of overall voluntary turnover times is negatively related with the intended stay period, this study implies that future studies should further explore the possible influences of previous experiences on how an individual would like to maintain their employment relationship with their present company.
