Identifying the Transition from Efficient-Market to Herding Behavior: Using a Method from Econophysics

We test whether “detrended fluctuation analysis” (DFA)—an econophysics method—identifies the transition from efficient-market trading to herding behavior and the rise of the NASDAQ dot.com stock market bubble. DFA divides a time series into “segments” of varying lengths and then tests whether power-law distributions exist within the segments. A power-law distribution of stock-price changes within a segment indicates herding behavior and the start of the dot.com bubble. The clarity of the transition indication depends on both segment lengths and segment starting dates. Our findings show that DFA can be used to identify the beginning of stock-market bubbles but not the beginning of crashes.

Production in incomplete markets: Expectations matter for political stability

In the present paper we study voting-based corporate control in a general equilibrium model with incomplete financial markets. Since voting takes place in a multi-dimensional setting, super-majority rules are needed to ensure existence of equilibrium. In a linear–quadratic setup we show that the endogenization of voting weights (given by portfolio holdings) can give rise to – through self-fulfilling expectations – dramatical political instability, i.e. Condorcet cycles of length two even for very high majority rules.

金融危机背景下农民工就业能力研究

由美国次贷危机而引发的全球金融危机对日益融人世界经济体系的我国也造成了日渐严重的冲击,从2008年10月以来,已经有数百万的农民外出务工者由于工厂倒闭或歇工而被迫提前返乡。有关数据显示,中小企业吸收了我国就业农民工当中的75％,当一批中小企业在金融风暴中破产倒闭或者停厂歇业时,农民工就会收到最直接的冲击,农民工的就业出路就成了大问题。在金融危机造成严峻的就业形势下,如何提升外出务工农民的就业能力就成了至关重要的问题。     

Cultural determinants of human capital accumulation: Evidence from the European Social Survey

Although economists commonly view the accumulation of human capital as a key driver of economic development, what drives cross-country differences in human capital accumulation remains poorly understood. I use an epidemiological approach involving second-generation migrants to test for a possible cultural gradient in individuals’ propensity towards human capital accumulation. Results indicate a strong relationship between country-of-origin culture and human capital accumulation and are robust to using years of education instead of individuals’ engagement in human capital accumulation as the dependent variable. Drawing on dimensions of cultural differences identified in culture frameworks developed by cross-cultural researchers, results further suggest that cultural emphasis on intellectual autonomy helps explain part of the observed differences in human capital accumulation. However, further work is needed to complete our understanding of the cultural roots of individuals’ propensity towards human capital accumulation.     

OFDI逆向技术溢出、制度质量与区域创新能力

基于2005—2016年我国省际面板数据,首先通过OLS、DIFF GMM、SYS GMM3种基准线性回归方法论证了OFDI逆向技术溢出对我国区域创新能力的促进作用。以OFDI为核心解释变量,分别构建以地区腐败、市场化程度和知识产权保护为门槛变量的动态门槛回归模型。结果发现：随着地区腐败程度加深,我国区域创新能力逐渐减弱;以市场化程度、知识产权保护为门槛变量,跨越门槛点后OFDI对我国区域创新能力的拉动作用依次增强。最后,结合面板向量自回归模型进一步研究对外直接投资过程中地区腐败、市场化程度和知识产权保护对区域创新能力的动态即期冲击。结果显示:市场化程度单位变动对区域创新能力的影响呈现正向冲击且持续性较强,知识产权保护对区域创新能力的拉动最为迅速但后期持续性较弱,地区腐败对区域创新能力产生负向冲击作用。
