KIBS企业—顾客交互创新中知识整合的权变机制

引入过程互依性和项目不确定性,探讨了KIBS企业-顾客交互创新中知识整合的权变机制。基于338份服务创新项目问卷数据进行实证研究,结果显示:在KIBS企业-顾客交互四要素中,除规则正式化负向影响外部知识整合以外,决策集体化、资源共享和任务协作均正向影响内、外部知识整合;过程互依性增强了规则正式化、决策集体化和任务协作对内部知识整合的影响,但对资源共享与内部知识整合间关系的调节作用不显著;项目不确定性增强了规则正式化、资源共享和任务协作对外部知识整合的影响,但对决策集体化与外部知识整合间关系的调节作用不显著。

CRIME AND POVERTY: A SEARCH‐THEORETIC APPROACH*

Numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities. We study this phenomenon in the context of a search‐equilibrium model, in which agents choose between formal employment and pursuing crime‐related activities (theft). Prior to their “occupational choices,” agents undertake costly schooling, raising their productivity. Crime acts, in essence, as a tax on human capital by affecting the probability that a worker's earnings (possessions) are subsequently appropriated. There are multiple equilibria. High crime, low levels of educational attainment, long spells of unemployment, and poverty are correlated across them.     

基于顾客忠诚理论的团购营销策略研究

河南省农业信息化水平评价

综合国内外学者的农业信息化评价研究成果,结合河南省农业信息化发展的实际情况,遵循数据可得性等原则,构建了包括5个一级指标、14个二级指标的河南省农业信息化水平评价指标体系,建立了河南农业信息化水平测度模型,计算了2005—2010年河南省农业信息化水平总指数。最后指出推动和制约河南省农业信息化水平提高的因素。     

城市化与城市资源消耗间关系的实证研究——以北京市为例

建立基于误差修正模型的Granger因果关系模型,检验分析了北京的城市化与城市资源消耗之间的因果关系。结果显示:在短期内,北京的城市化与城市资源消耗互为Granger因果关系;在长期内,仅存在从城市化到城市资源消耗的单向Granger因果关系,这表明当前及今后很长一段时间内北京城市化仍较多依赖资源消耗。最后指出建立有助于节约资源的城市化推进模式是实现北京市可持续发展的根本路径选择。

On the determinants of household debt maturity choice

This article jointly analyses a behavioural and a cultural concept to explain household debt portfolio choice. The behavioural approach explores the role of time preferences on household debt maturity in a theoretical model and a numerical analysis. We derive a positive relationship between the long-term discount factor δ and the optimal maturity of household loans. The cultural approach examines whether national culture is a reasonable predictor for household debt maturity. We show that culture is an important factor for households’ borrowing decisions and has even more predictive power than time preferences. Countries with higher scores on the Hofstede dimension of long-term orientation tend to have shorter household debt maturity. Time preferences incur a primarily mediating role, because the effect of national culture on the borrowing decision is reduced, as the long-term discount factor δ increases.     

Expected risk and excess returns predictability in emerging bond markets

This study examines the predictability of expected excess returns from eight emerging bond markets within an international asset pricing framework. Two sets of instruments are used, which include both world and local factors, to forecast emerging bond returns. Besides investigating the influence of the macroeconomic factors in specific countries on bond returns in those countries, this study also divides local factors into macroeconomic and financial factors. Unlike previous studies, we apply macroeconomic instruments that contain more information on excess returns as a proxy for local risk factors via principal component analysis methodology. The information variable approach enables the prediction of excess bond returns based on world and local factors and facilitating understanding of the degree of integration between emerging bond markets and developed bond markets. The results indicate that the bond market in emerging world is partially integrated to that in the developed world and the predictability of local factors that include both financial and macroeconomic information variables can forecast around 25–66% of the returns of emerging bonds. Incorporating the macroeconomic variables increases the explanatory power of the model. Both world and country-specific local instruments can forecast excess bond returns, but local instruments appear to be better predictors of such returns, particularly the local credit spread to US. Additionally, this study finds that investor risk aversion is significant among most of sample countries.
