Ownership, institutions, and capital structure: Evidence from China

We employ a unique data set to explore the role of ownership structure and institutional development in debt financing of non-publicly traded Chinese firms. We show that state ownership is positively associated with leverage and firms’ access to long-term debt, while foreign ownership is negatively associated with all measures of leverage. Surprisingly, firms in better developed regions are associated with reduced access to long-term debt, suggesting the availability of alternative financing channels and the tightening of the lending standards under the on-going banking reform. The combination of ownership structures and institutions explains up to 6% of the total variation in firms’ leverage decisions, while firm characteristics alone explain no more than 8% of the variation. Further, we show that non-state-owned firms tend to have lower total and short-term debt than their state-owned counterparts in less developed regions. Finally, we show that state-owned firms’ easy access to long-term debt is positively associated with long-term investment and negatively associated with firm performance.     

信用卡透支纠纷的法律适用

近年来信用卡透支纠纷急剧上升。信用卡透支纠纷法律关系相对简单,但是在审判实践中还有很多问题难以处理。本文分别从原告主体资格、管辖法院、违约的界定、利息、复息与合法性违约金的调整、诉讼费用与持卡人应诉差旅等费用的承担、举证责任分配与转移、诉讼时效中断的认定、信用卡透支案件中的刑民交叉问题等几个方面进行针对性的分析与讨论。

Bayesian U-type design for nonparametric response surface prediction

This paper deals with Bayesian design over U-type designs of n runs and s factors with q levels for nonparametric response surface prediction. The criterion is developed in terms of the asymptotic approach of Mitchell et al. (Ann Statist 22: 634–651, 1994) for a specific covariance kernel. An optimal design is given in approximate design theory over the all level combinations. A connection with orthogonality and aberration is established. A lower bound for the criterion is provided, and numerical results show that this lower bound is tight.     

Bayesian robust designs for linear models with possible bias and correlated errors

Consider the design problem for the approximately linear model with serially correlated errors. The correlated structure is the qth degree moving average process, MA(q), especially for q = 1, 2. The optimal design is derived by using Bayesian approach. The Bayesian designs derived with various priors are compared with the classical designs with respect to some specific correlated structures. The results show that any prior knowledge about the sign of the MA(q) process parameters leads to designs that are considerately more efficient than the classical ones based on homoscedastic assumptions.
