配股融资股价效应的实证研究

随着我国股市的发展，上市公司的融资方式也不断创新，配股融资作为股权融资的一种方式逐渐成为上市公司再融资的首选。配股融资虽然具有许多优点，但是我国上市公司没有充分发挥配股融资的长处，为了“圈钱”而“圈钱”，并且资金配置效率低下，对股市的负面影响日渐突出。通过2000年实施配股的43家样本公司配股公告日股价的变动，对配股融资的股价效应进行实证分析，并提出相应的政策建议。     

新股发行主体行为和博弈分析

新股发行市场较小的市场厚度使得理论分析不仅要涉及一般的供给需求分析,还必须深入研究供给和需求的形成过程以及供求双方的相互作用。本文拟从博弈角度研究新股发行过程政府、发行公司、中介机构和投资者的行为特征和多主体博弈过程,分别从信息完全和信息不完全两个角度研究博弈过程和结果,以期对新股发行制度改革提供初步的理论分析基础。     

Forecasting recovery rates on non-performing loans with machine learning

We compare the performance of a wide set of regression techniques and machine-learning algorithms for predicting recovery rates on non-performing loans, using a private database from a European debt collection agency. We find that rule-based algorithms such as Cubist, boosted trees, and random forests perform significantly better than other approaches. In addition to loan contract specificities, predictors that refer to the bank recovery process — prior to the portfolio’s sale to a debt collector — are also shown to enhance forecasting performance. These variables, derived from the time series of contacts to defaulted clients and client reimbursements to the bank, help all algorithms better identify debtors with different repayment ability and/or commitment, and in general those with different recovery potential.     

从京东方负债扩张看我国的杠杆收购

20上世纪80年代风靡美国的杠杆收购方式以其巨大的溢价空间和较高的财务、经营风险引起理论学者的研究和实践人士的青睐。我国现阶段,实行杠杆收购有着非常深远的影响和广阔的空间,但仍存在许多制约因素,如法律不完善、资本市场弱式化、投资银行不发达、管理人员素质不高等。

公司债务期限结构影响因素的实证分析

本文以上市公司板面数据及横截面数据为基础,利用混合时间序列回归、横截面回归和固定效果回归等方法,对影响我国上市公司债务期限结构的因素进行了实证检验。结果发现,除契约成本假说中成长机会外,绝大部分因素的检验结果与预期一致,进而验证了其适用性;经验证据不支持信息不对称假说;对税负假说相关因素的检验结果表现出不确定性;期限匹配假说得到了支持。研究还证明,具有较少自由现金流量、杠杆水平较高、规模大、受到管制和资产期限长的公司具有更多的长期债务。     

How to reform China’s fiscal system?

ABSTRACT

As the population aging, China’s government expenditures, including general fiscal expenditure, healthcare and social security expenditure, will grow more rapidly than government revenues, tending to elevate government debt. Local governments undertake overwhelming 85% of total general fiscal revenue and are responsible for healthcare and social security, and their debt has been growing. Fiscal reforms are imperative, including tax reforms, the structure of government spending reforms, social security reforms, healthcare reforms, local public finance reforms, and central and local government’s fiscal relationship reforms. This paper will explore the fiscal challenges China faces and discuss how to reform the fiscal system to cope with these challenges.     

中国地方政府债务权责划分:实践探索与改革建议

地方政府债务权责划分是一国分级财政体制的重要内容。实现中国地方政府债务的合法化已经成为解决当前地方政府债务问题的前提条件。地方政府债务的合法化不仅是债务融资权的界定问题,更是管理责任的归属问题。近年来中国某些地方已经开始自发地探索地方层面上的政府债务权责划分的方法。国家应尽快制定统一的法规,赋予地方政府合法举债权,但应严格控制债务规模、界定使用范围。应在财政部和省市县财政部门设立债务管理机构,明确地方政府的债务偿还及风险管理责任,加大债务监督力度。     

The effectiveness of interest-rate futures contracts for hedging Japanese bonds of different credit quality and duration

This study investigates the effectiveness of the Tokyo Stock Exchange (TSE)-traded Japanese 10-year JGB futures contract to hedge portfolios of Japanese bonds of differing maturity and credit quality. The bond portfolios examined are Government, AAA-, and AA-rated Eurobonds with maturities of 2, 3, 5, 7, 10, and 20 years. Consistent with the recent literature, the study employs univariate methods for calculating hedge ratios based on levels, first differences, and percentage change of each series. Out-of-sample forecasting is used to determine the effectiveness of the calculated hedge ratios for each of the bond portfolios and to determine which approach to calculating hedge ratios is the most effective. The results show that this particular futures contract does provide a good hedge, particularly for those bond terms closest to the 10-year term of the contract. There is some evidence, although not strong, that JGBs are better hedged than AAA and AA bonds. Investors should take some caution when using this futures contract to hedge bond portfolios of different maturities and credit ratings.     

Household indebtedness in Korea: Its causes and sustainability

This paper investigates why household debt in Korea has increased so rapidly over the past decade and whether it is sustainable, adopting a multi-faceted approach which includes a time series analysis, a quantitative analysis based on household panel data, and an analysis using a debt dynamics equation derived from the household budget constraint. A regression analysis reveals that household debt growth has been significantly related to house price increases, banks’ lax attitudes toward household lending, and financial institutions’ favorable funding conditions. Also 70–80% of the total debt increase has been accounted for by high income or newly indebted households. The debt dynamics equation analysis shows that the rapid rise in the ratio of household debt to disposable income is attributable not only to the increase in household asset purchases but also to the dampened growth in disposable income and the reduced savings rate. The sustainability analyses indicate that Korean households’ debt sustainability is unlikely to deteriorate sharply within a short period of time unless two extreme scenarios, under which house prices decline by 5% a year over the next five years, or a significantly large macroeconomic shock similar to the 1997 crisis hits the economy, would be realized.
