Analysis of Credit Risks in Asset-Backed Securitization Transactions in Singapore

Asset-backed securitization (ABS) is a relatively new financial instrument in Singapore's capital market, which has been accepted by developers (originators) as an alternative source of financing. Credit assessment and rating requirements have not been imposed on the ABS bond issues. Default-risk evaluation has also been understated, if not omitted, in the process of structuring ABS deals. This is the first study that applies a theoretical default-risky swaps valuation model to evaluate credit risks in ABS bonds in Singapore. The Monte-Carlo simulation results, based on the Century Square shopping mall ABS case, show significant effects of the changes in rental volatility and default-free interest rate volatility on the default-risk premium of swap. More specifically, an increase in the rental volatility reduces the default-risky swap values significantly. However, an increase in the instantaneous default-free interest rate volatility increases the default-risk premium of swaps, and this effect is only observed in the high default-free interest rate volatility regime (above 20 percent). The results suggest that the rental dynamics of the securitized real estate are critical in determining the default risks of ABS deals. The fixed-rate (coupon yield) and floating-rate (rental cash flows) should therefore be adequately determined to reflect the default risks, which may be caused by the rental dynamics of the securitized real estate.

对统一会计年度问题的思考

长期以来,我国实行统一的会计年度,所有单位的会计年度均自公历1月1日至12月31日止。在市场经济条件下,这种一刀切的会计年度不利于企业加强会计核算,政府加强监管,是造成会计信息失真、质量不高的重要原因之一,应尽快加以改革。现行统一会计年度存在的主要问题     

A Reexamination of Housing Price and Household Consumption in China: The Dual Role of Housing Consumption and Housing Investment

It is important to investigate the correlation between housing price and household consumption to gain an understanding of the behavior of the economy and effectively handle the consequences of economic development. In the last two decades, the accumulation of housing wealth by Chinese households has not been effectively transmitted to their final consumption. We discovered that the sustained increase in household wealth and housing-ownership rate in China has been accompanied by a decrease in consumption rate. We also identified a negative correlation between housing price and household consumption for both the homeowners who own one housing unit and those who own two units of housing. We investigated this phenomenon in China both theoretically and empirically by capturing the dual nature of housing as a consumption good and an investment vehicle. We found that the demand for second housing units is motivated by increasing housing consumption demand rather than pure investment needs. To explain the mechanisms that drive household-consumption behavior, we also explored the effects on household consumption of China’s educational system, marriage market and ageing society, as well as future housing-market uncertainty. The implications of government intervention in the housing market are discussed.     

House Price and co-Residence with Older Parents: Evidence from China

Numerous Chinese families choose to reside together with their elderly parents due to the considerable impacts of conventional values such as filial duty in Chinese society. However, as house prices rocketed up in major Chinese cities over the past decade, this arrangement is facing a sizeable challenge, therefore also raising new research question about it. This paper attempts to investigate the phenomenon of co-residence of adult children with their elderly parents in China. Using the 2013 data of China Household Finance Survey (CHFS), we document that house price is indeed a significant determinant for the pattern of intergenerational co-residence. Our empirical results can provide interesting insights into the important implication of rising house price for household residential arrangements in this country.     

微生物防腐剂在食品保鲜上应用

随着科技的发展,食品工业也得到快速发展,食品保鲜是食品界十分关注的问题。在食品保鲜中常用的微生物防腐剂是一类由微生物产生的食品防腐剂,它能抑制微生物的生长或直接杀死微生物,是一种天然、安全、高效的防腐剂,在食品保鲜界的应用越来越广泛。本文首先分析微生物防腐剂的种类,然后具体介绍了在食品保鲜中使用最广泛的乳酸链球菌素和纳他霉素的具体应用,对于微生物防腐剂在食品保鲜上的应用有很强的现实意义。     

关于计量生产管理系统的研究

随着现代公司企业生产经营逐渐趋于标准化、自动化,传统的办公系统已经无法满足日常生产经营的管理需要,本文通过对计量院管理流程的工作模式进行分析,提出了先进的计量管理系统设计方案,设计并实现了可视化流程定制控件和表单定制模块,可视化流程定制很大程度减少了因业务流调整而导致的重复开发工作,大大提高了工作效率.     

中国对印度的商品出口现状分析

随着中印经济的高速增长和全球化进程的不断深入,两国在国际市场上的地位迅速提高。在此背景下,两大邻国之间的贸易从理论上来看也应该得到相应的发展和深化。然而,本文通过对1992年以来中国对印度出口数据的分析发现,尽管过去20年中国对印度的出口绝对量增长很快,但是从相对量来看,中印双边贸易强度一直低于其它主要贸易伙伴,近年来甚至有中国对印度出口不断乏力的趋势。文章进一步分析了中国对印度的出口结构和贸易成本并发现,导致对印度出口乏力的主要原因有:出口契合度低、产业内贸易低、贸易成本下降的空间有限等。     

阻断性压力源与工作-家庭冲突:谦卑和学习目标导向的调节作用

基于资源保存理论和压力交互模型,本研究探讨了阻断性压力源对工作-家庭冲突的影响及其边界条件.对国内120名企业员工的数据分析结果表明,阻断性压力源正向影响工作-家庭冲突,除此之外,谦卑和学习目标导向共同调节了阻断性压力源和工作-家庭冲突之间的关系,具体地,当谦卑和学习目标导向均高的时候,阻断性压力源与工作-家庭冲突之间的正向关系最弱;相反,对于谦卑和学习目标导向均低的个体来说,阻断性压力源对工作-家庭冲突的正向影响最强.
