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.     

The Impact of Corporate Governance Quality on Earnings Management: Evidence from European Companies Cross‐listed in the US

The study reported herein examines the impact of two central corporate governance mechanisms (internal audit function quality and board of directors’ quality) on the incidence of earnings management. Unlike most prior studies in the area, focused mainly on US firms, this study looks at European firms that are cross‐listed in the US and covers a long time span – before and after major changes were implemented in corporate governance policies (Sarbanes‐Oxley Act in the US and the 8th Company Law Directive in the European Union). Using novel and comprehensive measurement approaches for internal audit function quality and board of directors’ quality, we find that both mechanisms have a negative direct effect on the incidence of earnings management, while their interactive effect is positive. A longitudinal analysis of both mechanisms also reveals that internal audit function quality and the quality of boards of directors have increased significantly since the policy changes.     

Measuring rural consumers’ willingness to pay for quality labels using experimental auctions: the case of aflatoxin‐free maize in Kenya

Aflatoxins are a common health hazard in tropical countries, especially in rural areas. New methods to reduce aflatoxin levels in food staples, as well as cheaper test methods, are being developed, but consumers’ willingness to pay (WTP) for these improvements is unknown. A survey was conducted with a representative sample of rural consumers (1,344 in total, 63% women) in all major maize‐production zones of Kenya. The survey included an experimental auction with maize products of different qualities. The results showed that many rural consumers were aware of aflatoxins, but few understood their health risks. Respondents were willing to pay a premium for maize tested for aflatoxins and labeled, but asked a high discount for maize that was visibly contaminated with moldy grain. The premium was higher for respondents with education and in regions with aflatoxicosis outbreaks. Knowledge of aflatoxins substantially reduced the overall WTP, but did not increase the WTP for tested maize. Welfare analysis indicates that mandatory testing would result in substantial benefits if the cost of testing can be lowered to below the premium.     

The effect of natural and built environmental characteristics on pedestrian-vehicle crash severity in Ghana

Despite the benefits of walking as a means of travelling, walking can be quite hazardous. Pedestrian-vehicle crashes remain a major concern in Ghana as they account for the highest percentage of fatalities. The objective of this study is to determine the effect of both natural and built environmental features on pedestrian-vehicle crash severity in Ghana. The study is based on an extensive pedestrian-vehicle crash dataset extracted from the National Road Traffic Accident Database at the Building and Road Research Institute (BRRI) of the Council for Scientific and Industrial Research (CSIR), Ghana. Using a multinomial logit modelling framework, possible determinants of pedestrian-vehicle crash severity were identified. The study found that fatal crashes are likely to occur during unclear weather conditions, on weekends, at night time where there are no lights, on curved and inclined roads, on untarred roads, at mid-blocks and on wider roads. The developed model and its interpretations will make important contributions to road crash analysis and prevention in Ghana with the possibility of extension to other developing countries. These contributing factors could inform policy makers on road design and operational improvements.     

Female participation in African labor markets: The role of information and communication technologies

This article investigates the effects of information and communication technologies (ICT) on female labor force participation in a sample of 48 African countries. We specify and estimate linear regression and dynamic panel data models with fixed effects (FE) and system-generalized method of moments (SYS-GMM) estimation over the period 2001–2017. The three main results are that ICT use (mobile phone and internet) significantly stimulates female labor force participation in Africa; this effect is enhanced by financial development and female education; the effect of ICT on female employment in Africa is strongest in the industrial sector. These results remain robust to the provision of social, cultural, and institutional variables.
