A Neural Network Analysis of Mortgage Choice

There exists today an unanswered question as to whether, and the degree to which, borrower characteristics impact the choice between fixed and adjustable rate mortgages. In this paper, we apply a neural network analysis to supply evidence that answers this question. We find evidence that the characteristics of a borrower's net worth, marital status and education level and whether a co-borrower is involved contribute in a significant way to the neural network's ability to determine mortgage choice. Further, we show how, because of the facility of neural networks in modeling intrasample differences, they achieve material and statistically significant accuracy gains over qualitative choice models in predicting whether a borrower will choose a fixed or adjustable rate mortgage.     

Shareholder litigation and toxic releases

We examine the environmental impact of the staggered adoption of universal demand laws by 23 U.S. states between 1989 and 2005. Universal demand laws impede derivative lawsuits and thus undermine shareholder oversight of corporate environmental performance. We find that weakened litigation rights for shareholders are positively associated with the release of toxic chemicals by firms. The effect is stronger for firms with weak governance, and environmental mismanagement by firms after the passage of the laws lead to poorer financial performance. Overall, our findings imply that derivative lawsuits by shareholders are not frivolous, as is often asserted. Rather, they act as an effective mechanism of corporate governance.

Greening Asia's Economic Development

Asia is facing serious environmental challenges including urban air pollution and the effects of global climate change. As a major source of greenhouse gases, what happens in Asia will play a crucial role in determining the extent to which the world warms over coming decades. This paper reviews key environmental challenges faced by the region and the growing opportunities for a transition to a cleaner economy powered by zero‐emission energy sources. Economic mechanisms – including emissions pricing, reverse auctions, and renewable portfolio standards with green certificate schemes – have the potential to underpin a much greener development model for the Asian Century.

Injury prevention priority setting based on the National Injury Surveillance data in Korea

For the reduction of injury burden, injury prevention efforts are essential. However, financial, material and human resources are far from sufficient, and this situation necessitates setting priorities for effective injury prevention. Hence, the aim of this study is to prioritise 13 injury mechanisms for prevention of injury using four injury burden criteria. National death certificate, hospital discharge data and emergency data during 2004 were used. According to the 13 most frequent injury mechanisms (ICD-10), mortality priority score, years of potential life lost (YPLL) priority score, morbidity priority score and hospital charge priority score were calculated. Injury mechanisms which were ranked fourth or higher on at least three of the four criteria scores were arranged in rank orders. Traffic crashes ranked highest on all four of the priority criteria for injury prevention followed by fall and poisoning in second and third positions, respectively. Categorised by age groups, in 0-19 year olds, traffic crashes, suffocation and drowning; in 20-59 years, traffic crashes, suffocation and poisoning; and in 60 and over, traffic crashes and fall were shown to be significant injury prevention priority in rank orders. Injury prevention priorities identified from this study could be useful in strategically allocating limited resources and implementing more focused prevention policies in Korea.
