WHY DO CHILDREN TAKE CARE OF THEIR ELDERLY PARENTS? ARE THE JAPANESE ANY DIFFERENT?

We conduct a theoretical and empirical analysis of why children live with (or near) their parents and provide care and assistance to them using microdata from a Japanese household survey, the Osaka University Preference Parameter Study. We find that the Japanese are more likely to live with (or near) their elderly parents and/or to provide care and attention to them if they expect to receive a bequest from them, which constitutes strong support for the strategic bequest motive, but that their caregiving behavior is also heavily influenced by the strength of their altruism toward their parents and social norms.     

国外铁路复兴浅析

19世纪铁路发展初期,受益于股份公司的财产组织形式和政府的扶持,铁路得到迅猛发展。随着铁路建设的迅猛发展,英、德、加、美、法等国铁路网相继形成,铁路成为最主要的运输方式,这些国家政府为调节铁路运输公司与货主、公众的利益,开始对铁路实行经济管制,特别是对运价实施控制。另一方面,在运输市场的激烈竞争中,各种运输方式受控程度差别悬殊,不必要的枷锁束缚是使铁路在竞争中处于不利地位的决定性因素。在第二次世界大战前后,资本主义发达国家为了摆脱危机,弥补市场功能缺陷,严格控制某些非竞争性企业和战略企业,掀起了企…     

A Survey Study of Japanese Managers' Views of Business Ethics

In the United States, a series of survey studies have been done to examine corporate managers' views of business ethics and various business practices (Baumhart, 1961; Brenner and Molander, 1977; Vitell and Festervand, 1987). This paper is a replication study conducted in Japan of those American studies. The results of the study suggest that Japanese managers tend to be more situational in their ethical orientation than Americans. The results also show that the company policy on ethics is the most important factor influencing Japanese managers' ethical decisions.     

Do the Retired Elderly in Europe Decumulate Their Wealth? The Importance of Bequest Motives,Precautionary Saving,Public Pensions,and Homeownership

We use microdata on a large number of European countries from the Survey of Health, Ageing and Retirement in Europe (SHARE) to examine the wealth accumulation (saving) behavior of the retired elderly in Europe. We find that less than half of the retired elderly in Europe are decumulating their wealth and that the average wealth accumulation rate of the retired elderly in Europe is positive though relatively moderate (6.6 percent over a 3-year period). These findings suggest that the Wealth Decumulation Puzzle (the tendency of the retired elderly to not decumulate their wealth or to decumulate their wealth more slowly than expected) applies in the case of Europe. Moreover, our regression results suggest that bequest motives, generous public pension systems, and the reluctance of retired elderly homeowners to sell or borrow against their owner-occupied housing are the primary explanations for the existence of the Wealth Decumulation Puzzle in Europe.     

On the asymptotic behavior of the prices of Asian options

In this paper, we study the price of a long term Asian option the pay-off of which is determined by the average price of the underlying asset during the last fixed number of days of its life. As one can imagine, it converges to the price of a plain vanilla option as the time to maturity increases. We explicitly obtained the asymptotic difference which will be useful for computing the price of Asian option in practice.     

A research agenda for improving national Ecological Footprint accounts

Nation-level Ecological Footprint accounts are currently produced for more than 150 nations, with multiple calculations available for some nations. The data sets that result from these national assessments typically serve as the basis for Footprint calculations at smaller scales, including those for regions, cities, businesses, and individuals. Global Footprint Network's National Footprint Accounts, supported and used by more than 70 major organizations worldwide, contain the most widely used national accounting methodology today. The National Footprint Accounts calculations are undergoing continuous improvement as better data becomes available and new methodologies are developed. In this paper, a community of active Ecological Footprint practitioners and users propose key research priorities for improving national Ecological Footprint accounting. For each of the proposed improvements, we briefly review relevant literature, summarize the current state of debate, and suggest approaches for further development. The research agenda will serve as a reference for a large scale, international research program devoted to furthering the development of national Ecological Footprint accounting methodology.
