The asymmetry in firms’ mechanisms of cash holdings adjustments: evidence from the G-5 economies

Review of Quantitative Finance and Accounting - Using a G-5 country sample (France, Germany, Japan, the UK, and the US) from 1980 to 2007, I find new evidence of the asymmetry in firms’...     

Investment, uncertainty and irreversibility

This paper investigates the irreversibility of investments and the impact this has on the nature of the relationship between investment and uncertainty. The empirical analysis uses firm‐level data and is based on a survey of 210 rice‐milling firms in the Mekong River Delta in Vietnam, which was carried out during the year 2000. We show that uncertainty reduces investment of rice millers in the presence of irreversibility, as is predicted by the real options approach to investment. We do not find evidence that the negative association between uncertainty and investment is influenced by the degree of irreversibility.     

A note on measuring political participation in comparative research

This article presents an application of Prezeworski and Teune's so-called “identity-equivalence method” to a large set of indicators of political participation. By relaxing commonly held assumptions about necessary distinctions among types of participation, it is found that the distinction between “conventional” and “unconventional” modes of participation is unnecessary, while the distinction between “government” and “nongovernment” has some merit. The findings also lend further support to the claims of Prezeworski and Teune that the identity-equivalence method is preferable to the identical indicator method.     

Socially Responsible Investing and Climate Change: Contradictions and Challenges

This article explores the contradiction between the articulated investment policies, screening criteria or ethical charters of socially responsible investment funds and their actions demonstrated by their portfolio selection practice. The paper provides a background to socially responsible investment and Australia's contribution to greenhouse gas emissions. A discussion of renewable energy options lays the foundation for our main assertion: that this set of possible alternatives provides some new and more environmentally robust options that will better complement the underlying philosophy of funds in the socially responsible investment sector.     

Migration consequences of welfare reform

We investigate whether recent changes in welfare policy affect the migration of low-educated unmarried mothers. Estimates indicate that welfare reform is associated with an increase in employment-related intrastate migration, and a decrease in non-employment related migration, both within and between states. The net effect was a small increase in intrastate migration and a small decrease in interstate migration. The close link between migration and employment suggests that welfare reform has motivated low-income women to move for economic reasons. In general, welfare policy appears to have a much larger effect on residential location because of its relationship to employment than because of benefit differences between states.     

中国农业银行多业务光纤城域网建设

城域网是与局域网和广域网相对应的计算机网络的概念，数据通信和电信技术的发展赋予城域网新的内涵，将城域网的概念延伸到整个通信网络，泛指在城市及其郊区范围内提供多种业务的所有网络。城域网覆盖大约2公里到150公里的范围，是城市中作为局域网互连的高速网络，它以宽带光传输为开放平台。各个城市的城域网最终将透过更大范围的广域网络骨干相互衔接，最终形成一个全国或全世界规模的无所不在的网络。
