How Owners Matter? An Examination of Ownership Type in Corporate Disaster Relief Giving

Little research has investigated the effect of ownership identity (or type) and corporate philanthropy experience on giving. In this research, relying on legitimacy theory, we first assess the effect of ownership identity on corporate philanthropy (CP) in the context of the 2008 earthquake in China. Then we explore moderation effects of firms' prior CP experience and size as proxies for perceived legitimacy on owners' efforts at increasing giving and legitimacy. We find that state and CEO ownership are deterrents, while non‐SOE and institutional ownership enhances giving probability and amount. In addition, there is evidence that firm size and prior CP weaken the effects of institutional ownership on CP. This study provides a complete assessment of owner behaviour. Copyright © 2018 ASAC.

Idiosyncratic Information,Moral Hazard,and the Cost of Capital

This paper examines the effects of idiosyncratic accounting information on a firm's cost of capital. By embedding a moral hazard problem into a multifirm asset‐pricing model, I show that moral hazard distorts the sharing of idiosyncratic risk but does not affect the sharing of systematic risk in the economy. A firm‐level improvement in idiosyncratic information reduces the firm's cost of capital even though it does not affect the implied cost of capital inferred from publicly traded shares. Moreover, an economy‐level improvement in idiosyncratic information reduces the risk premium for idiosyncratic risk but increases the risk premium for systematic risk, resulting in an ambiguous net effect on the firm's cost of capital. These results provide alternative explanations for the mixed empirical evidence on the relation between information quality and the cost of capital.

Sustainable Development and Management of Water Resources in the Hei River Basin of North-west China

The quantitative and qualitative evaluation of water, land and biotic resources in the inland river basins is important in the arid zone. Analysis of the exploitation potential of water resources and the environmental changes through water development can help people in the sustainable development and management of water resources within the basin. Water resources development has affected the scale of oasis establishment in the middle reaches and the existence of lower-reach oases in the Hei River basin. Exploitation and utilization of water resources at the present stage should bring about a harmonic relation between economic development and the ecological environment in the whole basin. The whole area should be considered as an entirety to adopt feasible engineering and administrative measures such as strengthening the protection of water resources in upper streams, macro-control of water consumption and implementing water-saving measures in middle and lower reaches, quantitatively managing and allotting water resources in accordance with regional conditions and adherence to comprehensive rehabilitation. Thus, economic, environmental and social benefits of water resources can be enhanced.     

发展中国远期外汇品种的优先次序

中国人民银行宣布自2005年7月21日起中国开始实行以市场供求为基础、参考一篮子货币进行调节、有管理的浮动汇率制度。这是中国在汇率形成机制市场化改革进程中迈出的重要的关键一步,这表明人民币汇率的变动将更加灵活、具有弹性。此后不久,央行在8月10日推出促进银行间外汇市场发展的重大举措,其中包括扩大即期外汇市场交易主体、允许开办银行间远期外汇交易、并允许符合资格的市场会员开展人民币掉期交易等。这意味着,在新的汇率制度下,政府正加快发展完善远期外汇市场的步伐,从而为市场主体提供更充分、有效的避险工具,避免汇率变动对实…
