契约角度的资本结构优化

企业作为一系列契约的耦合体,在组织形式上表现为通过对企业契约的控制权与剩余索取权的对应配置而形成的治理结构,在广义会计上则表现为企业的资本结构。从资本结构的主要构成内容来看,债券或债务与股票都是规制资本交易的两种契约手段,故从契约角度研究资本结构便日益受到重视。本文在前人研究的基础上,从会计等式的契约属性出发,从而实现契约与资本结构的对接,并在分析股权契约与债务契约的特点和功能的基础上,提出了通过股权契约与债务契约的适度耦合来优化资本结构的新思路。     

人类后基因组研究进展

煤矿安全生产与经济发展

现代安全经济学对安全的重要性有一个很好比喻，即“三角形理论”：经济为两条边，安全是一条底边，没有底边的支撑，形成不了这个三角形。经济发展再快，没有安全就构不成稳定的三角形。可见，安全不仅是人类生存的需要，而且是经济发展的前提。一是安全生产保护生产力。生产力3大要素中，人是最具决定性的因素。人类自有生产活动，便存在事故隐患。安全生产的本质是不断消除隐患、遏制事故，保护劳动者的生命安全健康，所以，安全生产始终是保护生产力的一项不可缺少的工作。二是安全生产发展生产力。生产是一种复杂的物质转换活动，活动过程中会遇到各类事故隐患。安全生产通过排治隐患遏制事故，用尽量少的劳动消耗和物质消耗，生产出更多符合社会需要的产品，来促进生产力的发展。     

Global economy gathering strength

Encouraged by a highly expansionary economic policy, the global economy is enjoying a rapid upturn. Utilisation of capacity is high in many sectors, particularly in the growth centres of the USA and East Asia, where China leads the field. With inflationary risks on the increase, most countries are now shifting the focus of economic policy. Fiscal policy in particular can be expected to provide little in the way of further stimulus. In addition, there has been a turnaround in interest rates in many countries. Yet how quickly can the monetary reins be tightened without jeopardising growth or endangering price stability?     

New ways of achieving debt sustainability beyond the enhanced HIPC Initiative

In 1996 the Heavily Indebted Poor Countries (HIPC) Initiative was launched by the Bretton Woods institutions to reduce the external debt burden of low-income countries (LICs) to sustainable levels in a reasonably short period of time because debt constitutes an obstacle to sustainable economic growth and poverty reduction. In some HIPCs, however, debt sustainability has been in danger despite debt relief under the HIPC Initiative. Debt relief is a necessary but not a sufficient condition for development. It can do no more than play a catalytic role. The question, then, is how to achieve debt sustainability beyond the HIPC Initiative.
