高校图书馆信息服务中的信息不对称现象及对策

信息不对称理论是微观信息经济学研究的一个核心内容，它普遍存在于社会生活的各个方面，图书馆同样存在着严重的信息不对称问题。本文揭示了图书馆信息服务中存在的几种信息不对称现象，并提出了抑制信息不对称的策略。     

Incentive Contract and Weather Risk

We study contracts designed to remunerate a farmer for the production of an ecosystem service with the payment dependent on the results of the farmer’s actions and on weather conditions. Two contracts are proposed: the first takes into account both the results of the farmer’s actions and a weather variable that reflects the actual atmospheric conditions during the life of the contract; the second bases the payment on the results alone incorporating only the average effect of weather. Social welfare is optimal when both the results and the specific atmospheric conditions are taken into account; however, this type of contract may be less acceptable to the farmer due to his perception of the level of risk involved.We thank two referees for valuable comments.     

员工职业生涯的心理契约的动态管理

员工的职业生涯是一个动态的过程。在这一过程的不同阶段,员工的需求、态度、工作行为都存在着较大的差别,员工与企业之间的心理契约在内容上也会发生变化。而心理契约作为一种隐性契约,具有显著的特殊性,这种特殊性在客观上要求企业对其进行动态管理。本文从职业生涯管理的视角阐述了员工不同职业生涯阶段心理契约的特点以及如何对其进行动态管理。     

Outsourcing, Imports and Labour Demand

This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.

超越契约理论--演化论视角的企业理论研究

企业的契约理论围绕交易成本概念解释了企业的存在、边界和内部组织,但严重忽视了企业的技术和生产功能,演化经济学的企业理论通过研究企业内知识的产生、传播和利用过程,以及组织与个人的交互学习,不仅重新解释了企业的存在、边界和内部组织问题,还研究了契约理论未触及的企业异质性、竞争优势和企业家等问题.     

非审计服务、盈余管理与审计质量——来自中国证券市场的经验证据

本文以2001～2004年A股上市公司为研究对象,在国内首次验证了会计师事务所向审计客户同时提供审计与非审计服务,是否会允许管理当局有较大的盈余操纵空间,以探讨非审计服务的提供是否会影响注册会计师独立审计的质量。实证研究结果显示:在我国,控制了其他影响因素后,非审计服务的提供与异常应计数正相关,但不具有统计显著性。这表明,在我国,没有证据显示,非审计服务会的提供会损害注册会计师审计独立性及审计质量。     

In search of marginal environmental valuations — ecosystem services in Finnish forest accounting

There is currently substantial interest in valuing various services provided by different ecosystems. Concurrently economists have ascribed substantial effort on expanding traditional forest accounting systems by environmental services. This paper contributes to curtailing the existing gap between green accounting theory and applications for valuing forest ecosystem services. The multitude of links between forest ecosystem services and economy are characterized by the theoretical model for forest-economy interactions. By utilizing recently updated data we also incorporate empirical value estimates of these services comparable to other goods into Finnish forest accounting system. Finally, we discuss some problems encountered and clarify the interpretation of some value estimates incorporated to national forest account.     

生态系统服务与生态系统管理研究

生态系统管理的研究是当前生态学研究的热点,生态系统服务(包括生态服务功能的价值评估)是生态系统管理研究的重要部分。本文从笔者的研究实践提出了区域生态系统管理研究的四项主要内容,分析了生态系统服务在生态系统管理研究中的作用,同时阐述了笔者在生态系统服务功能及其价值评估研究中的探索。     

Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.
