基于循环经济的环境财务分析指标体系构建

目前我国的经济增长与自然环境之间的矛盾十分突出,需要大力发展循环经济,而建立环境财务分析指标体系,有助于推动企业循环经济的发展。本文介绍了循环经济的基本理论,简要回顾了国内外关于循环经济的理论研究成果。在此基础上,分析了循环经济对传统财务分析指标的影响,主要体现在主体多元化、目标多元化和指标多样化上。并根据3R原则设计了若干环境财务分析指标,指出了这些指标在沃尔评分法中的应用。     

DEALING WITH UNCERTAINTY: ROBUST RULES IN MONETARY POLICY

We argue that in seeking to insure against model uncertainty, monetary policy makers are often ready to trade ex post performance for greater certainty in the outcome. They thus look for rules that although not optimal ex post, have certain properties that qualify them as robust. We apply first, Gul's approach of ‘disappointment’ aversion to describe policy makers' aversion to uncertainty and then define the properties the notion of ‘robustness’ entails. With these two tools we then link the desirability of such robust rules to the degree of policy makers' aversion to uncertainty. We thus show that provided such robust rules exist, a larger degree of disappointment aversion leads to a greater emphasis on robustness in policy implementation.     

Earnings Quality under Rules‐ versus Principles‐based Accounting Standards: A Test of the Skinner Hypothesis / LA QUALITÉ DES RÉSULTATS SELON QUE LES NORMES COMPTABLES SONT AXÉES SUR LES RÈGLES OU SUR LES PRINCIPES: VÉRIFICATION DE L'HYPOTHÈSE DE SKINNER*

We provide preliminary evidence, consistent with Skinner (1995), that Canada's relatively principles‐based GAAP yield higher accrual quality than the United States' relatively rules‐based GAAP. These results stem from a comparison of the Dechow‐Dichev (2002) measure of accrual quality for cross‐listed Canadian firms reporting under both Canadian and U.S. GAAP. However, we document lower accrual quality for Canadian firms reporting under U.S. GAAP than for U.S. firms, which are subject to stronger U.S. oversight, reporting under U.S. GAAP. The latter results suggest that stronger U.S. oversight compensates for inferior accrual quality associated with rules‐based GAAP. Consistent with the positive effect of Canada's principles‐based GAAP and the offsetting negative effect of Canada's weaker oversight, we find no overall difference in accrual quality between Canadian firms reporting under Canadian GAAP and U.S. firms reporting under U.S. GAAP. Our results imply that (1) policymakers who wish to compare the effectiveness of oversight across jurisdictions must control for the GAAP effect; and (2) accounting standard‐setters who wish to compare the effectiveness of principles‐ versus rules‐based GAAP must control for oversight strength.     

我国综合性通货膨胀的预期与治理

本文以市场经济下的货币流通理论为指导,构建了我国自改革开放以来的通货膨胀模型,并采用计量经济学的一系列方法对模型进行了检验,实证结果表明：通货膨胀与消费、投资、财政赤字和制度转型等多个变量之间存在协整关系,但各变量对通货膨胀的贡献度具有明显差异,这为中央银行和政府部门采取差别性的宏观调控政策提供了有力依据。     

Stability and change in management accounting over time—A century or so of evidence from Guinness

In recent years, much has been written on the nature of management accounting change, and indeed stability. Many researchers have used concepts such as rules and routines to interpret this change and/or stability. Recent research has provided an increasingly clear picture of what rules and routines are, as well as contributing to our understanding of the processes of change and stability in management accounting.Management accounting research has mainly presented rules and routines as related phenomena, but some conceptual work has suggested they are separable and can (and possibly should) be considered independently when studying processes of change/stability within management accounting. However, empirical support for such work has been scarce to date. This paper uses data from the archival records of the Guinness company in an effort to establish whether rules and routines, at least in management accounting research, are best considered separable concepts or not. The archival records are artefacts of rules and routines and thus can be used to trace the interactions of rules and routines over time. Support for the notion that rules and routines should be considered separately is presented. The findings also portray the stable, but changing, nature of management accounting routines over time; a point worthy of further research.     

The cost of deviating from the optimal monetary policy: A panel VAR analysis

Exploiting the panel VAR GMM estimator's features, macroeconomic country factors are combined with micro-economic bank data to test for the risk taking channel in the Euro Area. According to prior expectations based on an extended DSGE model, the analysis demonstrates that the monetary policy incentives bank risk taking by increasing the bank leverage, but it is not able to influence the level of credit risk. However, deeper investigations indicates the Taylor gap adds to the bank risk appetite in all its forms, while regarding the reactions to target variables, movements in the interest rate smooth the bank risk.     

Regulations for the Eighth International Congress of Actuaries

Abstract

The present paper proposes and investigates a procedure for numerical evaluation of the transition probabilities for a time-inhomogeneous Markov process when the intensities are known (estimated). The procedure is based on Taylor-expansion of the transition probabilities linked with the Chapman-Kolmogorov equations.

WTO《原产地规则协议》对贸易的影响

多边贸易体制中的"原产国标记"与乌拉圭回合《原产地规则协议》对用于海关贸易统计的一般原产地规则做出了原则性规定,但对优惠原产地方面却没有制订出为世界各国所接受的多边规定,致使优惠原产地规则被滥用,对世界贸易产生不均衡性影响。我国原产地规则领域存在的问题突出表现为立法滞后、法规不周详不健全;出口货物原产地授予标准过宽,致使原产地规则不具备宏观调控和投资结构政策导向功能;进口商品原产地认定标准过宽,危害我国幼稚产业的健康发展等方面,导致我国加工贸易减少,对我国吸引外商投资的环境改善将产生不利影响。
