财务会计信息与公司治理

财务会计系统不但给公司控制机制提供直接的财务信息,而且还提供股票价格中反映的所有间接信息。会计治理研究中的一个基本目标是为财务会计提供的信息,在多大程度上减缓由所有权和经营权两权分离所带来的代理问题,以及减少信息不对称问题提供证据。本文着重探讨财务会计信息在公司治理机制中的作用,公司治理机制对财务会计信息反作用的互动研究,并提出了公司治理的对策。

Duration analysis of venture capital staging: A real options perspective

This study takes a real options perspective towards venture capital staging and views the staging decision as a choice between holding the current option to invest and investing now to obtain the option to invest subsequently. It proposes that this staging decision depends on the factors that influence the value of these two options, such as competition and various sources of uncertainty. The empirical results suggest that market uncertainty encourages venture capital firms to delay investing at each round of financing, whereas competition, project-specific uncertainty and agency concerns prompt venture capital firms to invest sooner. This study has useful implications for theory and practice.     

自镇流荧光灯初始光效测量不确定度评定

对自镇流荧光灯初始光效的测量不确定度进行评定,分析了不确定度的主要来源,通过功率测量不确定度分量和初始光通量不确定度分量得到合成不确定度,最后计算出自镇流荧光灯初始光效的测量扩展不确度为1.54 lm/W。为提高自镇流荧光灯初始光效测量的有效性提供了可靠的理论依据。     

DECISION THEORY UNDER AMBIGUITY

Abstract We review recent advances in the field of decision making under uncertainty or ambiguity. We start with a presentation of the general approach to a decision problem under uncertainty, as well as the ‘standard’ Bayesian treatment and issues with this treatment. We present more general approaches (Choquet expected utility, maximin expected utility, smooth ambiguity and so forth) that have been developed in the literature under the name of models of ambiguity sensitive preferences. We draw a distinction between fully subjective models and models incorporating explicitly some information. We review definitions and characterizations of ambiguity aversion in these models. We mention the challenges posed by some of the models presented. We end with a review of part of the experimental literature and applications of these models to economic settings.     

Cultural distance and cross-border bank linkages

This study investigates the effect of cultural distance on global bank linkages using country-pair data for the period 1990–2013. We followed Schwartz (2006) to measure cultural distance, and employed the number of bank pairs involved in cross-border syndicated lending from the source to target countries as a measure of bank linkages. We found that cultural distance has a negative association with bank linkages. This effect is stronger in countries featuring higher informational asymmetries, as represented by weaker institutions, higher uncertainty, or revolution shocks. Our results hold even when employing alternative measures of bank linkages and cultural distance, and when considering the potential endogeneity of cultural distance.
