经营者集中附条件批准下的待剥离资产处置

经营者集中附条件批准又被称为合并救济,其目的是在维护市场有效竞争与维护企业健康发展之间寻求平衡。资产剥离是最为重要的合并救济措施。在等待资产被最终剥离的过渡期内,适当处置待剥离资产,保持其竞争力,对于合并救济目的之实现非常关键。我国应进一步细化资产剥离制度,而执法部门则应结合个案需求,提出一般资产保值甚至资产分持的资产处置要求,来确保待剥离资产的竞争力。

公司股权结构对公司治理绩效影响的实证研究——以深圳证券交易所上市公司为例

用多变量分析检验公司股权结构对公司治理绩效的影响,会得出如下结论:1.大股东持股比例与企业绩效指标托宾q之间存在曲线关系,支持权衡理论(Trade-off theory)。2.托宾q值和第二到第五大股东持股集中度、代表机构投资者的基金比例表示显著正关联,非控股股东的持股比例与企业价值水平正相关,但是大股东持股比例集中度在45%左右,非控股股东不能有效地发挥监督大股东的作用,大股东有绝对权利控制公司。     

日本外汇资金特别会计及财务报表评析

金融危机后,在学术界普遍主张减持美国国债和中国政府时增时减的背景下,日本却稳定采取增持美国国债战略,日本外汇储备形成和管理机制、外汇资金特别会计的制度设计及其财务报表的特征有助于解释这一现象,研究发现日本外汇资金特别会计中投资收益的存在是日本政府不断增加外汇储备和投资美国国债的重要政策依据。首先分析日本外汇储备的形成及其管理机制,发现外汇资金特别会计在其中发挥着重要作用,其次分析日本外汇资金特别会计及财务报表状况,把握巨额投资收益形成的原因,最后分析日本外汇资金特别会计存在的问题及近年来的改革措施。

Multistate modeling of clinical hold in randomized clinical trials

A clinical hold order by the Food and Drug Administration (FDA) to the sponsor of a clinical trial is a measure to delay a proposed or to suspend an ongoing clinical investigation. The phase III clinical trial START serves as motivating data example to explore implications and potential statistical approaches for a trial continuing after a clinical hold is lifted. In spite of a modified intention‐to‐treat (ITT) analysis introduced to account for the clinical hold by excluding patients potentially affected most by the clinical hold, results of the trial did not show a significant improvement of overall survival duration, and the question remains whether the negative result was an effect of the clinical hold. In this paper, we propose a multistate model incorporating the clinical hold as well as disease progression as intermediate events to investigate the impact of the clinical hold on the treatment effect. Moreover, we consider a simple counterfactual censoring approach as alternative strategy to the modified ITT analysis to deal with a clinical hold. Using a realistic simulation study informed by the START data and with a design based on our multistate model, we show that the modified ITT analysis used in the START trial was reasonable. However, the censoring approach will be shown to have some benefits in terms of power and flexibility.     

Unobservable Investment and the Hold‐Up Problem

We study a two‐person bargaining problem in which the buyer may invest and increase his valuation of the object before bargaining. We show that if all offers are made by the seller and the time between offers is small, then the buyer invests efficiently and the seller extracts all of the surplus. Hence, bargaining with frequently repeated offers remedies the hold‐up problem even when the agent who makes the relation‐specific investment has no bargaining power and contracting is not possible. We consider alternative formulations with uncertain gains from trade or two‐sided investment.
