基于协同平台的高校教师科研绩效评价体系

在研究组织人员行为绩效评价体系的基础上,分析了传统的KPI(key performance indicator)评价方式所面临的主要问题,提出针对高校教师科研绩效进行分类建模,并设计相应的绩效指标、绩效算法及评价体系来解决问题。最后,用某院教职工2015—2019年在协同信息管理平台上的行为数据,检验了该体系的有效性及合理性,并针对基于协同平台的高校教师科研绩效评价体系的结果分析,提出高校科研管理及绩效激励方案。     

Corporate Lobbying and Firm Performance

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation.     

Do Sovereign Re‐Ratings Destabilize Equity Markets during Financial Crises? New Evidence from Higher Return Moments

This study investigates the effects of S&P's sovereign re‐ratings on the higher moments of equity market returns over recent financial crises. Using a set of intraday stock market index prices and sovereign credit ratings for a sample of 36 countries that experienced sovereign rating changes over the period from 1996 to 2013, we find that the higher moments of stock market returns are significantly more responsive to sovereign re‐ratings during financial crises, but the effects on stock markets are not the same across different financial crises. The effects during crises are, however, magnified for large downgrades and those that are associated with a loss of investment grade status. We find that there are asymmetric effects during financial crises in that downgrades are consistently more significant than upgrades in increasing realized volatility and realized kurtosis. Both upgrades and downgrades affect realized skewness in times of crises in the expected direction.     

On post-IPO stock price performance: A comparative analysis of RLBOs and IPOs

This is the first study to examine the post-IPO stock price performance by differentiating between IPOs and three types of RLBOs (i.e. public-to-private (or re-IPOs), division-to-private, and private-to-private deals). We document that public-to-private RLBOs outperform their industry rivals, IPOs, mature firms in comparable industries, and a propensity-score matched control group for up to five years post-offering. Further, we document that, within RLBOs, public-to-private RLBOs, outperform private-to-private and division-to-private RLBOs. We also find support for the underwriter signaling effect for public-to-private RLBOs. Our analysis identifies for the first time what private period restructuring activities contribute to superior post-re-IPO stock price performance. Further, the beneficial effects of private period restructurings are enhanced for deals associated with prestigious underwriters. Our findings suggest that first IPOs and re-IPOs differ substantially in term of post-offer performance, the impact of prestigious underwriters on performance, and performance over time.

我国水果产品在东盟市场的竞争力研究

运用市场占有率、贸易竞争力指数、显性比较优势指数对我国与东盟主要水果出口国在东盟市场的竞争状况进行了测算和比较分析。研究结果表明:在总体上,我国水果在东盟市场上具有一定优势,但在多数水果品目上并不具有竞争优势;研究结论可为有针对性地增强我国水果在东盟的竞争力提供借鉴。     

证券市场监管理论——公共利益论、部门利益论的比较与评述

对经典的监管理论,尤其是对公共利益论、部门利益论与捕获论形成的背景、内涵、优缺点、适用条件进行了完整的比较分析,认为这些理论观点对监管的研究和监管实践有着重要的指导意义,但每一种理论都是对监管的某一方面进行的研究,还没有一种理论能够对证券市场监管的所有问题做出满意的解释。要提高我国证券市场监管的效果,需要从整体上运用这...     

对价方式、盈余管理与市场绩效

选取国有企业控制权转移的样本,剖析有偿转让和无偿转让这两种不同对价方式对盈余管理的影响,并对不同的对价方式下控制权转移是否改进了企业的中短期及长期的市场绩效进行经验检验。研究发现：（1）有偿转让控制权的对价方式更易推动上市公司通过操控应计利润调低净资产,提高溢价率,以符合政策要求;（2）在整体上无偿类样本相对于同行业公...

数字偏好与股票收益异常——来自上海证券交易所的经验证据

本文研究股票代码对股票收益的影响。研究发现,由于数字偏好效应的存在,投资者刻意回避代码以“4”结尾的股票。在较长时间内,尾数是“4”的股票收益低于给定风险水平下的市场必要收益。但这一现象受到股市行情的影响,牛市行情时,投资者回避“4”的行为表现明显,而熊市行情时则会趋向消失。具体表现为：牛市行情下,“4”组合的资产收益小于给定风险水平下的市场必要收益,熊市行情则无此现象。本文从行为金融莹晶当磨时杖一仑蜃由市扬耳夔讲符T觎崧
