Performance Volatility and Wage Elasticity: An Examination of Listed Chinese A-share Enterprises

The management of future financial risk on the part of managers and changes in firm finances are two of the fundamental reasons for upward and downward rigidity of wages. The proxy variable for firm financial risk is volatility, the past performance of which is among the principal indicators of wage rigidity. In firms whose current performance is on the upswing, the greater the volatility in past performance, the smaller the elasticity ratio and the more acute the upward rigidity; the more stable past performance, the larger the elasticity ratio and the more acute the upward elasticity. In firms in which current performance is declining, greater past performance volatility leads to a larger elasticity ratio and more acute downward rigidity, whereas more stable such performance leads to a smaller elasticity ratio and more acute downward rigidity.

Hedge funds and financial stability: Regulating prime brokers will mitigate systemic risks

We review key characteristics of the hedge fund industry, and identify conditions under which this sector can pose a threat to financial stability. Direct regulation of hedge funds that increases transparency does not appear feasible, may create a moral-hazard problem, and may reduce market liquidity. Indirect regulation by prime brokers and market discipline by creditors, counterparties, and investors have been effective in limiting the risks from the hedge fund sector. To reduce systemic risks, more regulation of prime brokers is warranted to avoid competitive dynamics from undermining counterparty risk management practices.     

P2P网络借贷的风险与监管问题分析

近年来,作为金融创新的一种形式,我国P2P网贷平台迅猛发展,在解决资金供需矛盾的同时,也出现一系列负面问题,如跑路、提现困难,甚至诈骗等现象。因此,如何对P2P网贷平台进行风险防范和监管成为当前亟需解决的问题。P2P网络借贷的风险主要表现为:借款人引发的风险;投资人引发的风险;担保人引发的风险;平台引发的风险。对P2P网络借贷进行风险防范和监管的措施应包括:完善相关法律体系,明确法律地位;完善网络借贷行业规则和监管标准;建立完善透明的征信机制;加强网贷平台的行为监管;加强消费者保护和消费者风险教育。

年轻高管与企业股价崩盘风险：来自“代理冲突观”的证据*

在企业纷纷实施高管年轻化战略的背景下,本文从股价崩盘风险的视角分析和检验了年轻高管风险偏好的经济后果及其作用机理。本文基于“个体认知观”和“代理冲突观”展开理论推演,采用中国沪深A股非金融上市公司的数据,检验发现,年轻高管会显著加剧企业未来的股价崩盘风险,且这种影响主要存在于民营企业,在国有企业并不显著。进一步针对具体作用机制的检验发现,年轻高管在投资决策中选择了更多能迅速提升个人收益的风险性投资项目,但在不能迅速提升个人收益的风险性投资项目上与年长高管没有显著差异。同时,年轻高管对股价崩盘风险的加剧效应仅仅存在于高管在上市公司领取薪酬的样本企业,且更高的独立董事比例能显著抑制年轻高管的股价崩盘风险加剧效应。这表明,年轻高管个体认知层面的风险偏好被其追求个人私利最大化的代理冲突所扭曲,进而为年轻高管风险偏好的“代理冲突观”提供了实证证据。     

The Quantitative Analysis on Leverage and its Effects

Leverage of modem enterprise＇s financial management includes operating leverage and financial leverage. Both of them exist objectively, are not changeable with human＇s minds. They enlarge enterprise＇s benefit and risk, so they have both positive and negative effects. The degrees of them are measured as DOL and DFL. In financial management, the relationship between DOL and operating risk has regularity in quantity, and so does the relationship between DFL and financial risk.     

Economic policy uncertainty and firm investment: evidence from the U.S. market

This paper examines the impact of economic policy uncertainty on firm-level capital investment, by not only delving into the long-term investment-uncertainty relation like previous studies, but also analyzing the short-term investment-uncertainty relation for the U.S. market. The empirical investigations show that firms decrease short-term, long-term, and total firm investments when encountering higher economic policy uncertainties. The research also explores the non-linear investment-uncertainty relation based on various theories. Our findings present a U-shaped relationship between short-term, long-term, and total investments and uncertainties. Policy implications are provided from our empirical results.
