The influence of pension funds on corporate governance

Although pension funds have gained importance in the last two decades, their role has not been described in detail by economic models. This article focuses on the scope of these institutional investors when they are not satisfied with a management team of a company in which the pension fund holds a block of shares. Stock holdings by pension funds are largely dispersed. Therefore, any intervention by pension funds in corporate governance requires the formation of a coalition of pension funds. The realization of a coordinated intervention, in turn, is subject to the problems related to the provision of public goods, such as free riding. We find that the stock dispersion and the combined share of pension funds, coordination costs and the attractiveness of the exit option are relevant factors for determining the probability of the success of interventions.     

A critical review of the 2015 South Korean civil service pension reform

The Republic of Korea’s civil service pension (KCSP) was established in 1960 and has been changed several times to overcome the serious financial burdens it has placed on the country. Major problems related to the KCSP include its structure (low contribution and high benefit) and the country’s rapidly aging population. The authors examine the 2015 KCSP reform, reviewing the reasons for the reform, its process, and its fiscal and policy implications. Reforms in other countries are briefly compared. The paper provides important lessons for researchers and practitioners involved in public sector pension reforms.

基于参保时段配比的社会养老保险历史债务估算方法——以2005年基本养老保险制度为基础

社会养老保险的历史债务及其估算一直是学界关注的一个热点问题。本文提出历史债务估算的一种新方法——以“中人”基本养老金为基础、按照其在旧制度的工作年限与新制度下的缴费年限之比确定“中人”历史债务,并以2005年修改的基本养老保险制度为基础建立估算模型。这一方法适合于任一统筹地区。文章还根据某地的实际数据,对该地区的历史债务进行估算。     

Iterated VaR or CTE measures: A false good idea?

The purpose of this paper is twofold. Firstly, we consider different risk measures in order to determine the solvency capital requirement of a pension fund. Secondly, we illustrate the impact of the time horizon of long-term guarantee products on these capital. We consider a financial market modelled by a common Black–Scholes–Merton model. We neglect the mortality and underwriting risks by assuming that the pension fund is fully hedged against these risks, which allows us to keep understandable and tractable formulæ (the longevity risk will be a part of future researches). A portfolio is built in this market according to different strategies and the pension fund offers a fixed guaranteed rate on a certain time horizon. We begin with well-known static risk measures (value at risk and conditional tail expectation measures) and then we consider their natural dynamic generalization. In order to be time consistent, we consider their iterated versions by a backward iterations scheme. Within the dynamic setting, we show that solvency capital can be expensive and that attention must be paid to the safety level considered.
