No. of bitstreams: 0 Previous issue date: 2001 / o trabalho discute os fatores que condicionaram a migração de planos de beneficios entre os Fundos de Pensão localizados no Estado do Espírito Santo. O mais antigo modelo de plano de beneficios implantado no Brasil, o plano de beneficio definido, tem características bastante vantajosas aos participantes, pois as empresas patrocinadoras assumem os riscos de desequilíbrio do plano, e os beneficios futuros são assegurados aos participantes. O segundo modelo, mais recente no país, tem como característica principal o fato de que o participante assume os riscos do plano, e os beneficios futuros dependem de diversos fatores, como rentabilidade, tempo de participação, entre outros, deixando de existir garantia aos participantes. Apesar disso, os Fundos de Pensão tem implantado processos de migração de planos de beneficio definido para contribuição definida com sucesso. O texto procura identificar as razões e conseqüências da migração, estabelecendo correlações entre os dois modelos, identificando suas diferenças e semelhanças, o papel exercido pelas empresas patrocinadoras e a estratégia de convencimento dos participantes. Pretende-se que as reflexões sobre esse processo possam contribuir para que os Fundos de Pensão e outros pesquisadores interessados possam ter um nível maior de compreensão e fundamentação sobre o assunto. / This dissertation discusses the factors that have created the framework for the migration of the pension plans among the pension funds in the state of Espirito Santo. The first benefit plan model in Brazil, the defined benefit plan, has many advantages for the participant. Their risks are supported by the sponsor of the plan, and future benefits are assured to the participants. The second model, more recently introduced in the country, has its main point in the fact that participants have to bear the risks, and future benefits depend on many factors like the historical performance of the plan and time of participation, and there is no guaranty to the participants. Regardless these facts, pension funds have adopted successful processes for the migration from defined benefits plans to defined contribution plans. This text identifies reasons and consequences of those process of migration, establishing correlations, differences and similarities between the two models, and the role of the sponsors and their strategies in persuading the participants. We intend to raise questions upon this process, in order to contribute for a greater levei of comprehension of the issue.

近年來有很多關於退休金計畫的研究主要在探討從確定給付計畫(defined benefit plan)轉向確定提撥計畫(defined contribution plan)趨勢的影響。而這些早期的研究(Clark and McDermed(1990 and 1993), Gustman and Steinmeier(1992), Ippolito(1985, 1986, 1993, and 1997), and Kruse (1995); Papke(1994, 1996)and Papke, Petersen and Poterba(1996)主要是利用計畫個數的改變或者是計畫參與者人數的增減來作為衡量此一趨勢影響力的指標。然而，這兩項指標從退休收入多寡的觀點來看，卻無法反應此一趨勢對於員工福利的影響程度。Wang andVanDerhei(2000)利用了「雇主退休金成本」的新概念，探討此一趨勢的影響。而本篇論文將要延續Wang and VanDerhei(2000)的研究，藉由衡量雇主慷慨程度的改變，進一步分析此一趨勢對於員工未來退休收入的影響程度。為了檢視雇主退休金慷慨度是否有隨著時間以及環境變化而有所不同，我們利用OLS迴歸模型來分析在兩段期問中（1985年與1996年）雇主退休金慷慨度的變化。結果發現在確定給付計畫及401(k)計畫之下，退休金計畫存在的時間愈長以及工會的支持對於雇主慷慨程度都有正面的影響。在財務變數方面，我們則是發現不論哪一種型態的退休金計畫，稅前收入金額的多寡對於雇主慷慨程度均具有正面的影響。此外，利用Chow Test，我們發現確定給付計畫在1985年和1996年的確具有結構上的改變，進一步分析之後，發現退休金計畫存在時間愈長、工會的支持、金融相關產業、固定資產佔總資產的比例以及稅前收入金額的多寡對於1996年確定給付計畫下之雇主退休金慷凱度的正向影響遠大其對於1985年的確定給付計畫。在員工退休福利上，我們則是發現401(k)計畫的雇主相對提撥率在過去20年有明顯地成長，這意味著401(k)計畫下的員工在過去20年裡的退休福利有明顯的增加。 關鍵字：退休金趨勢、雇主退休金慷慨度、確定給付計畫、確定提撥計畫、401(k)計畫 / Much debate has devoted in recent pension literature to discuss the impacts of current pension trend toward defined contribution(DC) plans, especially the substitution effect between 401(k) and other pension plans. However, the“generosity”of the employer pension plan deserves little attention. This paper analyzes the impacts of the effects of this trend on workers' future retirement income by measuring the changes of employers' pension generosity. We construct a panel data of firms that sponsor at least one pension plan in 1985 and compare the changes of their pension generosity for DB, DC and 401(k) plans between 1985 and 1996. OLS Regression Models are adopted to analyze the generosity of employers' primary plan and supplemental plan and Chow test is conducted to test the structural changes between 1985 and 1996. Our results find that plan age and union status have positive impacts on employers' generosity ofDB and 401(k) plans. For financial variables, pretax income is an important consideration to employers' generosity disregarding the type of plan. In addition, we find that there was a structure change ofDB plans between 1985 and 1996 and that union status,plan age, financial etc. industry, proportion of fixed assets and pretax income have greater positive impacts on employers' generosity ofDB plans in 1996 than in 1985. For employees' retirement income, the matching rates have grown over the last two decades and this stands for that employees covered by 401(k) plans have received better retirement benefit over the last two decades. Key words: Pension trends; Employers' generosity; Defined benefit plan; Defined contribution plan; 401(k) plan

員工持股計畫是由財經律師Louis Kelso所創，在美國已行之多年，廣為美國企業所採。最早的員工持股計畫是一種為了和平地從資本家手中移轉資本給員工、縮減貧富差距的工具。為了使這個計畫可以持續有效地運作下去，立法者將員工持股計畫為退休金計畫的一種，使員工必須長期持有股票，直到退休。然而在實務運作上，員工持股信託經常被運用為防止敵意併購的工具。尤有甚者，某些公司內部人會利用員工持股計畫為自己取得大量資金、移轉投資風險,但仍可保留對於公司的控制力。這些行為都有可能對股東及員工造成不利的影響，但在現行法制下，只能仰賴司法者透過判決保護這些經濟及資訊上的弱勢族群。 在台灣，員工持股計畫雖然已廣為許多企業所採用，但是發展了將近20年，只能成為另一種員工持有股票的工具。員工擁有的股票數量並不足以使其在股東會上贏得一個受公司內部人重視的地位，也不足以倚賴這些股票作為退休金之用。這種規模上的差異是台美員工持股計畫最關鍵的不同點。小規模雖然使員工持股計畫帶來的優勢少了許多，但相對地也減低許多代理成本，至今未有員工持股計畫侵害大量員工利益的事件爆發。然而這不表示員工持股計畫在台灣就是個可以被忽略的問題，若能在未來建立一套有效率的立法制度，使員工持股計畫的規模擴大，員工將可因此享受到更多公司盈餘，並且使其退休生活受到保障。相對地，參考美國員工持股計畫的問題後，也可以預先設想未來可能發生的弊端，未雨綢繆。本文相信，一個有效率的員工持股計畫，可以實現解決貧富不均的理想。 / Employee stock ownership plan (ESOP) which is created by Louis Kelso is brought to practice for many years. Many enterprises use it as their retirement pension plan. The earliest employee stock ownership plan to transfer the capital frome capitalists to labors and reduce the disparity between the rich and the poor.In order to make the plan work out continueously and effectively, the legislator devise ESOP as a pension fund which makes employee own stock chronically until they retires. However, in practice, ESOP is usually exercised for preventing hostile takeover. Moreover, some company insiders may use ESOP TTO get a great deal of capital and transfer the investment risk, but still own the controlling power to their company. This behaviors will cause some harmful effects to the shareholders and the employees, but in the current legal system,the only one we can depend is the judge who can protect the minority in the economic and the information. ESOP is exercised by many enterprises in Taiwan. But after 20 years, it can only become one of the tools which assist employees to acquire company stocks.The number of shares which employees owns can’t make them have a posi-tion which let the company insiders take account in the shareholder committee and have enough amounts for their retirement pensions.This disparity in scale is the keypoint what is different between Tiwan and the U.S. ESOP. Althoygh small scale makes the adventage of ESOP decrease, it reduce lots of agency costs. To this day, there’re not any events which injure the interests of employees by ESOP. Never-theless, it doesn’t mean that ESOP in Taiwan is a issue which can be neglected. If we can establish an efficient legal system and extend the scale of ESOP, employees can obtain more company interests and have a security of their retirement life.In the opposite, after researching the problem of the U.S. ESOP, we can assume the culpably misconduct which will happen in the future and repair the house before it rains。Ｉ believe that a efficient ESOP can realize the ideal to solve the problem of uneven distribution of the wealth.
