Abstract: | 本研究的目的是針對退休金的長期負債以資產負債管理的方式提出有效的投資避險策略建議。在過去,傳統精算的資產負債管理大多採用確定投資模型(Deterministic Model),即以過去的經驗設立「精算假設」,但是這樣的假設無法精確的呈現未來的趨勢,所以本文的第一部份,便是根據過去的台灣總體經濟資料,建構一個退休基金的隨機投資模型(Stochastic Investment Model)。首先,我們以ECM(Error Correlation Model)模式建構出第一個投資模型,之後在精簡參數的考量下,建構第二個以因果關係為基礎的Causality投資模型,再以模型配適能力與預測能力比較兩模型,結果顯示Causality投資模型優於ECM投資模型。
有了投資模型,我們設定不同的退休金負債形式,如固定成長型負債MF、隨通貨膨脹成長M<sup>R</sup>負債及隨max{固定成長比例,通貨膨脹}而成長的退休金負債M<sup>L</sup>,以靜態避險的方式去求得各資產的最適配適比例。從模擬的結果中發現隨著到期日的增長,投資在風險性高報酬率佳的投資標的物上的比例也越來越高。另外,隨著負債固定成長比例f的增加,其M<sup>L</sup>負債之期初資產配置額便越接近M<sup>F</sup>負債之期初資產配置額。整體而言,我們由模擬中可得出,使用投資組合的投資方式優於單一資產投資的結論。 In this study, we investigate the hedging strategies for pension liabilities by using Asset-Liability Management method. In the past, the traditional actuarial valuation usually does not take account of market value for both assets and liabilities. Most of the traditional actuarial valuation adopted the Deterministic Model, that is, setting the assumptions based on the experiences. However, it can not exactly show the trend in the future. In part one of this study, we build a stochastic investment model for the pension funds based on Taiwan Market data. First, we apply the first model : ECM( Error Correlation Model ). And then, we apply the second model : Causality Model under considering parsimonious parameterization. Finally, we compare the results of ECM with Causality Model on fitting and forecasting efficiency, and we find that Causality Model is better than ECM. With the investment model, we set some formulas of pension liabilities calculated to obtain the best fit proportion of each valuation by the static hedging. This involves finding optimal static hedging strategies to minimize riskiness of the investment portfolio relative to the liability. Overall, from the simulation results, for static hedging in these kinds of liabilities, investing in all three assets is a better strategy than investing in a single asset class. This confirms that the more assets we use, the more effectively we can hedge. |
