초록

기대수명의 증가와 조기 은퇴의 확산 등으로 인하여 점차 은퇴 기간이 길어짐에 따라 은퇴 자금 축적 및 증식 못지않게 은퇴자금을 어떻게 관리하여 자금의 고갈 없이 은퇴 생활비를 조달할 것인가가 중요한 문제로 자리 잡고 있다. 본 연구는 개인 소비자의 은퇴설계에서 연금화 관련 의사결정에 심리적인 편향 중 하나인 닻 내리기(Anchoring)가 영향을 미칠 수 있을 것인지 살펴보고자 하였다. 서울 및 수도권에 거주하고 있는 40대 남녀 806명을 대상으로 실험 조작을 포함한 온라인 설문을 실시한 결과, 연금화 의사결정에 닻 내리기가 영향을 미칠 수 있음이 나타났다. 본 연구에서는 연금화와 관련된 주요 이슈 중 하나인 연금화 비중에 대하여 살펴보았는데, 이를 은퇴이후 개인이 희망하는 은퇴생활비의 몇 %를 연금으로 수령 받고자 하는가에 대한 연금수령 프레임과 은퇴자금의 몇 %를 연금에 가입할 것인가에 대한 연금가입 프레임으로 나누어서 살펴보았다. 또한, 닻을 제공하는 자를 전문가와 일반인으로 나누어서 제시하여 닻 제공자의 신빙성에 따른 차이를 살펴보고자 하였으며 닻 수준을 큰 수(높은 수준 닻)와 작은 수(낮은 수준 닻)로 나누어서 닻 내리기효과를 파악하고자 하였다. 연구의 결과 연금수령 프레임과 연금가입 프레임 모두 닻 내리기 효과를 발견할 수 있었다. 또한, 다른 변수를 통제한 상황에서도 닻 내리기 효과가 나타나는지를 보기 위하여 회귀분석을 실시한 결과 연금수령 및 연금가입 비중에 닻 내리기가 중요한 영향을 미치는 변수로 나타났다. 본 연구의 결과는 개인의 심리적인 편향 중 하나인 닻 내리기가 은퇴재무설계에서 유용하게 활용될 수 있는 특성임을 시사한다.

Considering the current demographic trends in Korea, retirement planning is one of the most significant issues for the well-being of individuals and families in their later lives. Due to the elongated life expectancy, longevity risk has been the key issue in retirement planning. Therefore, managing retirement asset has been equally as or more significant than preparing retirement asset, because asset depletion is one of the major threat that retirees confront during retirement. So far retirement asset management research has been conducted under the topics of portfolio management and retirement asset withdrawal strategies(e.g., Blanchett, Kowara, & Chen, 2012; Dybvig & Liu, 2010; Horneff et. al, 2010; Milevsky & Robinson, 2005). Several research has been examined the annuitization strategies and annuitization decision making for consumers (e.g., Milevsky & Young, 2007). Annuitization can be explained as a process in which a retiree converts his or her retirement asset into a periodic payment to cover his or her living expenses during retirement years. To properly hedge the longevity risk, consumers need to consider annuitization of their retirement asset.
Annuitization decision making is not an easy task for consumers. There could be various factors that influence annuitization decision making. This research tries to examine one of the factors that could influence consumers' annuitization decision making process, the psychological factor called anchoring. Anchoring is a psychological heuristic or bias in human decision making. Anchoring effect refers to the influences of anchor(or an initial information) on human judgement. Consumers normally are influenced by some initial information on their decision making even though the initial information is un-related to the decision making issue. Previous research has shown that anchoring effect are present in financial decision making(e.g., Epley & Gilovich, 2005; McEloy & Dowd, 2007; Yudkowsky, 2006). However, no research has been conducted to examine anchoring effect in annuitization decision making.The purpose of this research was to examine anchoring effect in annuitization decision especially with the desired annuity amount in retirement income and annuitizaiton ratio out of retirement asset. A survey with 806 respondents in their 40s who are living in Seoul metropolitan area was conducted during February of 2013. The annuitization decision was divided into two different frames: annuity amount and annuitization ratio frames. Respondents who were assigned annuity amount frame were asked to answer their desired annuity amount in retirement income (living expenses). Respondents who were assigned annuitization ratio were asked to answer their desired annuitization amount(i.e. amount to use in purchasing life annuity products) out of the retirement asset that they prepared until retirement. Each frame included four anchors and one neutral question. The four anchors were professional high anchor, peer high anchor, professional low anchor, and peer low anchor. As such this research was designed to examine anchoring effects on high and low anchors and professional and peer anchors. Each respondent was randomly assigned to be exposed to one of the anchors or the neutral question. To examine the anchoring effect the Anchoring Index as presented in Jacowitz and Kahneman(1995) was calculated. In addition, standardized measures to the neutral questions were also calculated. To test the anchoring effects descriptive analyses were conducted as well as Mann-Whitney test. In addition, step-wise regression was conducted to examine related factors to annuitization decision.
The findings showed that there were possible anchoring effects on annuitization decision making. Those who were exposed to high anchors showed higher levels of annuitization intention and those who were exposed to low anchors showed lower levels of annuitization intention than the neutral respondents. The professional anchors had stronger effects than peer anchors in annuitization ratio frame only. Therefore, the effects of anchoring source should be further examined.
These findings provide several implications for practice and research. As suggested in the previous literature, anchoring is one of the strongest human bias in decision making and is hard to overcome. However, anchoring can be used effectively in consumer decision making. The findings from this research showed that in practice, anchoring can be used to educate and guide consumer decision. As mentioned above, annuitization decision making is one of the most important and difficult decision making in retirement planning. By effectively using psychological characteristics of consumers, professionals and educators can better help consumer in retirement decision making. Future research on behavioral finance topics with retirement planning is needed to further develop literature in this area. This research can provide useful insights in annuitization decision making with behavioral finance topics.
