This study examined the effects of ambiguity aversion on the self-protection and self-insurance efforts using a two-period model to consider the time difference between making an effort and occurring loss, which is in contrast with the existing one-period model. The loss follows a binary distribution while the distribution is ambiguous. The distribution depends on the state variable. First, the effort of ambiguity averse individuals is not always greater than that of ambiguity neutral ones. Second, the effects of absolute ambiguity aversion (AAA), which does not appear in one-period model, were observed. Not-increasing AAA is a sufficient condition to increase the efforts of ambiguity averse individuals compared to those of ambiguity neutral ones. In addition, the change in effort also depends on the probability function of the state. Lastly, the results hold even when the individual is risk neutral or risk loving. As a result, ambiguity aversion needs to be considered independently with risk aversion.

This study examined the effects of risk aversion on the Self-Insurance-cum-Protection activity (SICP) in a two period model, which is in contrast to existing studies that focused on an one period model. The assumption that there is a time difference between making an effort and incurring loss helps examine the effects of risk aversion in the long-term period. An increase in risk aversion always increases the efforts of SICP, whereas existing studies require additional restrictions to both the loss and cost function. Second, an increase in risk aversion always increases the efforts on self-insurance and self-protection. This result is in contrast to that of existing studies in that an increase in risk aversion increases the efforts of self-insurance, whereas the effects on the efforts of self-protection are unclear. Lastly, when there exists a background risk with zero mean and risk aversion increases in a two period model, the prudence condition of the utility function is a sufficient condition to increase the efforts of SICP.

This study aimed to investigate the differential effects of individual's cultural disposition (individualism-collectivism or horizontal-vertical thinking) and need for cognitive closure(NFC) on framing effects. For this purpose, the participants were divided into 4 different cultural disposition groups based on Singelis et al.'s[1] INDCOL scale, and 2 different NFC groups based on Lee's[2] NFC Scale, and then asked to respond on 5 decision making scenarios. The results can be summarized as followings. First, participants preferred risk-avoidant option in gain frame, whereas risk-seeking option in loss frame. Second, there are no difference of cultural disposition on framing effects, but high NFC group showed larger framing effects than low NFC group in loss frame. Third, collectivism and vertical thinking in high NFC condition showed larger framing effects than low NFC condition.

This study investigated the tax compliance applying framing effect, with the influence of detection rates, client advocacy, risk seeking tendency on the amount of income declared. Questionaires were filled in by CFA in Busan. Questionaires involve three cases (newly founded company, loss-expected company, gain-expected company). Respondents declared least in newly founded company, next loss-expected company, to gain-expected company. Respondents declared more as detection rates rose. As client advocacy increases, newly founded company and loss-expected company declare less, while gain-expected company declare more. As risk seeking tendency increases, newly founded company and loss-expected company declare less, but gain-expected company. Finally the interaction effect between client advocacy and risk seeking tendency is supported.

In this study, we examine whether there are prospect theory investment patterns for individual investors in the real estate market. We use the maximum potential profit rate and the maximum potential loss rate of individual investors as a research method and additionally analyze it using the Jeong and Park(2015) model. As a result of the analysis, it was found that the investment pattern according to the prospect theory and disposition effect for individual investors. And we find the difference between zoning areas. This difference in investment behavior is believed to be due to the purpose of the real estate and the existence of rent fee, which creates a difference in investment behavior depending on the purpose. The limitations of this study are the analysis measurement of potential profit and potential loss using the land price index like the study of jeong and Park(2015). This implies that a new property price index needs to be developed or a benchmark for real estate assets is needed for deeper study of real estate investment sentiment.

최근 계획된 행동이론을 바탕으로 국내 증권형 크라우드펀딩 투자자의 참여의도와 무리행동에 관한 연구를 수행하였다. 연구 결과 계획된 행동이론의 주요변인 중 태도와 주관적 규범은 증권형 크라우드펀딩 투자자의 참여의도에 정(+)의 영향을 미치는 것으로 확인되었다. 그리고 간접효과 분석 결과 참여의도는 태도, 주관적 규범과 무리행동 사이에서 매개적 역할을 하는 것으로 확인되었다. 그러나 계획된 행동이론에서 행동의도의 주요 변인으로 제시된 지각된 행동통제는 참여의도에 미치는 영향이 통계적으로 비유의적인 것으로 나타났다. 대신 무리행동에는 직접적으로 정(+)의 영향을 미치는 것으로 확인되었다. 한편 국내 증권형 크라우드펀딩 투자자는 실제 투자행동을 할 때 플랫폼에서 제공되는 펀딩 진행정보를 일종의 신호로 보고 다수의 다른 투자자를 모방하여 무리행동을 한다는 것을 실증적으로 확인하였다. 본 연구는 종전 연구의 후속연구로서 국내 증권형 크라우드펀딩 투자자의 손실보전기대가 참여의도 및 무리행동에 조절적 역할을 하는지 여부를 연구해 보고자 한다. 손실보전기대는 증권형 크라우드펀딩 투자로 인해 투자자가 받게 되는 각종 혜택이나 투자조건에 따라 크라우드펀딩 투자로 인한 손실 일부 또는 전부를 보전하거나 손실 발생 가능성을 낮출 수 있다고 믿는 정도를 말한다. 본 연구를 통해 국내 증권형 크라우드펀딩 투자와 관련한 각종 혜택 및 투자조건 등이 투자자의 손실보전기대를 유발하여 투자자의 참여의도와 무리행동에 조절적 영향을 미치는지 여부를 실증적으로 확인함으로써 향후 크라우드펀딩 관계 당사자들의 동 제도 활성화 및 투자자 보호를 위한 각종 정책 및 사업계획 수립 등에 유의미한 결과로 활용될 수 있을 것이다.

Financial products entail either gains or losses, and customers' psychological reaction to these gains and losses affect the selection of the financial products. This study explains the financial customers' behavior by introducing consumers' psychological variables such as loss aversion and construal levels. According to the construal level theory, people use more abstract and higher levels of construal to represent objects that are more distant on psychological distance. Based on extant research about loss aversion and construal levels, this study proposes two hypotheses and test the hypotheses. The experimental study examines how loss aversion affects the choice between deposit products and fund products in short-term and long-term investment situations. In the long-term condition the respondents prefer fund products to deposit products, whereas in the short-term condition the respondents have showed the opposite result. Also, the effects of loss aversion on preferences for financial products have interacted with the time horizon of investments. Implications and limitations are discussed to establish more effective marketing strategies based on the results of this study.

This study examines the generalizability of the existing research in an on-line auction situation which suggests that there exist a gap between buyer's willing-to-pay price(WTP) and seller's willing-to-sell price(WTS) about the same product due to the endowment effect and consumers' loss aversion propensity. At the same time, this study also identifies and examines the potential moderating factors for the effect such as product type and consumer's goal orientation based on existing theories about consumers' gain-loss heuristics. The results show that WTS is consistently higher than WTP, and that such gap gets more pronounced when the target product is hedonic vs. utilitarian and when consumers have prevention goals vs. promotion goals. Lastly, limitations and managerial implications of this study is discussed.

This paper investigates the asymmetric effect of social sentimental on an individual stock price return. For this purpose, four companies such as POSCO, Korean Electricity, AMORE PACIFIC, KIA Motors are chosen from KOSPI listed companies in terms of dataperspective. The main estimation results are as follows: the positive opinions affect only the stock prices return of three companies while the negative opinions affect all of the companies. It shows that positive or negative texts give asymmetric effect on stock price return and the effect of negative opinions is bigger than that of positive opinions. The results imply that investors are more sensitive to the negatives since they have the tendency of loss aversion. Also, it indicates that subjective opinion on SNS can be used as the proxy for the investment sentiment.

With the development of artificial intelligence technology, interest in data-based product preference estimation and personalized recommender systems is increasing. However, if the recommendation is not suitable, there is a risk that it may reduce the purchase intention of the customer and even extend to a huge financial loss due to the characteristics of the financial product. Therefore, developing a recommender system that comprehensively reflects customer characteristics and product preferences is very important for business performance creation and response to compliance issues. In the case of financial products, product preference is clearly divided according to individual investment propensity and risk aversion, so it is necessary to provide customized recommendation service by utilizing accumulated customer data. In addition to using these customer behavioral characteristics and transaction history data, we intend to solve the cold-start problem of the recommender system, including customer demographic information, asset information, and stock holding information. Therefore, this study found that the model proposed deep learning-based collaborative filtering by deriving customer latent preferences through characteristic information such as customer investment propensity, transaction history, and financial product information based on customer transaction log records was the best. Based on the customer's financial investment mechanism, this study is meaningful in developing a service that recommends a high-priority group by establishing a recommendation model that derives expected preferences for untraded financial products through financial product transaction data.
