  • Purpose - The purpose of this paper is to compare and review behavioral economics models that explain stock price changes after large-scale price shocks in the Korean stock market and to find a suitable model. In this paper, among the theories reviewed, it was confirmed that the anchoring heuristics theory has high explanatory power for stock prices after large-scale stock price fluctuations. Design/methodology/approach - This paper conducts an event study on stock price shocks in which the individual stocks that make up the KOSPI200 index show more than 10% fluctuation on a daily basis. In order to materialize the abstract predictions of heuristics theories in a varifiable form, this paper uses the daily stock price index change as a reference point for availability heuristics, and uses the 52-week highest and lowest price as reference point for anchoring heuristics. Research implications or Originality - As a result of the empirical analysis, the stock price reversals did not consistently appear for changes in the daily index. On the other hand, the stock price drifts consistently appeared around the 52-week highest and the 52-week lowest price. And in the multiple regression analysis that controlled for company-specific and event-specific variables, the results that supported the anchoring heuristics were more evident. These results suggest that it is possible to establish an investment strategy using large-scale price change in Korean stock market.

  • 2008년 글로벌 금융위기 이후 국내의 주택시장은 침체기를 겪고 있으며 이에 따라 주택가격의 하락, 임대주택가격의 상승등과 같은 주택시장의 문제점이 발생하였다. 주택시장의 정상화를 위해 정부에서는 다양한 주택정책을 발표하였으나 주택시장은 아직 회복세를 보이지 않고 있다. 따라서 본 연구는 주택시장의 침체 원인 분석하기 위해 주택 시장의 주요 참여자인 주택공급자와 주택 수요자를 기존의 수요 공급 원리에 의해서 분석하며 이들의 거래의사에 영향을 미치는 심리적 요인을 행동경제학 이론을 바탕으로 분석한다. 이의 분석 결과를 바탕으로 시스템다이내믹스 시뮬레이션 방법론을 사용하여 발표된 정책의 실효성을 검증한 결과 정책의 입안 기간에 따라 주택 거래량과 주택담보대출 총액이 영향을 받는 것으로 나타났다.

  • 모바일 화폐는 금융 서비스 제공에 혁명을 일으켜 신흥국, 특히 동 아프리카 국가의 금융에 대한 접근성을 향상시킬 수 있는 금융 포용을 가능하게 하는 핵심 요소이다. 따라서 본 연구는 UTAUT2 모델을 이용하여 에티오피아에서 모바일 화폐 서비스를 채택하려는 개인의 행동 의도 및 실제 사용에 영향을 미치는 주요 결정 요인을 분석하는 것을 목표로 한다. 본 연구 모델과 가설은 에티오피아의 여러 지역에서 200명의 응답자를 추출하여 테스트했다. 데이터 분석 결과는 정부 지원, 성과 기대, 촉진 조건, 모바일 화폐 서비스에 대한 신뢰 및 노력 기대가 에티오피아의 모바일 화폐 서비스 사용에 영향을 미치는 주요 요인으로 도출된 반면, 사회적 영향과 낮은 거래 비용 요소는 통계적으로 유의하지 않은 것으로 나타났다. 본 연구 결과는 모바일 화폐 서비스의 낮은 수수료 책정보다는 적절한 정책과 규정을 통한 모바일 화폐 서비스 활성화를 위한 에티오피아 정부의 적극적 노력과 지원만이 자국의 모바일 화폐 서비스 채택 및 보급을 촉진할 수 있다는 유용한 정보를 제공한다.

  • In this paper I examined trades of general bank In KTB212 Futures for patterns which are best described by the behavioral finance literature. I reported the statistics for traders of profit or loss traders, number of traders, total trader gross trading income, revenue per contract. Thess results are acquired from the revenue scale and the trade contract scale. When traders are ranked on the basis of performance, successful winning traders are short positions in the KTB212. This result appears more faithful to large scale traders. The evidence suggests that large traders are able to act on the information flow. The measure of success is as total income, and the relationship between position holding and success is clear.

  • The paper examines the antecedents of acceptance of social networking sites in retail franchise and restaurant businesses. The success of retail franchise and restaurant business operators via social networking sites depends not only on organizational benefits but also on their behavioral intentions of using it. Three hundred and twenty four samples collected from South Korean retail franchise and restaurant employees are analyzed using factor analysis, structural equation model techniques and one-way analysis of variance. The results of the study identify the three constructs of organizational benefits, perceived tangible assets and perceived intangible assets as for important antecedents to accept social networking sites for their business use. Moreover, higher position employees tend to have more favorable perception of tangible assets and acceptance of social networking sites for their business use.

  • The paper explores determinants of corporate adoption of social media and the role of technology acceptance model in the path. This paper assimilates some components of the technology acceptance dimension and social expectation theories to determine corporate intentions to use social media. Six hundred and forty-eight samples collected from hotel staff in Korea are analyzed using factor analysis, structural equation model techniques and one-way analysis of variance. The results show that corporate needs, social expectations, ease of use and usefulness should be viewed as important antecedents explaining the firm's behavioral intention to use social media. The study also finds that the ease of use and usefulness of the technology acceptance model have positive directional mediation effects in the path diagram.

  • The paper examines critical factors affecting consumer behavioral intentions in accepting online health communication through social networking sites. Unlike recent research under this topic, the paper assimilates some components of service quality dimensions and consumer behavior theories. The paper employs factor analysis and structural equation modelling analysis with latent variables to identify critical factors from the survey data collected from Korean consumers. The results of the study identifies three major constructs: consumer needs for health information, the perceived value of tangible attributes of health information providers, and the perceived value of intangible attributes of health information providers. The results show that consumer needs for health information and the tangible and intangible attributes of health information providers should be considered as important antecedents of accepting online health communication through social networking sites. The findings suggest that the success of online health communication via social networking sites largely depends on the tangible and intangible attributes of health information providers.

  • This study investigates whether foreign investors' behavior is involved in firm-specific investor sentiment. Because the mixed role of foreign investors on investor sentiment formation seems to exist in the Korean stock market, it needs to examine the moderate or incremental effect of foreign investors on the stock price crash risk which is due to investor sentiment. The analysis results using Korea Stock Exchanges - listed firms for the period of 2011-2019 show the increased future stock price crash risk which is attributable to high investor sentiment is mitigated for firms with the high foreign ownership, indicating the moderate effect. This study expands the literature on the foreign investors' behavior in the Korean stock market, by showing foreign investors are not involved in firm-specific investor sentiment, which improves market's efficiency in the Korean stock market. Also, the paper is valuable to the academic and practice field in that the findings shed light on the foreign investors' mitigating role in stock price crashes in the behavioral finance perspective.

  • 통일은 북한이 유지했던 계획경제 체계를 포기하고 시장경제 체제로 바꾸는 것으로 수십 년 동안 계획경제 체제 하에서 살았던 북한 주민들에게는 큰 혼란과 어려움을 야기할 것이다. 이를 위해 최근 공감대를 얻고 있는 행태경제학(Behavioral Economics)의 관점을 반영할 필요가 있다. 구체적으로 선정한 교육내용은 ① 금융 전반(금융내역기록하기, 인플레이션의 영향, 현대 금융투자시장에서 상품 선택의 물리적 어려움, 금융투자자의 제한적 합리성 등) ② 대출(개인 신용 관리, 금융권별 대출금리 차이 등) ③ 금융투자(비용이 수익률에 미치는 영향, 복리와 단리의 차이, 기대수익과 위험의 상관관계, 투자위험 유형, 분산투자의 중요성, 적극적 투자와 소극적 투자 등)이다. 다만, 각 내용의 깊이와 넓이는 북한 주민들이 직관적으로 이해할 수 있는 최소한도로 한다. 이러한 직관적이고 기본적인 금융교육을 통해 필수적인 금융지식을 갖춘 다음 구체적인 금융의사결정은 독립투자자문업자(Independent Financial Adviser, IFA)와 상의(자문)받도록 하는 것이 바람직하다. 즉, 최소한의 경제·금융지식을 갖추는데 필요한 직관적인 내용으로 국한하고 의사결정은 IFA를 활용하는 것이 합리적임을 교육하는 것이다. 이러한 '직관적 기본 금융 교육 + 독립투자자문업자(IFA)' 결합 모형은 통일후 북한 주민을 대상으로 하는 경제금융교육에 소요되는 시간과 노력을 크게 줄이면서 효과를 극대화할 수 있을 것이다.
