일반적으로 정보유출사건은 외부 해커에 의해 발생된다고 생각되지만 내부자에 의한 직간접적인 정보유출사건이 더 많고 전체 유출비중의 과반 수 이상을 차지하기 때문에 내부자 유출에 대한 대비가 필요하다. 본 연구에서는 일반 억제 이론과 합리적 선택 이론을 기반으로 교통심리학 분야에서 연구되었던 행동결정요인인 위험감수성과 상황불안을 통합해 연구모델을 구성하고 설문조사를 통해 실증분석 하였다. 분석 결과, 위험감수성이 지각된 처벌의 심각성 및 확실성에 미치는 영향은 통계적으로 유의미하지 않았으나, 지각된 이익, 상황불안, 지각된 처벌의 심각성 및 확실성은 정보유출의도에 영향을 주는 것으로 확인되었다.

Purpose The purpose of this study is to investigate the factors which affect users' fatigue and reluctant intention of using a SNS. In particular, this study focused on the fatigue of SNS users, as the recent excessive use of SNS has led to negative effects such as invasion of privacy, addition and social overload. fatigue This research will explain how producing adverse effects by using SNS caused psychological and mental depression. Previous researches explained that mental fatigue associated with SNS is not simple one and it is complicated with various psychological factors. Considering this fact, this study introduced a behavioral economics concept and a social comparison theory in the research model. Design/methodology/approach For research purposes, this study developed research hypotheses in order to empirically examine the factors that affect SNS users' fatigue and reluctant intention. The empirical research was based on a poll done through 800 research candidates in the SNS fields and the final 451 responses were collected and used in statistical data analysis. The adaptability, trust, and validity to measurement model were verified and the structural relationship in the research model was analyzed through these 451 responses. Findings First of all, maintenance fatigue of SNS had a positive significant effect on coupling and fatigue of SNS and information privacy had a non-significant effect on fatigue. Second, coupling had a negative significant effect on rational inattention, however, perceived cost had a non-significant effect on rational inattention. Third, lateral/upward comparison had a positive significant on user's negative emotions. Meanwhile, user's negative emotions did not have a significant effect on rational inattention.

우리는 여러 종류의 인과적 믿음을 지니고 있으며, 인과적 믿음은 합리적인 결정을 내리는 과정에서 중요한 역할을 한다. 이 직관을 발전시킨 인과적 결정 이론은 행위자의 결정이 합리적이라는 설명을 제시하기 위해서 그 행위자의 결정이 의존하는 인과적 믿음을 명확하게 밝히는 것이 필요하다고 주장한다. 그럴 필요가 없다는 입장의 증거적 결정 이론은 뉴컴 문제를 통해 반박된다. 그러나 뉴컴 문제의 다양한 형태 중에서 의학의 뉴컴 문제가 증거적 결정 이론을 반박하는 데에 가장 성공적이라는 일반적 판단은 잘못이라는 점이 본 논문에서 논증된다. 본 논문은 의학의 뉴컴 문제는 인과 관계를 명료하게 진술함으로써 오히려 증거적 결정 이론을 반박하기 어려워진다는 점을 지적한다. 이 과정에서 본 논문은 증거적 결정 이론과 인과적 결정 이론 사이의 차이점을 드러내고, 합리적 결정 과정에서 인과적 믿음이 정확하게 어떤 역할을 하는지를 밝힌다.

Compliance with information security policies has been an important managerial concern in organizations. Unlike traditional general deterrent theory, this study proposes whistle-blowing as an alternative approach for reducing internal information security policy violations. We build on the theories of planned behavior and rational choice as well as develop a theoretical model to understand the factors that influence whistle-blowing attitudes and intention at both the organizational and individual levels. Our empirical results reveal that altruistic and egoistic concerns are involved in the development of whistle-blowing attitudes. The results not only extend our understanding of whistle-blowing motivation but also offer directions to managers in promoting internal disclosure of information security breaches.

Purpose - For the past several decades, behavioral economics or behavioral decision theory has undergone rapid development. This study provides a critical review of the development of behavioral economics with a focus on what are deemed to be core theories in the field. Starting from the utility function proposed by Daniel Bernoulli in the 18th century, the development history of utility functions until the emergence of the prospect theory is thoroughly reviewed. Some of the experimental results violating the traditionally assumed utility function and supporting the prospect theory value function are summarized. The most representative principles of rational choice are transitivity, independence from irrelevant alternatives (IIA), and regularity. The development of behavioral economics has been triggered by finding counter-examples to these principles. Some of the choice behaviors discussed in this study as counter-examples to the traditional theories of rational choice are the St. Petersburg paradox; the Allais paradox; gambling behavior; and the various context effects including the similarity effect, attraction effect, and the compromise effect. The Elimination-by-Aspects (EBA) model, which was proposed as an explanation for the similarity effect, is discussed in detail as well. Based on the literature review and further analysis, this study summarizes the relationship between the context effects, prospect theory, and EBA model. Research design, data, and methodology - This study provides an extensive literature review on several important theories in the field of behavioral decision theory and adds some critical comments to the theories and the relationships among them. This study first reviews the development of utility functions. Daniel Bernoulli introduced the concept of utility function to solve the St. Petersburg paradox. In the mid-20th century, Herbert Simon proposed the "satisficing" heuristic and presented a value function with a shape different from traditional utility functions. This study highlights the strengths and weaknesses of several utility functions proposed until the emergence of the prospect theory value function. Results - This study posits that prospect theory and EBA model are the two most important theories in the field of behavioral decision theory. They can explain various choice behaviors that traditional utility maximization analysis has been unable to. The application of these models to various fields is further increasing nowadays. This study explains how prospect theory and the EBA model can be used to explain the context effects. Conclusions - The traditional economic theory relies on a single variable called "utility" in explaining consumer choice. However, this study argues that, in investigating consumer choice, several other variables should also be considered. These are the similarity among alternatives, an alternative's prototypicality within the category, the dominance relationship between alternatives, and the reference point in evaluating alternatives. Due to the development of behavioral economics, we are now closer to a more complete understanding of consumer choice behavior than in the past when we had only a single tool called utility.

We are evidently Home Economicus, egoistic rational utility maximiger, and all the capitalism economic situation make us adapt to such life, and recognize that it is rational to act like that. This can be demonstrated in Prisoner′s Dilemma(PD) which always select the non-cooperative choice for free rider in rational selection process of public goods. This paper notice the "what is problem\ulcorner"The problem is not in free rider itself but in free rider egoism. The practical behavior of free rider egoism can be explained by way of Prisoner′s Dilemma. In PD situation, the prisoner makes a rational choice, non-cooperative alternative, but he doesn′arrive at preto-optimality. It is dilemma. Why can′t he arrive \ulcorner Because he is isolated from other prisoner. So we call it prisoner′s dilemma. The PD situation can be compared with our real economic life, which, we think, have kept by rational choice of the public goods. We actually have made our life as an individual one although we organized communities of capitalism. Of course, we know each others as members of same society, but each individual being can′t secure the belief, which has composed basis of community. So, it is very similar and common between PD situation and our real economic life in the production of public goods. We conclude that this non-cooperative process of PD situation can be utilized as instrument of EE. So this non-cooperative process can show us the effectiveness of EE as follows. \circled1 Game situation life PD can be used as good instrument for explaining the rational selection dilemma(error) to Homo-Economicus, the rational agent, with the optimal and rational language. \circled2 We can show that the selection result is dilemma, not arrive pareto - optimality. \circled3 The dilemma can be resolved with accomplishing the good communal life based on the belief, not on the isolation.

Rational choice theory holds that the alternative with largest expected utility in the choice set should always be chosen. However, it is often observed that an alternative with the largest expected utility is not always chosen while the choice task itself being avoided. Such a choice phenomenon cannot be explained by the traditional expected utility maximization principle. The current study posits shows that such a phenomenon can be attributed to the gap between the expected perceived gain (or loss) and the expected perceived value. This study mathematically analyses the relationship between the expectation of an alternative's gains or losses over the reference point and its expected value, when the perceived gains or losses follow continuous probability distributions. The proposed expected value (EV) function can explain the effects of loss aversion and uncertainty on the evaluation of an alternative based on the prospect theory value function. The proposed function reveals why the expected gain of an alternative should exceed some positive threshold in order for the alternative to be chosen. The model also explains why none of the two equally or similarly attractive options is chosen when they are presented together, but either of them is chosen when presented alone. The EV function and EG-EV curve can extract and visualize the core tenets of the prospect theory more clearly than the value function itself.

The so called Antarctic Treaty System, started from the Antarctic Treaty in 1959, has gradually been enlarged into the concept of an international environmental regime, which has been included in not a few international institutions, treaties, conventions, and international non-governmental organizations (INGO). This kind of movement, as in the role of an international environmental regime, has recently been highlighted in the Protocol on Environmental Protection to the Antarctic Treaty. This Protocol is taking appropriate measures as an international environmental regime in regulating its member nations by enforcing principles in protecting Antarctic resources and environment, regulating member nations' Antarctic activities, establishing norms in the adoption of international and domestic laws, and devising regulations for deciding administrative actions through the member nations' collective decision-making procedures. h this context, this paper is to test a few questions; firstly, how the Antarctic Treaty System can be related with the role of international environmental regime; secondly, how the theories of international environmental regime, such as the hegemony theory, rational choice theory, and international morality theory, can be tested in the role of Antarctic Treaty System as an international environmental regime. Finally, this paper provides a solution for the future problems of the Antarctic Treaty System as an international environmental regime regarding the regime's principle (conflict between the environmental principle and the right of nation-state), norms and regulations (the conflict between the developed and underdeveloped nations in terms of the concept of 'common but differentiated environmental responsibility'), cooperation directions (the leadership problems between hegemonic nation and multilateral leading groups), and management methods (cooperation and arrangement problems among expert institutions, observer groups, and INGO).

경제제재와 경제지원은 외교적 목표를 달성하기 위한 중요한 수단의 하나로 인식되어 왔다. 그러나 경제제재와 경제지원의 효과에 대한 이론적 연구는 크게 미흡하다. 기존의 연구들은 거의 대부분 사례 분석에 초점을 맞추고 있기 때문이다. 이론적 분석을 시도한 연구들도 존재하나, 경제제재나 경제지원의 발의국과 대상국이 합리적이라는 전제하에 비용과 효용의 계산에 영향을 미치는 변수들에 초점을 맞추어 논의를 전개한다. 그러나 실제 현실에서는 대상국의 행위를 합리적 결정이라고 설명할 수 없는 경우가 자주 발견된다. 이러한 현상에 대해 기존 연구들은 합리적 행위자라는 전제는 그대로 둔 채 추가 변수의 도입 등을 통해 설명력을 높이고자 해왔다 그렇기 때문에 현재까지 경제제재에 관한 연구는 변수 확장의 형태로만 진행되어 사회과학의 간결성을 훼손시키는 방향으로 나아가고 있다는 지적에서 벗어날 수 없게 된 것이다. 이러한 연구 흐름의 문제점을 극복하기 위한 방안의 하나로서 본 연구는 전망이론(prospect theory)을 이용하여 경제제재와 경제지원의 효과를 이론적으로 논의한다. 전망이론은 현실 세계에서 실제로 나타나는 의사결정을 설명하고자 하는 이론이며, 합리적 선택에 의한 최적 결정(optimal choice)을 도출하고자 하는 이론으로서 변수의 확장이 아닌 변수에 대한 새로운 이해의 틀을 제공한다. 그러므로 전망이론의 도입은 개별 사례마다 새로운 변수들의 추가 없이 사례에 대한 일반적인 설명력을 높일 수 있을 것으로 기대된다. 연구 결과, 제재 혹은 지원 대상국의 준거점이 높아지면 경제제재의 효과는 감소하고 경제지원의 효과는 증가한다. 본 연구는 경제제재와 경제지원의 효과 분석에 전망이론을 활용한 최초의 연구라는 점에서 학술적으로 의의를 지닌다. 뿐만 아니라 본 연구의 분석 결과는 향후 대북정책에 대해서 의미 있는 시사점을 제공할 수 있을 것으로 기대된다.

The recent global economic crisis has resulted in increased discussion and attention on the sharing economy, a form of economic activity where individuals share currently available products. This study investigates consumer sharing economy usage attitudes and usage intentions by applying rational choice theory. For this study, an investigation that had 400 adult consumers from across Korea answer a structured questionnaire was conducted. A statistical approach using SPSS ver. 22.0 was used to analyze the data. The study found that the consumer's sharing economy value and participation levels were higher than usual. Higher than usual consumption patterns were seen for the construct of rational behavior theory. An analysis of the relative influence of variables regarding sharing economy usage intention also found that usage intention was higher for those who had experienced using a sharing economy services rather than those who did not have experience. In addition, the sharing economy usage intention also increased along with the values for subjective norms, sharing economy usage attitudes, sharing economy participation, sharing economy emotional benefits, and increased values. This study found that fundamental materials for consumer education should be made to eliminate difficulties that consumers have when they use sharing economy services. It is also expected that economic policy will develop to stimulate the sharing economy in a stable manner, that sharing economy-related information will be provided to consumers, and that consumer policies will be prepared to prevent consumer problems before they occur.
