경제학의 일반균형이론은 만족할 만큼 정립되어 있지 못하다. 그러나 존재문제에 관하 이론은 안정성문제에 관한 이론보다 비교적 잘 정리되어 있다. 본고에서는 일반균형의 존재이론을 중심으로 하여 대규모 사회-경제 시스템에 대한 연구현황을 개관하였다.

This study was conducted for the purpose of comparing the advertising effect of Korean companies and Vietnamese domestic companies by applying the balance theory to Vietnamese consumers emerging as a new market for Korean companies. An experiment was conducted on female university students, and cognitive, emotional, and behavioral responses to advertisements in the two countries were investigated. The results showed that there was no difference in the cognitive dimension of Vietnamese consumers' evaluation of advertisements in Korea and Vietnam, but there is a difference in the emotional dimension and the behavioral dimension. This study contributed theoretically to the possibility of applying the balance theory to the study of international advertising effects, and the implications of international advertising of Korean companies in the underdeveloped markets were discussed.

This study aimed to examine the mechanisms underlying digital game usage behavior by applying the Theory of Planned Behavior and the Balance Theory. It investigated the influences of attitude, subjective norms, and perceived behavioral control on the intention to use digital games, as well as the differences in the application of the Theory of Planned Behavior model based on the balance state among individuals, significant others, and digital games. A total of 315 responses from adult PC game users were collected through an online survey conducted from October 21 to 25, 2021, and were analyzed using multiple regression analysis. The results revealed that attitude and perceived behavioral control had a significant positive impact on the intention to continue using digital games, while subjective norms did not exert a significant influence. By categorizing groups into balanced, unbalanced, and imbalance states based on the balance relationship, the application of the Theory of Planned Behavior model showed that in the unbalanced and imbalance groups, both perceived behavioral control and attitude had a positive impact on the intention to continue using digital games. However, in the balanced group, attitude only had a positive impact on the intention to continue game usage. This study contributes to understanding digital game users by examining both individual psychological factors and the influence of others on digital game usage behavior.

Thomson(1977) proposed that the equilibrium status can exist among modes when each mode's attractivenesses' are equal. His theories key point is that when the equilibrium status is achieved the additional investment for individual car user such as constructing more roads or widening the existing roads, can lead to more congestion. That's the so called 'Downs-Thomson's Paradox. This paper is intended to demonstrate that the paradox is applicable to Seoul Metropolitan area. Before doing that job, we reviewed Downs-Thomson's paradoxes related Papers such as Mogridge's (1985) research for London case. and Seung Jea-Lee's(2004) research for Seoul. In conclusion, the equilibrium status that Thomson proposed can't be applied to Seoul Metropolitan area. because the suppressed demand's behaviour is different from real situation and that of in the theory.

This study examines the distribution of power in Northeast Asia based on the balance of power theory, a representative theory of realism, assuming military capabilities as the core power of states. The results of previous studies on the balance of power and military forces are reviewed and used to analyze changes in the strength of the US, China, Russia, Japan, South Korea, and North Korea through 2020 to predict the security environment in 2030. In the balance of power theory, if the balance of power between a nation or a group of powers collapses, the possibility of war is high, and to survive in the international community with high uncertainty and distrust, the theory predicts that states must increase their powers in a self-help world and strengthen cooperation and alliance. Countries in Northeast Asia are also continuing to strengthen their military capabilities, and countries neighboring China are paying keen attention and remaining vigilant due to the rapid changes in the international security environment after the rapid rise of China. To mark the future 100th anniversary of the Chinese armed forces in the 2030s, China aims to realize 'defense and military modernization' and build a 'world-class military force' by the nation's 100th anniversary in the 2050s. The US is busy checking China's rise by strengthening international cooperation and alliances. The security environment and power dynamics in Northeast Asia are slowly changing as the US and China continue to compete for global hegemony. The changes and implications of the distribution of power in Northeast Asia after 2030 are examined based on the balance of power theory.

Previous research regarding budget analysis has been mostly limited to describing annual changes in defense budgets relative to total budgets without a theoretical background. More empirical defense budget research is needed with better data. This study conducts an empirical analysis of national defense expenditures using Punctuated Equilibrium Theory (PET). The purpose of this study is to examine trends in the Republic of Korea's (ROK) functional defense budgets (total defense budget, force operation budget, force improvement budget) and to identify and analyze radical points of change in the defense budget using punctuated equilibrium theory. This study also explores trends and punctuations in the national defense budgets using annual defense budget data from the ROK for every year from 1998 to 2017. This study finds that from 1998 to 2017 the spending pattern of the total defense budget in the ROK was characterized by 19 years of stable growth and a one-time punctuation (5.0%). The force operation budget exhibited stable growth in eighteen years and was punctuated twice (10%). The force improvement budget was punctuated five times.

This study analyzes the dispute settlement of between arbitration and litigation using a game theoretical approach. Many studies on arbitration have so far focused on the relevant institutions. However, there are few theoretical studies that have focused on the demand side of arbitration. The model presented here suggests conditions under which arbitration form a perfect Bayesian Nash equilibrium, provided that the players strategically choose a dispute settlement tool. Furthermore, the suggested model is used to analyze simple cases of international commercial dispute cases.

본 연구에서는 일반균형이론을 이용하여 버스전용차로의 효과분석모형을 정립하였 고, 이 모형을 이용하여 경부고속도로의 버스 전용차로에 대한 효과분석을 수행하였다. 본 연구에서 제안된 버스전용차로 효과분석모형에 있어 수요모형으로는 로짓 모형을 사용하였 고, 서비스모형, 즉 공급모형으로는 지체함 수식을 사용하였다. 이를 통하여 버스전용차로 설치에 따른 교통수단간 전환수요를 내생화 하였다. 경부고속도로를 대상으로 한 사례분석 의 결과, 버스전용차로의 효과를 극대화하는 혼잡수준이 존재한다는 것과, 버스전용차를 설 치할 경우 교통수단간의 수요전이효과에 따라 버스뿐만 아니라 일반 차로를 이용하는 승용 차의 통행여건도 개선된다는 사실을 발견하였다.
