본 연구에서는 여행자 휴대품 통관 과정을 게임으로 바꾸어 표현한 후 불완전정보게임의 균형 개념으로 널리 활용되는 (완전)베이즈균형 개념을 바탕으로 여행자 및 세관의 균형전략을 도출한 후 게임의 균형 하에서 여행자의 자진신고 비율에 영향을 미치는 요인을 정리하였다. 게임의 균형에 의하면, 여행자의 자진신고 비율은 면세범위초과 물품에 대하여 지불해야 하는 비용의 크기와 면세범위초과 물품을 운반하는 여행자 비율에 대한 사전적인 믿음의 정도에 비례하고 휴대품 검사에 따른 세관의 비용의 크기에 반비례하는 성격을 갖는다는 것을 알 수 있다. 이러한 게임의 균형이 갖는 성질을 바탕으로 여행자 통관에 있어서 자진신고 비율을 증가시킬 수 있는 정책적 대안을 제시하였다.

In this study, I have tried to investigate the factors that affect the ratio of voluntary declaration in passenger's clearance under the equilibrium of passenger's clearance game. To achieve this purpose, I changed the passenger's baggage clearance process into the imperfect information game model and applied the concept of (perfect) Bayesian equilibrium. According to the equilibrium of game, the ratio of voluntary declaration is directly proportional to cost(tariff, fine, etc) of carrying goods in excess of duty free allowance and prior common belief on the ratio of passengers having goods in excess of duty free allowance, and inversely proportional to passenger's baggage inspection cost of customs. Based on the equilibrium of game, I have suggested several policy plans to increase the ratio of voluntary declaration in passenger's clearance
