거주지 결정, 통근 vs 이사 비용-효용 모델 제시
이 논문은 주거지 결정 시 발생하는 commute과 move 사이의 선택을 분석하기 위해 cost-and-place-utility를 통합한 대수적 모델을 제안합니다. 기존의 housing expenses와 commuting costs 중심의 이론을 넘어, income-related affordability limits와 indirect social/service access costs를 단일 utility-maximization framework 내에 포함했습니다. 이 모델은 30% housing affordability rule을 제약 조건으로 활용하여, 직접적인 재정적 비용과 가중된 사회적 이익을 통합한 decision rule을 도출합니다.
arXiv:2606.31780v1 Announce Type: new Abstract: Deciding where to live involves a complex balance between commuting and moving, as households must weigh housing affordability, transportation expenses, access to workplaces, and social ties. Traditional urban economic theories focus on the balance between housing expenses and commuting costs, while modern studies also consider housing affordability, transportation access, and utility maximization. However, few studies have combined these elements into a clear mathematical model that can be used for both policy analysis and household decision-making. This paper introduces an algebraic model for deciding whether to commute or move, expanding on traditional residential location theories by including direct housing and commuting expenses, income-related affordability limits, indirect social and service access costs, and location-based utility within a single utility-maximization framework. The model uses the common 30% housing affordability rule as a constraint, acknowledging that residential choices are also shaped by social networks, access to institutions, neighborhood ties, and quality-of-life factors. The decision rule derived from the model integrates direct financial costs with weighted social benefits and indirect access costs to assess when moving offers more overall utility than staying put and commuting. Unlike complex discrete-choice, nested-logit, or agent-based models, this framework offers a mathematically clear, understandable, and flexible decision model that can easily be expanded to include more household characteristics, transportation options, or policy factors. The model advances urban economics, migration studies, and housing affordability research by providing a practical analytical tool for assessing residential mobility decisions within financial and behavioral limits.
