ANALYSIS OF A DYNAMIC RESIDENTIAL LOCATION CHOICE MODEL WITH TRANSACTION COSTS*

ABSTRACT. This paper incorporates transaction costs in a residential location choice model. An individual's choice is assumed to be an outcome of a two-stage process: a decision to change, or to undertake a transaction and, conditional on a change occurring, a choice of a new alternative. The dynamic choice model is aggregated to yield a Markovian model of residential location patterns. It is shown that recent contributions to dynamical urban modeling correspond to special cases of the deterministic version of this model. The Markovian model is used in a theoretical analysis of the influence of transaction costs on the properties of the stationary state. The effects of residential mobility rates and of interdependencies among individuals, caused by supply-side and density-related interactions, are also analyzed. It is shown how these dynamical factors modify the stationary state, thereby demonstrating the type of errors which may occur with static models that omit them.     

Changing Jobs and Changing Houses: Mobility Outcomes of Employment Transitions

The life-course approach to residential mobility and migration recognizes a central role for a variety of demographic and economic triggers in the mobility process. Having a child, getting married, separated, or divorced, have all been identified as triggers that generate residential relocations. It is obvious that a job change can also be viewed as a stimulus for residential relocation, although until now the interconnection has been evaluated mainly for long-distance migratory moves rather than for its effects on residential mobility. In this analysis we use the Panel Study of Income Dynamics to test the association between employment changes and residential relocation. We examine both the occurrence and the timing of residential moves triggered by employment transitions. We show that job changes increase the likelihood of residential relocation in the aggregate and for singles when we hold other & "triggers" constant. The results of the analysis of the timing of job changes and residential relocations indicate that temporal differences exist between households types. Overall, the results establish that job change is an important triggering process in residential relocation and emphasizes the interconnected nature of life-course events.     

NEIGHBORHOOD DYNAMICS AND PRICE EFFECTS OF SUPERFUND SITE CLEAN‐UP*

ABSTRACT Numerous hedonic price analyses estimate price effects associated with hazardous waste site remediation or other environmental variation. This paper estimates a neighborhood transition model to capture the direct price effect from Superfund site clean‐up and the indirect price effects arising from residential sorting and changes in investment in the housing stock following clean‐up. First‐difference models of neighborhood change and a national sample are used. This approach fails to find consistent positive direct price effects. Positive indirect effects, however, may arise through residential sorting and neighborhood investment spurred by remediation. The findings can be sensitive to policy endogeneity and model specification.

TIPPING AND RESIDENTIAL SEGREGATION: A UNIFIED SCHELLING MODEL*

ABSTRACT This paper presents a Schelling‐type checkerboard model of residential segregation formulated as a spatial game. It shows that although every agent prefers to live in a mixed‐race neighborhood, complete segregation is observed almost all of the time. A concept of tipping is rigorously defined, which is crucial for understanding the dynamics of segregation. Complete segregation emerges and persists in the checkerboard model precisely because tipping is less likely to occur to such residential patterns. Agent‐based simulations are used to illustrate how an integrated residential area is tipped into complete segregation and why this process is irreversible. This model incorporates insights from Schelling's two classical models of segregation (the checkerboard model and the neighborhood tipping model) and puts them on a rigorous footing. It helps us better understand the persistence of residential segregation in urban America.

Minority–Majority Relations in the Schelling Model of Residential Dynamics. 住宅动态迁移Schelling模型中的少数‐多数关系

The Schelling model describing segregation between two groups of residential agents, reflects the most abstract, basic view of noneconomic forces motivating residential migrations: be close to people of “your own” kind. The model assumes that residential agents, located in neighborhoods where the fraction of “friends” is less than a predefined threshold value F, try to relocate to neighborhoods where this fraction is F or higher. For groups of equal size, Schelling's residential pattern converges either to complete integration (random pattern) or segregation, depending on F. We investigate Schelling model pattern dynamics as a function of F in addition to two other parameters—the ratio of groups' numbers, and neighborhood size. We demonstrate that the traditional integration–segregation pattern dichotomy should be extended. In the case of groups of different sizes, a wide interval of F‐values exists that entails a third persistent residential pattern, one in which a portion of the majority population segregates while the rest remains integrated with the minority. We also demonstrate that Schelling model dynamics essentially depend on the formalization of urban agents' residential behavior. To obtain realistic results, the agents should be satisficers, and the fraction of the agents relocating irrespective of the neighborhood's state should be nonzero. We discuss the relationship between our results and real‐world residential dynamics.     

RESIDENTIAL MOBILITY AND NEIGHBORHOOD QUALITY*

ABSTRACT. This paper presents evidence on the factors causing residential mobility within inner-city neighborhoods. A theoretical model is presented which posits that intraurban mobility is a response to housing consumption disequilibrium. Our data and methodology permitted more accurate measurement of disequilibrium than in previous studies, including the disequilibrium arising from neighborhood change. The major conclusion we draw from our results is that households' perceptions of the level of neighborhood quality and its change influence the mobility decisions of both renters and homeowners residing within central cities. Also, in comparison to other measured factors, neighborhood variables were found to be strong mobility predictors regardless of housing tenure. Our results imply that neighborhood improvement policies may succeed in stabilizing inner-city neighborhoods.     

Functional change as an indicator of transformation near the old city centre of Istanbul

Over time, the residential areas close to city centres have experienced change in their function and social structure. In Istanbul a functional and social change is also observed, especially in the residential buildings near the historical city centre. This study investigated this process of transformation through a research project conducted in the southern part of the Istanbul Historical Peninsula (old city centre) and documents the recent functional changes in this district. It also considers the role of tourism in the process of inner city transformation. On the basis of the data collected during the study, proposals are forwarded for the future development of the area.

Residence and Workplace Relocation: A Bivariate Duration Model Approach

Different economic theories suggest that residential and labor market relocations are mutually related. This has been verified in various empirical studies. We analyze this relationship based on a bivariate duration model of residential and labor market mobility. This specification is motivated by a search model that allows for simultaneous search on the labor and housing market, taking commuting costs into account. We investigate this relationship by using information on job and residence durations. In order to be able to analyze properly empirical duration data, we derive the statistical distributions of interest. Our empirical results based on a Dutch sample of full-time employed workers show that residential and labor market mobility depend positively on one another, which is in line with the theoretical search model presented. Moreover, we present easy-to-interpret measures for this dependency.

Trends in the residential mobility of seniors in Canada, 1961–2006

This article examines residential mobility for seniors 65 years of age and older in Canada using census data from 1961–2006. We addressed three questions. First, have seniors been increasingly likely to change their residential location within Canada or alternatively become increasingly likely to age‐in‐place? Second, has the in‐migration of seniors to Canada from other countries become more pronounced over the years? Third, does the residential mobility of seniors vary by age and sex? We used census data to calculate the percentages of seniors who changed their residence in the five‐year periods prior to each of the 1961–2006 censuses and the percentages of seniors who moved in the previous year for the 1991–2006 censuses. We calculated the percentages of seniors making local moves, longer distance moves within the same province, moves from one province to another, and moves to Canada from another country. We found that rates of residential mobility for seniors tended to increase in the 1961–1981 period but have been lower and relatively consistent from 1986–2006. We found no evidence to suggest a pattern of sustained increase in residential mobility of seniors. We conclude that Canadian seniors tend to age‐in‐place and that when seniors do change residence, the likelihood of residential mobility decreases with the distance of the move and decreases with age. Nevertheless, the likelihood of changing residence may increase for seniors 75+ years of age who need assistance and are at risk of institutionalization. We found that senior women were more likely to change residence locally than senior men. Finally, we found that from 1961 to 2006 between 0.8 percent and 1.4 percent of seniors had migrated to Canada in the five years prior to each census from other countries and that this pattern has fluctuated over the past half century with no clear trend.     

A Decision-Making and Search Model For Intraurban Migration

Most of the research on the intraurban migration attempting to develop models of the mobility process has presented intuitively appealing statements about the residential decision process, but stopped short of a formal development of these concepts. If it is to be possible to predict the mobility pattern within the city, both the search and selection process must be more clearly specified. In this paper, a preliminary theoretical model containing decision rules similar to those found in optimal search models is developed. The model explicitly incorporates the spatial and temporal aspects of residential choice and has the potential to predict the probability that a prospective migrant will search for a new residence in a given area of the city, the time when the search process will come to a conclusion and, by implication, the expected location of the new residence. The preliminary results from the model suggest a major elaboration of the spatial and temporal aspects of residential choice under conditions of uncertainty in terms of a set of empirically measurable determinants, relating to a household's preferences, beliefs, and degree of risk aversion.

THE EFFECTS OF LOCAL TAXES AND PUBLIC SERVICES ON RESIDENTIAL DEVELOPMENT PATTERNS*

ABSTRACT. This paper incorporates an exogenous taxing and service-providing public sector into a dynamic residential land-use model in order to examine how local-government fiscal policies alter the pace and pattern of residential development. The model is used to derive the comparative-dynamic responses to variations in the income, sales, and property taxes and public-service time paths. The results show how tax and expenditure effects systematically depend upon the anticipated relative growth rates in rents to alternative uses and vary across locations within a given urban area as well as across urban areas themselves.
