URBAN CLUSTERS AS GROWTH FOCI*

ABSTRACT Urban clusters are geographic concentrations of urban places, some of which may include major cities. Unlike agglomerations, whose geographic boundaries are clearly delineated, urban clusters have “variable” boundaries, with each urban settlement being part of its “own” cluster of populated places, located within its commuting range. As our study indicates, the effect of clustering on urban growth is not uniform: it appears to be positive in low density clusters, and negative in densely populated ones. In particular, outside densely populated areas, towns surrounded by other localities tend to evince higher rates of population growth than their “lone” counterparts.     

The 1948 war veterans and postwar reconstruction in Israel

This article deals with the characteristics of postwar reconstruction in the State of Israel at the end of the 1948 war and during the early 1950s, focusing on the patterns and priorities of reconstruction of society as a whole and the rehabilitation of veteran soldiers in particular. The article addresses the social impact of the rehabilitation of the 1948 war veterans on the emerging Israeli society, including the creation of a social distinction between different sectors undergoing rehabilitation in terms of employment and housing. The article also discusses the social and political protests that accompanied the rehabilitation of the demobilized soldiers who campaigned for recognition and commemoration.     

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.
