In this paper we develop a dynamic model that explains the pattern of population and production allocation in an economy with an urban location and a rural one. Agglomeration economies make urban dwellers benefit from a larger population living in the city and urban firms become more productive...

Germany like many other European countries subsidize commuting by granting the right to deduct commuting expenses from the income tax base. This regulation has often been changed and has regularly been under debate during the last decades. The pros (e.g. causing efficiency gains with respect to...

The role of population density for economic activity was neglected in most part of economic theory. This paper is a review and extension of the previous works of the author in this field. So far, densities did not become common economic variables in economic analysis, and two countries with...

We develop a model of a city populated by heterogeneous agents. Agents self-select into entrepreneurship, and entrepreneurs set up firms which hire workers. We characterize the equilibrium matching between firms and workers, as well as the within-city assignment of agents to locations. We then...

City size distributions are known to be well approximated by power laws across many countries. One popular explanation for such power-law regularities is in terms of random growth processes, where power laws arise asymptotically from the assumption of iid growth rates among all cities within a...

Since decade 80`s, colonies of illegal settlements began rapidly increasing in many urban areas of cities in Indonesia. During the decade, urban population living in slum areas was recorded about 54% of total urban population particularly in mega cities of Indonesia. Nonetheless, that percentage...

The aim of the study is to compare the methodology of spatial model building of two very influential economists, Thünen and Krugman. Thünen is a representative nineteen century economist and Krugman represents the method of contemporary neoclassical mainstream economics. Thünen is mostly...

We develop a model where workers both choose their residential location (geographical space) and social interactions (social space). In equilibrium, we show under which condition the majority group resides close to the job center while the minority group lives far away from it. Even though the...

Reproducing the socio-spatial structure of cities is one of the challenges facing the standard urban economics model of Alonso, Muth, Mills (AMM model). In a widely cited paper, Jan K. Brueckner, Jacques-François Thisse and Yves Zenou (1999) asked "Why is central Paris rich and downtown Detroit...
