regional agreements can facilitate the integration of world economies by opening the borders to the trade development while accelerating technological changes and maintaining the economic growth. trade potential is defined as the trade that could be achieved at an optimum trade frontier with the open and frictionless trade possible through regional agreements based on the current level of trade...

The spokes model is a recent framework to study n-firms spatial competition. In a spatial framework firms delivering their product can price discriminate with respect to consumers’ location. Conditions for the existence of a price-location equilibrium of the spokes model with delivered product are established in both the case where there are as many firms as spokes and in the case not all spoke...

How to cite this article: SHI-LIANG WU, PEIXUAN WENG and SHIGUI RUAN (2015). Spatial dynamics of a lattice population model with two age classes and maturation delay. This paper is concerned with the spatial dynamics of a monostable delayed age-structured population model in a 2D lattice strip. When there exists no positive equilibrium, we prove the global attractivity of the zero equilibrium. ...

We propose a general equilibrium model to study the spatial inequality of consumers and firms within a city. Our mechanics rely on Dixit and Stiglitz monopolistic competition framework. The firms and consumers are continuously distributed across a two-dimensional space, there are iceberg-type costs both for goods shipping and workers commuting (hence firms have variable marginal costs based on ...

We consider a model of (spatial) voting with endogenous timing. In line with actual political campaigns, candidates can decide endogenously when and where to locate. More specifically, we analyze endogenous timing in a two-period n-candidate spatial-votinggame. We show that this game possesses a pure-strategy equilibrium∗ (OSBORNE [1993]) but no – or only very complex – subgame-perfect equilibr...

To understand the impact of spatial heterogeneity of environment and movement of individuals on the persistence and extinction of a disease, a spatial SIS reaction-diffusion model is studied, with the focus on the existence, uniqueness and particularly the asymptotic profile of the steadystates. First, the basic reproduction number R0 is defined for this SIS PDE model. It is shown that if R0 < ...

In this paper, we present spatial price equilibrium network models, both static and adaptive, with differentiated products under perfect quality information for producers and consumers and under quality information asymmetry with consumer learning of product quality with a time delay. The adaptive model with information asymmetry is able to adapt to the uncertainty in consumer learning as well ...

Dynamics of Generalised Spatia! Interaction Models This paper analyses dynamic properties of generalised spatial interaction models, w'rth particular emphasis on Alonso's generai theory of movements. Although the application of this theory addressed in the paper is a muitiregional demographic stock-flow model, it can easily be shown that the approach can be generalised to all types of spatial i...
