We study spatial embeddings of random graphs in which nodes are randomly distributed in geographical space. We let the edge probability between any two nodes to be dependent on the spatial distance between them and demonstrate that this model captures many generic properties of social networks,...

This study examines how the institutional provisions of the Nice Treaty and the constitutional reform of the European Union (EU) will affect agricultural decision-making in the enlarged EU. Although the agricultural sector is a core EU policy domain, we have little knowledge about the effects of...

This paper performs the utilization of cellular automata computational analysis as the dynamic model of spatial epidemiology. Here, explored elementary aspects of cellular automata and its application in analyzing contagious disease, in this case avian influenza disease in Indonesia....

This paper analyzes factors that affect candidates’ position-taking incentives in multi-candidate and multi-party elections. Following Cox (1990), we define centrifugal incentives as those that motivate vote-seeking candidates to take more extreme positions relative to the center of the...

In two-party competition, it is well known that the party whose supporters/identifiers are more ideologically concentrated can pull the overall median in the direction of its party median, while the overall mean is essentially simply an average of the two party means weighted by the number of...

Why do both left and right political parties almost always propose progressive income taxation schemes in political competition? Analysis of this problem has been hindered by the two-dimensionality of the issue space. To give parties a choice over a domain which contains both progressive and...

We provide a model of environmental regulation to control transboundary pollution while considering the role of neighboring country regulations and measures of the quality of own and neighboring country government institutions. We apply a Spatial Durbin model to identify the determinants of the...
