An inconsistency is found in the demand side of the NEG models developed in Pflüger (2004) that follows from the absence of a non-negativity constraint on the consumption of agricultural goods. This seriously weakens the results of the original paper and those of ensuing contributions in...

This paper extends the Puga (1999) model by introducing urban frictions. It assumes that the agglomeration of manufacturing in a city imposes a cost on the inhabitants of the agglomerated region. Furthermore, an implicit function methodology is developed to provide a numerical stability function...

This paper attempts to model directly the folk theorem of spatial economics, according to which increasing returns to scale are essential for understanding the geographical distributions of activity. The model uses the simple structure of most New Economic Geography papers, with two identical...
