Transport costs in address models of differentiation are usually modeled as separable of the consumption commodity and with a parametric price. However, there are many sectors in an economy where such modeling is not satisfactory either because transportation is supplied under oligopolistic...

This article presents a novel method of market delineation, which generates virtually isolated residential clusters using data on the spatial distribution of population. The performance of this approach is evaluated by contrasting it with traditional delineation techniques based on municipal...

Purpose of the article: This paper focuses attention on regional price indices (RPI) that reach across regions, respectively Czech regions, and different levels. Methodology/methods: The article mainly analyses the relation between the RPI and the particular form of market structures at the...

The New Economic Geography literature allows detailed analysis of the factors that determine the location decisions of firms in integrated markets. However, the competitive process is modelled in a rather rudimentary way, and the empirical evidence has usually been obtained from reduced-form...

We study the entry timing and location decisions of two exclusive buyer-supplier relationships in a continuous-time spatial competition model. In each relationship, the firms determine their entry timing and location, and negotiate a wholesale price through Nash bargaining. Then, the downstream...

The empirical literature on mergers, market power and collusion in differentiated markets has mainly focused on methods relying on output and/or panel data. In contrast to this literature we suggest a novel approach that allows for the detection of collusive behaviour among a group of firms...

The "spokes model" takes the name from its graphical visualisation, that resembles the spokes of a bike's wheel. It describes a market as a collection of spokes, joining at a common centre, where consumers are located. Firms may be situated at the extreme of these spokes, at the interior of the...

In this paper, I assume the existence of distribution of urbanamenities having its maximum at the city center. These amenities are viewed as a surrogate for all kinds of outside opportunities taht consumers encounter within urban areas. Using the Hotelling model, I study the impact of these...
