This paper considers the empirical assessment of the relationship between prices and number of firms in local markets in geographic or, more generally, characteristic space and its use as evidence in merger cases. It outlines a structural, semi-nonparametric econometric model of competition in...

The paper presents a detailed documentation of the underlying concepts and methods of the Spatial Agent-based Competition Model (SpAbCoM). For instance, SpAbCoM is used to study firms' choices of spatial pricing policy (GRAUBNER et al., 2011a) or pricing and location under a framework of...

In standard models of New Economic Geography the overall regional price index in the centre is lower than in the periphery, because trade in manufacturing imposes transportation costs whereas trade in agriculture is assumed to be costless. Since real world observations suggest higher overall...

The purpose of this paper is twofold. First, we present a new model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this framework can be...

In view of the lack of area-wide regional price data, Aten and Heston (2005) adopted an econometric approach in estimating regional price level from an international perspective. At a regional level, however, spatial economic theory may contribute to advancement in explaining price level...

This paper reports an experiment on a location game, the so-called "Price-Competition on the Circle." There are n symmetric firms equidistantly located on a circle. Consumers are uniformly distributed. Each consumer buys one and only one unit from that firm whose price, including the cost of...

It is established that with the reduction of trade barriers the number of competitors on the spatial markets involved increases. This increase has short run consequences for price competition. If the trade liberalisation is anticipated by the domestic producers they will respond by changing the...
