Indirect analysis of market power requires market delineation. Procedures in competition case law can be biased, as sample of market participants is typically biased or wrong one for analysis of market boundaries. Market delination can then be biased to too narrow markets, thus finding too much...

This paper analyses the extent of inter-format retail competition between supermarkets, discounters and drugstores in Germany, using data from the German market for diapers. We estimate a random coefficient logit model at the individual household level. Based on consumer substitution patterns,...

The purpose of this study is to analyse theoretically the implications of applying the procedure for market delineation used by competitions authorities in the EU and in the US. Specifically, we investigate the circumstances under which the procedure will lead to positive relation between actual...

Given various recent antitrust investigations on the retail sector, we deal with uncovering demand systems substitution patterns for a particular market (diapers) to investigate the inter-format competition (supermarkets vs. discounters vs. drugstores). Using the uncovered demand system we...

This paper proposes an iterative three-step spatial clustering procedure to define Functional Economic Market Areas (FEMAs) with an evolutionary computational approach using flow data on economic linkages. FEMAs are needed as basic observation units in disaggregated economic data analysis, since...
