Antitrust - Case 7

Analysis of the empirical relationship between measures of buyer power and the outcome of bilateral negotiations in the grocery retailing industry

Abuse of dominance in the grocery retailing industry. The competition authority investigated whether a large retailer had abused its dominant position vis-à-vis dependent suppliers. E.CA assisted the retailer by analysing the empirical relationship between the dependency measure proposed by the agency and the outcome of bilateral negotiations between the retailer and various suppliers. The investigation involved hypothesis testing as well as regression analysis.
