Market Dynamics in Supply Chains: The Impact of Globalisation and Consolidation on Food Companie's Mark-ups

This paper examines whether ownership and increased competitive pressure affect food retailers’ market power, analysing whether all actors involved in the food supply chain deviate from the pricing behaviour that exists under perfect competition. A method proposed by Roeger (1995) is used to estimate price-cost margins, relaxing the assumptions of perfect competition and constant returns to scale. [Discussion Paper 273/2011].
