Inserting GM Products into the Food Chain : The Market and Welfare Effects of Different Labeling and Regulatory Regimes

The purpose of this article is to examine the system-wide effects of the introduction of genetically modified (GM) products with and without labeling and to compare these two regimes to a third regime where GM products are not present either because they have not yet been developed or because they have been banned. For each regime, the decisions and welfare of consumers, producers, and life science companies are examined. The article explicitly incorporates the consumer response to the introduction of GM technology and considers different market structures of the life science sector
