 On the regulation of spatial externalities: coexistence between GM and conventional crops in the EU and the ‘newcomer principle’Michele Graziano Ceddia, Mark Bartlett, Caterina De Lucia and Charles Perrings Australian Journal of Agricultural and Resource Economics, 2011, vol. 55, issue 01, 18 Abstract: Pollen-mediated gene flow is one of the main concerns associated with the introduction of genetically modified (GM) crops. Should a premium for non-GM varieties emerge on the market, ‘contamination’ by GM pollen would generate a revenue loss for growers of non-GM varieties. This paper analyses the problem of pollen-mediated gene flow as a particular type of production externality. The model, although simple, provides useful insights into coexistence policies. Following on from this and taking GM herbicide-tolerant oilseed rape (Brassica napus) as a model crop, a Monte Carlo simulation is used to generate data and then estimate the effect of several important policy variables (including width of buffer zones and spatial aggregation) on the magnitude of the externality associated with pollen-mediated gene flow.
