Abstract	A plethora of research in recent years has been devoted to estimating consumer demand for genetically modified food, an important piece of information needed to create appropriate public policy. In this paper, we conducted a Meta analysis of 25 studies that report 57 valuations for GM food. We found that an econometric model that controls for a) the characteristics of the sample of consumers studied, b) method for eliciting the consumers' valuation, and c) characteristics of the valued food explains as much as 89% of the variation in existing value estimates for genetically modified food. Each of the aforementioned factors has a statistically significant effect on estimated premiums for non-GM food. Results of this study effectively summarize the extant literature on consumer demand for genetically modified food and permit the creation of some stylized facts that are not conditional on the results of one particular study. This paper also illustrates the effect of methodological choices on valuation estimates and reports a model that allows researchers and policy makers to easily generate valuation measures in line with what might be expected had a separate full-blown study been conducted.
