This study compares consumer valuations of beef steaks from cattle produced without growth hormones or genetically modified corn in France, Germany, the United Kingdom, and the United States. In general, European consumers place a higher value on beef from cattle that have not been administered growth hormones and/or fed genetically modified corn than United States consumers. There is a larger divergence between the two cultures with regard to the issue of biotechnology and genetic engineering than with the issue of growth hormones. Results suggest that liberalizing trade policy for hormone-treated beef may be welfare reducing for the European Union.
